The 2014 revision of the WISC was intended to reflect modern theoretical conceptions of intelligence and the current population of children in the United States, which is than it was when earlier versions of the WISC were developed.

The Wechsler Intelligence Scale for Children (WISC) is an individually administered intelligence test for children between the ages of 6 and 16. It is more effective than it was when earlier versions of the WISC were developed.

The Fifth Edition (WISC-V; Wechsler, 2014) is the most recent version. The original WISC (Wechsler, 1949), developed by the Romanian-American psychologist David Wechsler, Ph.D., was an adaptation of several of the subtests that made up the Wechsler–Bellevue Intelligence Scale (Wechsler, 1939), but also featured several subtests designed specifically for it.
