THE ARMY INTELLIGENCE TESTS seven letter ratings, each letter being the equivalent of certain numerical points. The letter grades, the numerical equivalents, and significance of each are as follows: A Very Superior Intelligence: 135 to 212 points. Men who graded "A," when pos sessed of other necessary qualifications, were regarded as "high officer type." From three to five per cent of the drafts were "A" grade men. B Superior Intelligence: 105 to 134 points. Men who graded "B" frequently possessed other sterling qualities which qualified them for the commissioned officer type. In actual practice an occasional "B" grade officer outranked in efficiency an "A" grade officer, but only when other necessary qualities were pronounced in the former and relatively lacking in the latter. The "B" grade indicates high type of noncommissioned material. C+ High Average Intelligence: 75 to 104 points. This grade indicates good noncommissioned officer material, rarely material for the commissioned rank. C Average Intelligence: 45 to 74 points. Good private type with fair noncommissioned material. C- Low Average Intelligence: 25 to 44 points. Ordinary private material. D Inferior Intelligence: 15 to 24 points. Men of this grade are slow, illiterate, and as a rule make only fair soldiers. D- Very Inferior Intelligence: 0 to 14 points. This grade of intelligence repre sents the mentally unfit, the incompetent who are recommended for either development battalions, special service organizations, or for discharge. BETA.-Like ALPHA this is a group test but is intended for illiterates and foreigners. Knowledge of English is not essential in taking this test since the instructions are given by the examiner by means of demonstrations. This 673 set of tests parallels ALPHA in the method of scoring, the variety of grades of intelligence classification, and in the objective character of the results. A workable correlation exists between ALPHA and BETA so that an "A" grade in the former is roughly equivalent to an "A" grade in the latter. INDIVIDUAL TESTS.-Individual tests are given to those who fail or make a very low score in BETA after having failed in ALPHA. Two forms of individual examinations are used for those who understand English, namely, the Yerkes-Bridges Point Scale and the Stanford revision of the Binet Scale. By means of the Performance Scale illiterates in English are examined. The time required to give an individual examination varies from ten minutes to an hour. It is obvious from the above that the variety of tests covers every case and that, therefore, a complete mental classification of all recruits is made possible. Major R. M. Yerkes, lately chief of the Division of Psychology, gives the following summary of the results of psychological examining in the various cantonments where this service was organized: "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 1, 1919. Of this number, about 41,000 were commissioned officers. More than 83,000 of the enlisted men included in the total had been given an individual examination in addition to the group examination for literates, for illiterates, or both. "Between April 27 and November 30, 1918, 7749 (0.5 per cent) were reported for discharge by psychological examiners because of mental inferiority. The number of recommendations for assignment to labor battalions because of low grade intelligence was The recruits marched into the examining room, were seated, and each supplied with a pencil and examination booklet by orderlies who supervised the group during the examination and upon its completion collected papers and pencils. As soon as the group was seated and supplied with the necessary examining material, the following general directions were given by the examiner: "Attention! The purpose of this examination is to see how Individual examination.-The manikin test, which the recruit is trying to put together, is one of the Performance tests given to those who have made a low score in the preceding group tests well you can remember, think, and carry out what you are told to do. The aim is to find out what you are best fitted to do in the Army. "Now, in the Army a man often has to listen to commands and then carry them out exactly. I am going to give you some commands to see how well you can carry them out. Listen closely. Ask no questions. Do not watch any other man to see what he does. 1 The ALPHA examination comprises eight tests given to recruits in groups numbering 500 as a desirable maximum. In practice the actual number probably did not exceed 200 as an average. Each such group could ordinarily be examined in somewhat less than one hour. THE ARMY INTELLIGENCE TESTS "Look at your papers. When I call 'Attention,' stop instantly whatever you are doing and hold your pencil up -so. (Examiner illustrates by raising his pencil.) Don't put your pencil down to the paper until I say 'Go.' Listen carefully to what I say. Do just what you are told to do. Remember, wait for the word 'Go.'" Of the eight tests included in the ALPHA examination a limited amount of each of tests 1, 3, 4, 6, and 7 is given here. 675 "Attention! 'Attention' always means 'Pencils up.' they keep better time Look at the circles at 1.

When I say 'Go' make a figure 2 in the space which is in the circle but not in the triangle or square, and also make a figure 3 in the space which is in the triangle and circle, but not in the square.-Go!" (Allow not more than 10 seconds) 7. ABCDEFGHIJKLMNOP "Attention! Look at 7. When I say 'Go' cross out the letter just after F and also draw a line under the second letter after I.-Go!" (Allow not more than 10 seconds) "Attention! Look at 11.
