Intelligence Quotient (IQ) Testing – where did it come from?
Two psychologists named Alfred Binet and Theodore Simon created the first Intelligence Scale in 1905. The French government had commissioned this test to assess, which students would likely succeed or fail in the French school system. In 1930, Lewis Terman made revisions to this original assessment and renamed it the Intelligence Test. This was the first time in history that an intelligence quotient to measure a child’s mental age against their chronological age.
