    tribution of Salt Lake City children (140) is taken as a stand- ard. E. D. Jennings, in a survey as yet unpublished, found that the average retardation of the Salt Lake City school children, as given by Cubberley, was a little greater than that of Dallas, a little less than that of San Antonio and about equal to that of Austin. It is accordingly a fairer standard to use than one drawn from the far North or East. Considering grade 2a to run from grade 1.5 to 2.0, grade 2b from grade 2.0 to 2.5, etce., it is found from the Salt Lake City age-grade distribution that the median 814-year-old is in attendance upon grade 2.23, etc., as shown herewith. } Age Median Grade Le ROE eats gee OAPs ba ch 1.31 Se AOR are 18 REAR oes ode ee 2.23 Va hip CUAL NOE LD as orc PRA HO ea ab 10 Be ee OE he era 3.97 1B es Sang ck Wi eR care 4.70 Rs Meee Ganon oN re as! 5.57 1 2A Ran RR A | PE SEO 6.49 51 OP i Smet che Oe th Ga RMR NER | rire Sk SPR aM IS dey ma 8.19 Ga heise ee Os ere 9.23 cae See AMRRCET AS Re Te earn 10.21 1 1: RARE eae SS earn Beet” 14021 It will be noticed that the ‘‘normal,’’ i. e., the average, child accomplishes the six grades from grade 2 to grade 8 in seven years. Retardation of the J uvenile Training School boy is eal- culated in terms of years as in the case of all the other measures and not in terms of grades; e. g., a 11.5 year old child who is in grade 3.97 (i. e., not quite to the middle of grade 4) 1s re- tarded .73 of a grade but 1.00 year. The norms show that from age 15 on, a grade seems to be made each year. This, however, is probably not the case, but only appears so, due to the elimination of the duller (older) pupils. The erade aver- ages, of course, are averages only for those who attend school, and these undoubtedly constitute for ages from 15 on, a select group. It should, therefore, be kept in mind that the Juvenile Training School boy is being compared to children of his own. age who are attending school, and not to children of his own
