1 Stanford-Binet was given in June to unselected experimental groups totaling over 1 ,000 men ; hence the marked reduction in per cent of E grades. 



The number of low mental ages reported was low in May and June, while the individual 

 examining was not thoroughly under way; it was extremely high hi October in relation to total 

 because the influenza epidemic prevented group examinations; and high in August on account 

 of the large negro draft (Table G).

Recommendations for discharge were made in less than one-half of one per cent of all 

 men examined. Recommendations for service organizations and development battalions in- 

 clude another 1. 25 per cent. In all, 1.75 per. cent were considered unfit for regular military 

 service. 



Table 8 summarizes the details of individual examining and recommendations, and shows 

 considerable variations from camp to camp. These are explainable by referring (1) to the 

 nature of the draft received (number of illiterates, foreigners, and negroes, mental level of the 

 district represented and the standards of the local draft boards) and to the fact that ehmination 

 by other camp examining boards was made at some stations before, and at others after, the 

 psychological examination took place; (2) to differences in interpretation and application of 

 standards by different staffs and individual examiners; (3) to differences in attitude of the med- 

 ical boards at different stations, toward recommendations of the psychological staff; (4) to 

 differences in number and kind of cases referred by commanders for mental examinations 

 (Table 8).
