The re-standardization of a point performance scale

Abstract

A preliminary report on the standardization of a point performance scale (described in J. Appl. Psychol., December, 1925). The 8 tests of the 1925 scale plus the Porteus Maze Test were used on 1100 children. The materials and procedure of the tests are described in detail. The time for giving the scale varies from 35 to 90 minutes. Tables are presented which contain a combined point scale, values for converting point scores into years and months of mental age, and values for determining the point value of any score. Between Stanford-Binet IQ's of 119 subjects and the IQ's from this scale, the P.E. of measurement was 4.92; between Kuhlmann-Binet IQ's of 76 subjects and their IQ's from this scale, 4.95.
