California Test of Mental Maturity (CTMM)
A wide-ranging group of intelligence tests that measure academic skills essential for school, such as learning, problem-solving and responding to new situations. Designed as a contrast to I.Q.
tests that measure genetically predetermined intelligence, CTMM measures five academic skills: logical reasoning, spatial relationships, numerical reasoning, verbal concepts and memory. CTMM tests yield a score for each skill, an overall score for nonlanguage skills, a second overall score for language skills and a total score for the entire test. Separate tests are given for each of six school-grade ranges, from kindergarten through senior year of college. A short version of the test—the California Short-Form Test of Mental Maturity—is also available.
