Booklet, Examiner's Guide for the Psychological Examination of Recruits Revised by Direction of the Surgeon General of the Army and Printed by the Medical Department U.S.A.


During World War I, large numbers of men entered the armed forces. To sort out those deemed unsuited for combat and to select those of particular promise, psychologists working for the office of the Surgeon General of the Army developed a series of tests. Recruits who could read English took a group intelligence test known as the Army a (later Army Alpha). Those who could not read English – some of whom could not speak it either - took a group test called the Army b (later Army Beta). Instructions in it were given in pantomime. Those that did not pass either test might be examined individually. This publication from 1917 describes procedures for administering the Army a, the Army b, and individual tests.
