, FIGURE V — Medians OF Both Tests. Lower line represents visual 

 vocabulary scores. Upper line shows understanding of sentences. 



For both tests the steps decrease in amount toward the upper 

 grades. The step from grade 7 to grade 8 is about half that from 

 grade 3 to grade 4 in visual vocabulary and about one-fourth in 

 understanding of sentences. The average step for the visual 

 vocabulary test is .79, and for the understanding of sentences 

 it is .71. 



What is true of the medians for the cities as a whole is, in a 

 general way, true for each city taken separately. In the entire 

 set of tests, there are 83 grade intervals in the visual vocabulary 

 test, and 83 in the understanding of sentences. In the former, 

 there are just 8 cases in which a grade shows a score higher than 

 that of a higher grade, and in the latter there are 11 cases. These 

 variations from the rule are doubtless due to the conditions in the 

 several cities where the higher grades do not continue to improve 

 in reading abihty as they should. 



Absence of Proper Grade Progression 



While the increase from grade to grade is the common fact, 

 the small amount of this increase in many cases is very striking.
