Alfred Binet

Alfred Binet (1857 — 1911) was a French psychologist known for devising a mental age scale. It measures the mental performance of a student in relation to the group of students of the same physical age group. He also worked with psychiatrist Theodore Simon (1873 — 1961) for a pioneering system of intelligence test known as Binet-Simon test or simply Binet test. The scale on which this test performed is called Binet-Simon scale.
