Summary:

"The Arthur adaptation of the Leiter International Performance Scale is, in principle, a non-verbal Binet scale for young children. Its main advantages are: (1) it reaches down to lower chronological age levels than the other performance scales, (2) the tests lowest in the scale are tests of ability to learn rather than tests of acquired skills or material already learned: the first five tests are given credit as passed if the subject is able to perform the task without demonstration or help during any one trial, no matter how many previous trials have been given and without regard to the amount of demonstration and help it has been necessary to give during previous trials; (3) every test of the scale is given without a time limit; and (4) the entire scale is given, as it was standardized, without any verbal directions. The need for restandardization of the original Leiter scale was felt when it became evident that the Leiter norms for "Caucasian" children were too high to enable the average middle-class American child to earn a score that adequately represented his level of ability. The need for the reorganization of the scale was felt in order to get rid of certain tasks demanding acquired skills such as telling time, and to eliminate the timing of any of the tests to facilitate the use of the scale with spastics. During the standardization of the Arthur Adaptation of the Leiter scale, more help has been given to the subject to insure comprehension of the task than was indicated in the original Leiter scale. With only four tests at each age level, an accidental success or failure has too much effect on the final score. It is because of the small number of tests at each chronological age level that the Arthur Adaptation of the Leiter scale is supplemented with the Revised Form II of the Point Scale of Performance Tests (3) to increase the reliability of the rating obtained. The increase in time needed for examination on both scales is important in itself, as the subject is under observation for a longer period under controlled conditions, and has more opportunity to demonstrate the average intellectual level of his reaction pattern"--Introduction.
