 RETARDATION IN THE ELEMENTARY SCHOOLS OF 
 
 PHILADELPHIA. 
 
 By Byron A. Phillips, Ph.D., 
 
 Philadelphia. 
 
 I. 
 
 In the following study all pupils will be classed as retarded, 
 who are one year or more behind the "normal" grade for their age. 
 The universality of retardation is what first strikes the student of 
 the problem. Whenever there is a school system, this phenomenon 
 is present. Upon further consideration, however, we must recog- 
 nize that retardation is dependent to a great extent upon the 
 natural inequalities of the human mind, which may be of any 
 grade from the lowest to the highest intelligence. At one end of 
 the series we have the profound idiot, at the othei%the genius. 
 Somewhere between these extremes we find the average or "normal" 
 mind. The curricula of the public school systems are supposed to 
 be adapted to this average, normal, or standard. Of course this 
 average mind will not be one determined by a strict criterion, but 
 will range within certain limits. Minds below the lower limit will 
 not fit into a school system based upon this average, and a certain 
 amount of retardation will always exist. Investigation, however, 
 reveals the fact that many pupils of average intelligence are 
 retarded to such an extent that the school systems have been called 
 in question as inefficient. 
 
 Besides natural inferiority of mind, there are several other 
 factors which cause retardation, the most important of these being 
 irregular attendance and lack of proper medical inspection. These 
 factors are present in all school systems to a greater or less extent, 
 yet there are great differences in the amount of retardation among 
 the different systems. 
 
 In studying the retardation of any system, the relation of the 
 retarded to the normal and to the accelerated should be taken into 
 account if we are to obtain an adequate idea of the relative worth 
 of the system. 
 
 The present study is an investigation of retardation in the 
 elementary public schools of Philadelphia, and a word as to the 
 organization of the system will make clearer the significance of 
 the results. At the head is a Superintendent of Public Instruc- 
 tion, who is assisted in his duties by four Associate Superin- 
 tendents. The city is divided into ten districts, each under a Dis-

 trict Superintendent. Each district includes within its jurisdic- 
 tion several contiguous political wards. In all there are 232 schools 
 having an average enrolment of 81,768 boys and 82,127 girls, a 
 total of 163,895 pupils. Age tabulations are taken on the number 
 of pupils in actual attendance on one day of the year, and the 
 regulation retardation blank is used for this purpose. A child 
 eight years or over in the first grade is considered retarded; nine 
 years or over in the second grade, and so on through the grades. 
 In the present study the age tabulations for 1909 are used as a 
 basis, and occasional reference is made to those of 1908 and 1910 
 for comparison. 
 
 Retardation for the Years 1908, 1909 and 1910. 
 
 From Dr. Oliver P. Cornman's study of the "Ketardation of 
 the Pupils of Five City School Systems," 1 we see that the different 
 cities vary greatly in the percentage of retardation. In a more 
 detailed study of any particular system it is desirable to ascertain 
 whether the rate of retardation is uniform throughout the system 
 or not. The ten districts readily lend themselves to such a study. 
 
 In 1908 the highest amount of retardation for boys was 50.6 
 per cent in District 3, and the lowest 37.9 per cent in District 10, 
 a difference of 12.7 per cent; for girls 46.5 per cent in District 4, 
 and 32.8 per cent in District 10, a difference of 13.7 per cent; 
 and for both 48.3 per cent in District 3, and 35.4 per cent in 
 District 10, a difference of 12.9 per cent. 
 
 In 1909 we find the following range of difference in the 
 amount of retardation in the districts: boys, from 48.1 per cent 
 in District 3, to 35.9 per cent in District 10, a difference of 12.2 
 per cent; girls, from 45.8 per cent in District 3, to 30.6 per cent 
 in District 10, a difference of 15.2 per cent; both, from 47.0 per 
 cent in District 3, to 33.3 per cent in District 10, a difference 
 of 13.7 per cent. 
 
 In 1910 the greatest amount of retardation for boys was 48.4 
 per cent in District 3, and the least 34.6 per cent in District 7 
 a difference of 13.8 per cent; for girls 45.7 per cent in District 3, 
 and 30.7 per cent in District 10, a difference of 15 per cent; and 
 for both 47.6 per cent in District 3 and 33.0 per cent in District 7, 
 a difference of 14.6 per cent. 
 
 The other eight districts range in retardation between the 
 extremes just cited. It is apparent that different causes are work- 
 ing in different degrees in these districts to cause the variations in 
 the amount of retardation among them. The following table

 Studying this table we note its remarkable regularity. Each 
 year in each district the retardation of the boys is less than that 
 of the previous year; each year in each district the retardation of 
 the girls is less than that of the previous year; each year in each 
 district the totals are less than the totals of the previous year. We 
 can almost see retardation being forced down by some external 
 cause. Since the problem of retardation is occupying the attention 
 of most departments of superintendence, we may infer that this 
 decrease is due to supervision. The following table summarizes 
 the retardation statistics for the three years in question :

 Not only the districts but the grades, with a few trifling 
 exceptions, show the same uniform reduction in retardation.

 No one familiar with the problem of retardation would look 
 for equal amounts of retardation in the different grades. The 
 grade figures for the whole city, arranged in order of the amount 
 of retardation, are for 1909 :

 The figures for 1910, although somewhat smaller, follow those of 
 1909 in order of grades. 
 
 Summary : 
 
 (1) The ten districts vary considerably among themselves in 
 amount of retardation. 
 
 (2) There has been a uniform reduction in the amount of 
 retardation during the past three years in the city as a whole, in 
 each district, and with a few exceptions in each grade. 
 
RETARDATION IN PHILADELPHIA. 5 
 
 (3) Supervision is probably an important factor in this 
 reduction of retardation. 
 
 Attendance. 
 
 Some investigators have considered attendance to be the lead- 
 ing factor in retardation. A comparison of retardation figures 
 with the statistics of attendance given in the Superintendent's 
 annual report, fails to reveal any correlation. For 1909 District 3 
 has the greatest amount of retardation, 47. per cent, and an 
 average attendance of 90.9 per cent; while District 10 has the 
 lowest retardation, 33.3 per cent, and an average attendance of 
 89.9 per cent. The ten districts show the following percentages of 
 retardation and attendance respectively :

 In order to obtain a measure of the general tendency of a 
 relationship between two variable quantities with unknown zero 
 points and units directly incommensurable, it is necessary to find 
 the coefficient of correlation. The Pearson method obtains as its 
 measure of the relationship a single number which may be any- 
 where between 1.00 and — 1.00. The method of calculating the 
 Pearson coefficient of correlation is to multiply the deviation of 
 each observation from the average in one trait, by its deviation 
 from the average in the other ; to add the products thus found and 
 divide the sum by the number of cases times the standard deviation 
 of the first trait times the standard deviation of the second trait 
 That is, the coefficient of correlation 
 
 r = 
 
 n o"x 02 
 
 The coefficient of correlation obtained by this method for the 
 relationship between retardation and attendance for the year 1909 
 is .05, which signifies practically a lack of correlation. A study 
 
6 THE PSYCHOLOGICAL CLINIC. 
 
 of the grade figures shows a similar lack of correlation between 
 the percentages of retardation and of attendance. From this it 
 would seem that attendance is a minor factor in causing retarda- 
 tion, but this is evidently untrue, for two reasons. In the first 
 place the percentage of retardation is being compared with the 
 percentage of attendance for the same year. The attendance in 
 any year cannot be a cause of retardation for the same year, 
 although percentages of attendance vary but little from year to 
 year. Secondly, the method of calculating attendance is apt to 
 convey a false impression of the actual conditions in the various 
 schools and districts. The attendance here, as in most school 
 reports, is given in the form of a per cent of the average number 
 belonging or the average number present for month and year. In 
 such a calculation a difference of one or two per cent may mean a 
 difference of hundreds of half-day attendances, and even tenths of 
 a per cent may mean no small factor. No doubt the true way to 
 estimate the exact influence of irregular attendance on retardation 
 would be to keep a record of the number of half-day attendances 
 for each pupil and compare the results with the promotion record 
 of the same pupil. 
 
 It is to be noted that District 3, with the highest percentage 
 of retardation, is a compact foreign district ; while District 10, 
 with the lowest percentage, is a rural American district, so it 
 would seem that other factors, in this case the nature of the 
 sociological unit, may overbalance the factor of attendance. 
 
 The influence of attendance may be seen by comparing the 
 attendance of the colored schools with that of the district in which 
 they are located. The J. Miller School has an average attendance 
 of 83.7 per cent, District 1 an average attendance of 88.3 per cent ; 
 the Pollock School has an attendance of 83.5 per cent, District 3, 
 90.4 per cent; the Catto School has an attendance of 80.7 per cent, 
 and the Ramsay School, 76.3 per cent, District 4, 87.7 per cent; 
 the Vaux School has an attendance of 76.0 per cent, District 6, 
 87.6 per cent; the Hill School has an attendance of 80.2 per cent, 
 the Meehan School, 80.0 per cent, District 9, 88.7 per cent; the 
 Wilmot School has an attendance of 84.7 per cent, District 10, 
 89.0 per cent. When retardation in the colored schools is dis- 
 cussed it will be seen that in every case it is approximately from 
 10 to 20 per cent higher than that for the district. 
 Summary : 
 
 (1) The method of reckoning attendance used in compiling 
 school reports gives results which are of small value for statistical 
 purposes. 
 
RETARDATION IN PHILADELPHIA. 7 
 
 (2) While the tables do not show any correlation between 
 retardation and attendance, no doubt such relationship exists, and 
 is an important but not the predominating factor in causing 
 retardation, being overbalanced in various districts by a single 
 potent factor or several factors working together. 
 
 Retardation in Relation to the Sociological Unit. 
 
 The city of Philadelphia spreads over a considerable area. 
 Originally many parts of the present city were towns in them- 
 selves, which have been incorporated into the city in the course of 
 its growth. Many of these sections still retain their old character- 
 istics. The center of the city contains the great business section. 
 South of this we find the foreign element, consisting mostly of 
 Italians and Russian Jews. In the northeast there is a great 
 factory district, in the northwest a wealthy residential district 
 including Tioga and Germantown. West Philadelphia is char- 
 acterized by the homes of the average American workingman. 
 
 The ten districts, generally speaking, may be said to have the 
 following characteristics : District 1, rather poor social class work- 
 ing in factories in the 40th and 36th wards, with a better residen- 
 tial section in the 46th and 27th wards ; District 2, Americans of 
 the lower class, with a large foreign element; District 3, almost 
 entirely foreign, with a considerable colored element; District 4, 
 business section, old aristocratic section, large colored element, 
 and west of the Schuylkill residential ; District 5, residential, with 
 large colored element, business section; District 6, large foreign 
 element, large colored element, poor laboring class, and in the 32d 
 ward a better residential section; District 7, factory section; 
 District 8, good residential section, also factories ; District 9, good 
 residential section with one factory ward; District 10, rural out- 
 lying district, factory districts with small settlements of foreigners. 
 We can readily see that District 3, composed almost wholly of 
 foreigners, and District 4, with a large negro element, have the 
 greatest amount of retardation ; and that Districts 2, 5 and 1, with 
 a considerable foreign element and poor home conditions, follow. 
 District 6, although having a large foreign element, has a counter- 
 balancing factor in a better residential section. District 8, besides 
 a large residential section, has a considerable factory element to 
 augment the retardation. District 7 has a low percentage of retar- 
 dation, although of a rather low social order, but its low rate of 
 retardation will be seen to be due in part to the high elimination 
 rate and to the absence of the negro element. Districts 9 and 10 
 with low retardation rates are partly rural and residential. 
 
8 THE PSYCHOLOGICAL CLINIC. 
 
 We can see that each district is too large to permit us to 
 establish a relation between the social condition and retardation, 
 except in a general way. Each district, however, is composed of a 
 number of political wards, some of which are nearly homogeneous 
 socially. In District 1 the retardation is 41.8 per cent, the wards 
 with poor social conditions showing about 3 per cent more retarda- 
 tion and the better residential wards about 3 per cent less. For 
 District 2, with 44.5 per cent of retardation, the ward retardation 
 is fairly uniform. In District 3, with a retardation of 47.0 per 
 cent, the greatest variation is in the 30th ward, which has 42.9 
 per cent. In District 4, with a retardation of 45.1 per cent, the 
 7th ward has 62.2 per cent (colored), and the 9th ward 57.8 per 
 cent. The latter is a business section with very poor and hetero- 
 geneous elements in the smaller streets. In District 5 the retarda- 
 tion is 44.7 per cent, and shows the 10th ward with 5 3.' 7 per cent 
 of retardation. This is also a business section with many apart- 
 ment houses, and with a poor social element in the side streets. 
 District 6, with 37.2 per cent of retardation, shows 45.1 per cent 
 in the 14th ward, which has a considerable negro element besides a 
 large number of foreigners. The 32d ward, which is a very 
 good residential section, has a retardation rate of only 33.6 per 
 cent. District 7, with 35.5 per cent of retardation includes the 
 factory wards, and there is not much difference in the percentage 
 of retardation among them. District 8, with 38.5 per cent of re- 
 tardation includes the 21st ward with 34.3 per cent, showing the 
 effect of rural conditions. District 9, with 36.0 per cent of retard- 
 ation, shows the 22d ward with 40.1 per cent. This ward includes 
 two colored schools. The 43d ward has a retardation rate of 34.6 
 per cent. This is a good residential section. District 10, with 
 33.3 per cent of retardation, shows 29.9 per cent in the 25th ward 
 and 37.3 per cent in the 45th ward. The former is a factory dis- 
 trict, which has a rather low rate of retardation owing to the high 
 elimination, while the latter contains a large percentage of foreign- 
 ers, with a number of parochial schools, which always increase the 
 rate of retardation. 
 
 Many wards are differently constituted socially in their 
 various parts, so that it would be profitable to investigate further 
 the separate schools in each ward. The table on page 9 gives in 
 more detail the social components of District 6. 
 
 District 6 comprises five wards. In the 12th ward, which 
 contains only two colored schools, the retardation is 34.8 per cent, 
 although the schools contain 80 and 90 per cent of foreigners, but

 these schools contain grades 1 to 4 only. In the 13th ward the 
 Warner School, with 80 per cent of foreigners, has 37.6 per cent 
 of retardation. The Wyoming School has 44.1 per cent of retarda- 
 tion, about the average percentage for schools having a large 
 foreign element. The schools of the 20th ward have a rather low 
 percentage of retardation, considering the social components of the 
 schools. The Lynd School has 44.3 per cent of retardation, with 
 70 per cent foreign and 25 per cent colored. The 32d ward shows 
 a considerable decrease in retardation, the ward retardation being 
 only 33.6 per cent, with no school varying much from the average 
 except the Allison School, with only 29.0 per cent of retardation, 
 and the Stokley School with 21.5 per cent. These schools are not 
 fully graded, and draw their pupils from very good residential 
 districts. 
 
 We see that city, district, ward, and school are made up of 
 distinct sociological units. In each of these units the home condi- 
 tions are widely different. In those districts where retardation is 
 greatest, the sociological unit proves to be the one in which home 
 conditions are most unfavorable and even antagonistic to educa- 
 tional influence. A course of study has been prescribed for the city 
 as a whole, as if the various districts were homogeneous units, equal 
 sociologically and intellectually. This course of study is to be fol- 
 lowed as closely for the foreigners in District 3, as for the native 
 Americans in District 10. Can we expect equal results when we 
 apply the curriculum inflexibly to these widely divergent social 
 units ? We must conclude that retardation is in a great measure 
 the resultant of unfavorable home conditions, combined with an 
 inflexible curriculum. 
 
 Supervision may overcome to a certain extent adverse condi- 
 tions, by taking these facts into consideration. The standards of 
 requirement must be differently applied to the different sociological 
 groups. In District 6, for example, we expect to find a large per- 
 centage of retardation, for here are a large foreign element, a 
 large colored element, and (with the exception of the 32d ward) 
 poor social conditions; yet in this district with a comparatively 
 poor element from which to draw, we find a comparatively low rate 
 of retardation. Why is it that the retardation in schools with 60 to 
 80 per cent of foreigners does not begin to be as great as that in 
 schools in other districts where conditions are approximately the 
 same? This district has been under the superintendence of one

 who has been especially interested in the problem, and it would be 
 fair to say that the course of study has been interpreted less rigidly 
 and more in accord with the needs of the sociological unit. 
 
 A closer study of the colored and foreign elements brings to 
 light facts which substantiate the conclusions already drawn. 
 
 The Colored Element. 
 
 In most of the schools of Philadelphia, white and colored 
 pupils are mixed in varying proportions, according to the district. 
 There are nine schools for colored children exclusively. The 
 following table shows a surprising contrast between these schools 
 and the others:

 In District 1 the J. Miller School has 68.2 per cent of re- 
 tardation, against 41.8 for the district, the school having the next 
 highest amount of retardation being the Boon's Dam, with 49.1 
 per cent (8 per cent colored). In District 3 the Pollock School 
 has 60.6 per cent of retardation, against 44.5 per cent for the 
 district, the school having the next highest amount of retardation 
 being the Florence, with 56.0 per cent (nearly 100 per cent for- 
 eign). In District 4 the Catto School has 67.3 per cent of re- 
 tardation, and the Ramsey TO. 9 per cent, against 45.1 per cent 
 for the district. The Keystone School, 44 per cent colored, has 
 the next highest amount of retardation, 57.8 per cent. In Dis- 
 trict 6 the Vaux School has 66.3 per cent of retardation, against 
 37.2 per cent for the district. The Hancock School (13 per cent; 
 
12 THE PSYCHOLOGICAL CLINIC. 
 
 colored), with 47.4 per cent retardation, has the next highest 
 percentage. In District 9 the Hill School and the Meehan have 
 72.8 per cent and 58.2 per cent of retardation respectively, against 
 36 per cent for the district. The Gilbert School (6 per cent 
 colored), with 51.6 per cent, stands next. The high percentage 
 of retardation here, however, seems to be due to local causes, as 
 the Harmer, which is next below, has only 45.0 per cent, and the 
 percentages of retardation of the schools below this fall off nor- 
 mally. In District 10 the Wilmot School has 59.3 per cent of re- 
 tardation, against 33.3 per cent for the district, the next school 
 being the Martin, with 51.1 per cent. This school has a large 
 foreign element and also draws, a number of its pupils from three 
 parochial schools in the neighborhood. The Marshall School fol- 
 lows the Martin, with 46.5 per cent, after which comes the Lawn- 
 dale, with 40.2 per cent, which is more typical of the district. 
 
 In every case the colored schools are far above the others in 
 the amount of retardation. Taking the schools with 20 per cent 
 colored children or over, we can see an increase as a whole in 
 retardation. With 8188 colored pupils showing so great an amount 
 of retardation, it is obvious that the total retardation is affected. 
 In comparing the grades this colored retardation is a considerable 
 factor, as the colored pupil does not often get above the sixth grade 
 before leaving school. One result of this is to swell the amount of 
 retardation in the fourth and fifth grades. 
 
 If we look over the retardation of the several districts we 
 see that District 7 has practically no negro element and that in 
 Districts 8 and 10 the negro element is only 2.1 per cent and 1.4 
 per cent respectively. District 6, on the other hand, has a large 
 percentage of colored pupils (7.1 per cent) and still has a com- 
 paratively low rate of retardation. Districts 3 and 4 have the 
 largest percentages of retardation and also the largest proportion 
 of negroes. It is not contended that the negro element is the prin- 
 cipal cause of the greater retardation in these districts, but that 
 it is one of the factors. This sociological element influences the 
 whole system and adds to the amount of retardation. It is a ques- 
 tion whether the course of study is suited to the negroes, as the 
 educational results are so far behind those in the other schools, 
 and it is very doubtful whether even a liberal interpretation of the 
 course of study would meet the educational necessities of this 
 group. 
 
II. 
 
 The Foreign Element. 
 
 The foreign element raises the retardation above the average 
 for the city, but not to as great an extent as the negro element. In 
 studying this phase of the problem, such detailed statistics as ob- 
 tained for the colored pupils were not available. We have secured, 
 however, a list of the schools in Districts 1, 2, 3, 5, 6 and 10 
 with over 25 per cent of foreign pupils. Districts 8 and 9 have 
 no schools with over 25 per cent foreign. By foreign is here 
 meant those whose home conditions are characterized by foreign 
 customs and speech. 
 
 Note must be taken not only of the rate of retardation of the 
 school, but of the number of pupils and the grades in the schools, 
 as the retardation in schools with grades 1 to 4 only, no matter 
 what the conditions are, will be less than in fully graded schools. 
 This is true to a less extent of schools which contain grades 1 to 
 4 only. The table on page 14 shows the retardation of schools 
 with over 25 per cent foreign pupils for six of the districts. 
 
 From this table we see that the schools with 25 per cent or 
 more of foreign pupils range in retardation from 40 per cent up- 
 ward. In some schools the percentage of foreign pupils rises to 
 100 per cent, but in no school does the retardation equal that of 
 the colored children. In schools with only 25 per cent foreign, 
 other causes may reduce retardation. 
 
 It is curious to note the relatively small percentage of re- 
 tardation in some of the schools of District 6 with 80 per cent 
 and 90 per cent foreign, besides a considerable colored element : 
 
 Mifflin School, 90 per cent foreign, with 32.3 per cent retarded

 Warner " 80 " " " 37.6 
 
 Penn " 80 " " " 36.6 
 
 Webster " 40 " " " 32.3 
 
 These schools contain grades 1 to' 4 only, but may be compared with 
 schools of the same grades in Districts 2 and 3, where the retard- 
 ation is 40 to 50 per cent.

RETARDATION IN PHILADELPHIA. 15 
 
 Summary : 
 
 (1) The home conditions of the sociological units are an im- 
 portant factor in retardation. 
 
 (2) The negro element is out of accord with the educational 
 system, and is an important factor in retardation. 
 
 (3) The same thing is true of the foreign element, to a less 
 extent. 
 
 (4) Supervision may reduce retardation by a more liberal 
 interpretation of the course of study. 
 
 Retardation in the Schools. 
 
 "When comparing the retardation of different districts, it is 
 desirable to know whether the retardation in each district is 
 uniform throughout or whether the average is raised or lowered by 
 certain schools. In the table on page 16 the schools in each dis- 
 trict are arranged in groups according to their percentage of re- 
 tardation, e. g., there are four schools in District l*with between 
 35 and 40 per cent of retardation, four schools with between 40 
 and 45 per cent, and so on. 
 
 The first thing to note is the high percentage of retardation 
 in the colored schools, the next is the comparatively low retarda- 
 tion of schools with grades 1 and 2, or 1 to 4, only. The retarda- 
 tion in Districts 2, 5, 7 and 8 is more uniform than in the other 
 districts. 
 
 The schools in Districts 2, 3, 4 and 5 are much larger than 
 those of Districts 9 and 10. In the former districts there are 
 fewer fully graded schools, while in the latter group, especially 
 District 10, the fully graded schools predominate. This is due, 
 of course, to rural conditions. In these schools there seem to be 
 conditions favorable to greater understanding of the individual 
 needs of the child, owing probably to the fact that many of the 
 schools are small and have few pupils in each grade. In the 
 larger schools of the congested districts the loekstep of the cur- 
 riculum must be preserved, even where individual instruction is 
 most needed. This has the effect of augmenting the amount of 
 retardation. Deficiency in certain branches, notably arithmetic 
 and spelling, often is the cause of a pupil's failure to advance. 
 Individual attention is not to be had, and the pupil's entire edu- 
 cation must be neglected while he is making futile efforts to reach 
 a fixed standard in these branches. Promotions should be made 
 according to individual need, not by a fixed rule for the average 
 child. A course of study must be liberally interpreted in the

 classroom. In every class are found the bright pupils, the average 
 pupils, and the slow pupils. If the amount of detail required 
 were varied to suit the ability of these three kinds of children, 
 much retardation would be avoided. This is only another example 
 of what may be accomplished by supervision.

 Acceleration. 
 
 In previous studies of retardation little attention has been 
 given either to pupils of normal age for their grades, or to acceler- 
 ated pupils. The following table summarizes the retardation,

 The percentage of pupils making normal progress ranges only 
 between 28.5 per cent in District 3, and 32.3 per cent in District 
 6, an average of 30.5 per cent. This is practically the same for 
 boys as for girls, the former being 30.2 per cent, the latter 30.6 
 per cent. Acceleration has a wider range, from 24.5 per cent in 
 District 3 to 35.4 per cent in District 10. The girls are more 
 accelerated than the boys, and are less retarded, but the percentage 
 of girls making normal progress is about the same. Studying the 
 separate schools in each district, it is found that the normal-prog- 
 ress pupils range only between 28 and 33 per cent. This holds 
 s:ood for the schools in Districts 3 and 4 where retardation is 
 greatest, as well as for Districts 7 and 10 where it is least. The 
 acceleration in the schools of the different districts varies consid- 
 erably, and we may say that the acceleration varies approximately 
 inversely as the retardation, while normal progress remains ap- 
 proximately a constant. The following table summarizes the 
 retardation, normal progress and acceleration for the city.

 A study of the districts by grades shows that the normal 
 remains approximately at 31 per cent for grades 8, 6, 3, 2 and 1, 
 but falls off in grades 5 and 4, where the retardation is greatest, 
 to 26.2 per cent and 25.9 per cent respectively. It rises in grade 
 7 to 36.2 per cent. The acceleration bears a more direct relation 
 to the retardation, the grade with a high retardation rate having 
 a low acceleration rate and vice versa. The lowest acceleration is 
 in grades 5 and 4, which have 19.1 per cent and 20.4 per cent 
 respectively. The highest acceleration, 49.1 per cent, is in the 
 first grade, due, of course, to early entrance. The eighth grade 
 has the next highest percentage, 35.1 per cent. The following 
 table gives the summary by grades for the city.

 extends through only two years.

 THE PSYCHOLOGICAL CLINIC. 
 
 In all districts together there are approximately 20 per cent 
 retarded one year, 10 per cent retarded two years, 5 per cent 
 retarded three years, and 3 per cent in Districts 1 to 6 and 1.5 
 per cent in Districts 7 to 10 retarded four years. The difference 
 in acceleration is very marked. The acceleration for one year 
 ranges from 22.0 per cent in District 2 to 32.2 per cent in District 
 10, but for two years it ranges only from 2.1 per cent in Districts 
 3 and 4 to 3.5 per cent in District 7. 
 
 Retardation for one year is the same for both boys and 
 girls, 21.0 per cent, but retardation for two, three and four years 
 is higher for boys than for girls. The following table gives a 
 summary for the city:

 The most interesting fact in this study is brought out by a 
 comparison of the normal and accelerated pupils for the years 
 1908, 1909 and 1910. These tables have been compiled in the 
 same manner as those for the retardation for the same years for 
 boys, girls and both, for the ten districts.

 As the retardation for the years 1908, 1909 Aid 1910 has 
 decreased from 42.4 per cent to 40.3 per cent and then to 38.8 
 per cent, we should expect to find an increase in the amount of 
 normal progress, but such is not the case. It is true there is a 
 slight increase for 1909, but 1910 shows a very slight falling off. 
 The acceleration, on the other hand, shows a corresponding regu- 
 lar increase for boys as well as girls, averaging 28.4 per cent for 
 1908, 29.2 per cent for 1909, and 30.6 per cent for 1910. From 
 this it would seem that retardation is being increased as a result of 
 supervision, which is pushing up pupils all along the line. This 
 has been the true state of affairs, and furthermore, provision has 
 been made in the system for the more rapid advancement of 
 brighter pupils by means of the so-called "incidental promotion". 
 The tendency thus shown to decrease the inflexibility of the cur- 
 riculum is an undoubted sign of progress. The relation of 
 retarded, normal, and accelerated pupils for the years 1908, 1909 
 and 1910, may be graphically represented in the table on page 
 116. 
 
 Summary : 
 
 (1) There is a considerable percentage of pupils accelerated, 
 as well as of those retarded; 28.1 per cent of the boys are accel- 
 erated to 41.7 per cent retarded; 30.2 per cent girls accelerated 
 to 39.2 per cent retarded; while 29.2 per cent of all pupils are 
 accelerated to 40.3 retarded. 
 
 (2) The percentage of pupils making normal progress ap- 
 pears to remain a constant for boys and girls at about 30 per 
 cent.

 THE PSYCHOLOGICAL CLINIC. 
 
 (3) While retardation has decreased during the past three 
 years, the amount of normal progress has remained approximately 
 the same, and acceleration has increased. This is to be accounted 
 for by the effect of supervision in encouraging promotions all 
 along the line.

 The overcrowded condition of some Philadelphia schools sug- 
 gests that this condition may have an important bearing upon 
 the relative amount of retardation in the overcrowded districts. 
 For a study of this aspect of the problem there should be available 
 the number of pupils in each class in each school, with the promo- 
 
RETARDATION IN PHILADELPHIA. 23 
 
 tion record of each class. This information not being accessible, 
 the following study has been based npon the number of pupils in 
 the primary grades (one to four) of each school and the number 
 of primary teachers in the same school, and upon the number of 
 pupils in the grammar grades (five to eight) with the correspond- 
 ing number of grammar teachers in each school. There is an ad- 
 vantage in this division, as it is in the primary grades that over- 
 crowding chiefly occurs and elimination is at the minimum. 
 
 A study of the separate schools of the districts fails to reveal 
 any constant relation between the number of pupils per teacher 
 and the percentage of retardation. If the results of the investiga- 
 tion of the separate schools are summarized by districts, it is 
 seen that Districts 1 and 2 show five pupils per teacher more in 
 the primary than in the grammar grades, with 5 per cent greater 
 retardation in the latter than in the former. District 3 shows 41.8 
 pupils per teacher in the grammar grades to 47.8 in the primary, 
 with 49.1 per cent of retardation in the former to 46.4 per cent 
 in the latter. District 4 shows 41.0 pupils' per teacher in the 
 grammar, to 44.4 in the primary, with 52.4 per cent of retardation 
 in the former to 41.2 per cent in the latter. District 5 has 40.9 
 pupils per teacher in the grammar to 44.5 in the primary, with 
 52.1 per cent of retardation in the former to 41.8 per cent in the 
 latter. The greatest divergence between grammar and primary 
 retardation, with the least difference in number of pupils per 
 teacher in grammar and primary grades is in District 6, with 40.2 
 pupils per teacher in the grammar and 43.4 in the primary, with 
 a grammar retardation of 45.4 per cent as against 32.6 per cent 
 in the primary. District 7 shows 43.6 pupils per teacher in the 
 grammar, 44.5 in the primary, with 40.2 per cent of retardation 
 in the former and 33.2 per cent in the latter. In District 8 there 
 are 42.4 pupils per teacher in the grammar, to 45.5 in the primary, 
 with a retardation of 44.3 per cent in the former and 36.5 per 
 cent in the latter. District 9 has 42.4 pupils per teacher in the 
 grammar and 46.7 in the primary, with a retardation of 43.1 
 per cent in the former to 33.9 per cent in the latter. District 10 
 has 42.4 pupils per teacher in the grammar to 43.8 in the primary, 
 with a retardation of 37.1 per cent in the former to 32.2 per cent 
 in the primary. 
 
 Here again there seems to be no relation between district 
 retardation and the number of pupils per teacher in the district. 
 It appears that the primary grades may have more pupils per 
 teacher than the grammar grades, and still do equally if not more

 efficient work as measured by the criterion of retardation. This 
 may be due to the higher requirements in the grammar grades. 
 The controlling factor, as shown by the study of individual schools, 
 seems to be the teacher. A good teacher with a large class will 
 get better results than a poor teacher with a small one. 
 
 Elimination. 
 
 If all children remained in school until they had completed 
 the course as prescribed for the elementary grades, the comparative 
 amount of retardation between cities and the districts of the 
 same city would roughly measure the efficiency of the system. At 
 the age of fourteen years, working certificates may be obtained, 
 and elimination begins. A district with a low percentage of 
 retardation may have a high rate of elimination, the rate of retar- 
 dation appearing low because of the fact that many pupils drop 
 out, who, if they remained, would raise the retardation rate. The 
 reverse may also be true, namely, a district with a high rate of 
 retardation may have a comparatively low elimination rate. In 
 calculating elimination the method employed by Ayres has been 
 used. 
 
 In the following table the percentage of elimination has been 
 computed for boys, girls and both for the ten districts :

RETARDATION IN PHILADELPHIA. 25 
 
 It will be noted that the rate of elimination for girls is less 
 than that for boys, being 61.7 per cent for the former with 39.2 
 per cent of retardation, and 65.6 per cent for the latter with 41.7 
 per cent of retardation. The elimination rate for both is 63.3 
 per cent as against 40.3 per cent of retardation. 
 
 In table XVIII B the districts have been arranged accord- 
 ing to the amount of retardation with the corresponding elimina- 
 tion. District 3 has the highest rate of retardation and also of 
 elimination. Districts 4, 5 and 2 vary little in retardation, but 
 Districts 4 and 5 have much lower rates of elimination than Dis- 
 trict 2. District 1 has a medium retardation rate, and likewise 
 a medium elimination. District 8 has a retardation which is 
 higher by 2 per cent than that of District 9, but its elimination 
 rate is lower by 11 per cent. District 6 has a rather low rate of 
 retardation, and the lowest elimination. District 7 with a retar- 
 dation of only 35.5 per cent has an elimination of 72.0 per cent. 
 This great elimination accounts for a mill district wiw poor social 
 conditions having such a low rate of retardation. District 10 
 has the lowest retardation rate, 33.3 per cent, and also a low 
 elimination rate, 58.3 per cent. District 6 has a retardation of 
 37.2 per cent with an elimination of 53.6 per cent. The retarda- 
 tion and elimination rates of Districts 6 and 10 taken together 
 tend to approximate each other, but the social conditions are very 
 different in the two districts. It would seem from what has 
 already been said of District 6 that the adverse conditions had, in 
 a measure, been overcome by supervision. The elimination is low 
 because the retardation is low. It is failure to advance that raises 
 the elimination, as may be seen by the dropping out of large 
 numbers of pupils after the semi-annual promotions. 
 
 District 7, with a retardation of 35.5 per cent and an elimin- 
 ation of 72.0 per cent, seems to contradict the statement just made, 
 but it must be remembered that District 7 is a factory district 
 where it is customary for the children to go to work as soon as 
 they are fourteen years old. It seems that foreign parents are 
 more anxious that their children should remain in school, when 
 this is possible, if they are making progress. 
 Summary : 
 
 (1) The retardation rate is often misleading in making 
 comparisons where the elimination rate is not known. 
 
 (2) The less retardation, if we except abnormal conditions 
 (large proportions of foreign or negro population, factory districts, 
 and in general very low social conditions), the less elimination 
 we find.

 (3) Supervision may, by decreasing retardation, also lower 
 the elimination rate. 
 
 Retardation by Districts According to the Falkner Method. 
 In a recent article by Falkner 1 in The Psychological 
 Clinic, the common method of calculating retardation has been 
 objected to as being cumbersome and not giving the true amount 
 of retardation, because it fails to recognize elimination, which 
 begins at fourteen years of age. It is suggested that retardation 
 be calculated on a basis of the number of thirteen-year-old pupils 
 who have not reached a certain grade, in other words that retar- 
 dation be calculated at its maximum. The following table com- 
 pares the retardation of the ten districts as calculated by the two 
 methods.

 It will be noted that the maximum retardation by the Falkner 
 method is 76.1 per cent in District 3, as against 47.0 per cent in 
 the same district by the regular method, and that the minimum 
 is 57.6 per cent in District 10 as against 33.3 per cent in the 
 same district. Most of the other districts change order in amount 
 of retardation when the Falkner method is used. District 1 is 
 one point out ; District 2, two points out ; District 4 is three points 
 out ; District 5 remains the same. District 6 is one point out ; 
 District 7, three points ; Districts 8 and 9, each one point out. 
 The falling of District 4 from second place by the regular method

 logical Clinic, Vol. IV, No. 8, Jan., 1911, p. 213. 
 
RETARDATION IN PHILADELPHIA. 27 
 
 to fifth place by the Falkner method is due to the comparatively 
 low rate of elimination, 57.9 per cent. District 7 changes from 
 ninth place by the regular method to sixth place by the Falkner 
 method on account of its high rate of elimination, 72 per cent. 
 
 The Falkner method evidently gives a much truer measure of 
 an educational system if the elimination rate is not known, than 
 does the regular method. On the other hand, it fails to take into 
 consideration the entire number of pupils enrolled. It is valuable 
 as a supplementary method to check up results, and will often 
 make the retardation statistics clearer and uncover facts that 
 otherwise might pass unnoticed. 
 
 Summing up the results of this investigation we note that 
 to the pedagogical and psychological factors already recognized 
 as contributing to retardation, we must add a third, the sociological 
 factor. 
 
 From the psychological point of view, we see the need of 
 conditions which will make possible the giving of more attention 
 to individual pupils, not only in their school work, but in deciding 
 whether it is for the best interests of the pupil to be promoted or 
 left down, irrespective of the requirements for the average. 
 
 From the sociological point of view, we see the need of a 
 flexible course of study. The enrolment of the schools is made 
 up of various sociological units, which with their varying home 
 conditions, must be carefully scrutinized before a fixed course 
 of study is laid down for all. In the case of the negro, it seems 
 that the curriculum at present is entirely unfitted to his capabil- 
 ities. Apparently, the solution of this problem is to be found 
 only in organizing colored schools with a special curriculum. 
 
 Supervision, we have seen, may reduce the retardation to a 
 small extent by making wholesale promotions. This, however, is 
 an attempt to remove the effect without eradicating the cause. 
 On the other hand, by recognizing the psychological and sociologi- 
 cal factors in the problem and making adequate provision for them, 
 supervision may reduce the amount of retardation to a minimum.
