The Differential Ability Scales (DAS) is a nationally normed (in the US), and individually administered battery of cognitive and achievement tests. Currently into its second edition (DAS-II), the test can be administered to children ages 2 years 6 months to 17 years 11 months across a range of developmental levels.

Wechsler Adult Intelligence Scale (WAIS) The WAIS was initially introduced in 1955 as an alternative to the Binet Scale to measure intelligence in adults. By the 1960's, the WAIS had surpassed even the newer version of the Binet Scale, the Stanford-Binet Intelligence Scales, as the preeminent tool for testing adult intelligence levels.
The Wechsler Individual Achievement Test, or WIAT, is a test that measures a person's intelligence. The test can be taken by children and adults from age four to 85. Children and adolescents are often given the WIAT in order to identify areas where they may struggle or excel at in school.
The Woodcock-Johnson Tests of Cognitive Abilities is an intelligence test series (often referred to as IQ test). First developed in 1977 by Richard Woodcock and Mary Johnson, the Woodcock-Johnson test was revised in 1989 and 2001, and today’s most recent version is known as the WJ-III.
