animation of school children correlate .94 to .97. Results 

 of one-half of the scale compared with the other half 

 correlate .94 to .96. An abbreviated form of the Stan- 

 ford-Binet examination consisting of two tests per year 

 was used extensively in the army. The results of this 

 abbreviated scale correlate .92 with those obtained by 

 use of the complete scale. 



For the Point Scale examination the measures of re- 

 liability are practically the same as for the Stanford- 

 Binet. 



A Performance Scale examination prepared especially 

 for military use consisted of ten tests. Results for the 

 several tests of the scale correlate with Stanford-Binet 

 results, .48 to .78. Five of the ten tests yield a total score 

 which correlates .84 with the Stanford-Binet score. The 

 same five tests correlate .97 with the results of the entire 

 scale. 



Summary of Results. After preliminary trial in four 

 contonments psychological examining was extended by 

 the War Department to the entire army, excepting only 

 field and general officers. To supply the requisite per- 

 sonnel, a school for training in military psychology was 

 established in the Medical Officers' Training Camp, Fort 

 Oglethorpe, Georgia. Approximately one hundred offi- 

 cers and more than three hundred enlisted men received 

 training at this school. 



The work of mental examining was organized finally 

 in thirty-five army training camps. A grand total of 

 1,726,000 men had been given psychological examination 

 prior to January i, 1919. Of this number, about 41,000 

 were commissioned officers. More than 83.000 of the en- 

 listed men included in the total had been given individual 

 examination in addition to the group examination for 

 literates, for illiterates, or both. 



Between April 27 and November 30, 1918, 7,749 (0.5 

 per cent.) men were reported for discharge by psychologi- 

 cal examiners because of mental inferiority. The recom-
