The purposes of this study are: (1) To construct a scale for the measurement of general mental ability, such scale being: (a) suitable primarily for administration to the pupils in grades 4, 5, 6, 7, and 8 of the elementary school, (b) capable of being administered to groups of at least 50, (c) so constructed that the scoring is both rapid and, as far as possible, free from the error of the personal factor, (d) built upon the general plan for an Absolute Point Scale outlined by the writer (see Ref. 10). Such construction would involve the “validation” and “graduation” of the tests, the determination of the probable error of a determined measure of general mental ability, etc. (2) To investigate the correlation of the mental abilities tested by the scale.
