Columbia Mental Maturity Scale

Abstract

The third revision of this individual test of “general reasoning ability,” for children between 3½ and 10 years of age, is made up of 95 cards on which are printed sets of pictures and symbols. Three of the cards are sample items used for instruction. On each card some categorical concept is represented by the pictures or symbols. For each, the child picks out the exception to the depicted concept. Instructions are given orally and the child's score is determined from his overt response. Hand scored. Kit and manual $50.00. Individual record form $4.00 pkg/35. No time limit. Approximately 15 to 20 minutes.
