Alfred Binet (July 11, 1857 – October 18, 1911) was a French psychologist who invented the first usable intelligence test, known at the time as the Binet test and today referred to as the IQ test. His principal goal was to identify students who needed special help in coping with the school curriculum. Along with his collaborator Théodore Simon, Binet published revisions of his intelligence scale in 1908 and 1911, the last appearing just before his death.
A further refinement of the Binet-Simon scale was published in 1916 by Lewis M. Terman, from Stanford University, who incorporated William Stern's proposal that an individual's intelligence level be measured as an (I.Q.). Terman's test, which he named the Stanford-Binet Intelligence Scale, formed the basis for one of the modern intelligence tests still commonly used today. They are all colloquially known as IQ tests.
