History
Each successive edition has been re-normed to compensate for the Flynn effect, ensuring not only that the norms do not become outdated, which is suggested to result in inflated scores on intelligence measures, but that they are representative of the current population (Flynn, 1984, 1987, 1999; Matarazzo, 1972). Additional updates and refinements include changes to the questions to make them less biased against minorities and females and updated materials to make them more useful in the administration of the test. A revised edition was published in 1974 as the WISC-R (Wechsler, 1974), featuring the same subtests. However, the age range was changed from 5–15 to 6–16.
