The Stanford-Binet Test traces its roots to the Binet-Simon Scale, a French device for identifying levels of intelligence, originally developed in an attempt to quantify human intelligence. The Binet-Simon Scale was developed by Alfred Binet and his student Theodore Simon.
Universal Nonverbal Intelligence Test The Universal Nonverbal Intelligence Test (Bracken & McCallum, 1998) is a set of individually administered tasks designed to measure the cognitive abilities of children and adolescents (ages 5–17) who may be at a disadvantage in responding to traditional verbal or language-loaded tests.
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.
