In giving a group test it is practically always necessary to obtain the identifying information called for on the title page before the booklets are opened or turned over. There is a distinct tendency for candidates to try to glance at the pages which follow unless specific directions are given as the papers are distributed that this must not occur. The procedure in giving Mentimeters 2 to 10 to people who can understand and even read English is very little different from the procedure to be used with the foreign-language-speaking groups. Mentimeters 11 to 15 cannot be given as group tests because of the great amount of writing which this would entail. Group tests are most efficient when candidates are required to do nothing other than check the correct answers without having to write anything. Mentimeters 16 to 30 may be given as individual examinations, although they are planned as group examinations and the results obtained from their use as group examinations will be superior to the results obtained from their use as individual examinations. In giving all of these tests it is very important that the printed forms prepared by the publishers be employed and that the directions which follow be carefully observed. The stencils furnished with the printed test booklets make it possible for a clerk of average mental capacity to mark and score the results of these examinations with great rapidity and with just as much accuracy as could be obtained by specialists working without such stencils. These stencils and the group method make psychological examinations economical of administration. The list of Mentimeter tests is as follows: THE MENTIMETER TESTS TEST FOR INFANTS 1.
