The Wechsler Adult Intelligence Scale (WAIS) intelligence quotient An intelligence quotient, or IQ, is a score derived from one of several different standardized tests designed to assess intelligence. The term "IQ", from the German Intelligenz-Quotient, was devised by the German psychologist William Stern in 1912 as a proposed method of scoring early modern children's intelligence tests such as those (IQ) tests are the primary clinical instruments used to measure adult and adolescent intelligence.[1] The original WAIS (Form I) was published in February 1955 by David Wechsler David "Wex" Wechsler was a leading American psychologist. He developed well-known intelligence scales, such as the Wechsler Adult Intelligence Scale (WAIS) and the Wechsler Intelligence Scale for Children (WISC), as a revision of the Wechsler-Bellevue Intelligence Scale.[2] The fourth edition of the test (WAIS-IV) was released in 2008 by Pearson Pearson plc is a London-based education and media conglomerate.

He is best known as the inventor of the Stanford-Binet IQ test. He was a prominent eugenicist and was a member of the Human Betterment Foundation. He was also served as president of the American's Stanford-Binet Intelligence Scales The development of the Stanford-Binet Intelligence Scales initiated the modern field of intelligence testing. The Stanford-Binet test started with the French psychologist Alfred Binet, whom the French government commissioned with developing a method of identifying intellectually deficient children for their placement in special education programs were less cautiously developed than previous versions, Form I of the WAIS surpassed the Stanford-Binet tests in popularity by the 1960s.[2]
Wechsler defined intelligence as "The global capacity of a person to act purposefully, to think rationally, and to deal effectively with his/her environment."[4]
