Equally lacking in correlation is the case of the group of 

 seventeen in all, whose I.Q.'s fell between 96 and 105, 

 i.e., the normal group. Only three of these were rated 

 by teachers as belonging to the middle fifth of their 

 classes, five were rated as belonging to either the lowest 

 or next to the lowest fifth of the class, and nine were 

 placed in either the highest or next to the highest fifth of 

 the class. In the case of two pupils who made a very 

 high score that fell between 126-130 in the Binet Test, 

 one was rated as belonging to the highest fifth of his 

 class and the other was rated as belonging to the lowest 

 fifth of his class. 



The lack of correlation in the instances noted above be- 

 tween the judgments of teachers and the Stanford Re- 

 vision of the Binet-Simon Test for intelligence indicate 

 that in this instance, at least, doubt may be reasonably 

 expressed on the reliability of either the results of the 

 tests or the judgments of the teachers. 



A STUDY OF TEACHERS' JUDGMENTS AFFECTING ALL THE PUPILS 

 FROM GRADES ONE TO TWELVE INCLUSIVE, EXPRESSED IN 

 TEEMS OF INDUSTRY, SCHOLARSHIP AND INTELLIGENCE, 

 AND THE DISTRIBUTION OF THE PUPILS IN TERMS OF IN- 

 TELLIGENCE TESTS EXPRESSED IN INTELLIGENCE QUOT- 

 IENTS. 



Our study so far seems to indicate that there is little 

 or no correlation between the judgments of teachers and 

 intelligence tests, when applied to pupil mental ability. 

 Since either one or the other or both must be justified, 

 and since it appears that in the process of judging so 

 far a number of teachers have asked to have " mental 

 ability" defined, it was decided to extend the study and 

 organize it so as to direct the attention of teachers to 

 intelligence as differentiated from other qualities often 

 confused with it in the attempt to form a judgment. In 

 this study the Intelligence Quotients were obtained in 

 the first and second grades by the Stanf ord-Binet Tests ; 

 in the other grades, three to twelve inclusive, they were 

 computed from the results obtained by giving the Otis 

 Intelligence Tests in grades seven to twelve and the 

 Dearborn Tests in grades three to six. The teachers ' at-
