    Measuring Intelligence

    By the late 1910s, educational experts in the United States had developed a series of intelligence quotient (IQ) tests for measuring human intelligence. IQ tests became popular with school reformers who wanted to track and stream pupils by intelligence to make school systems more differentiated and efficient, and with eugenicists — including the members of the Canadian National Committee for Mental Hygiene—who looked for ways to identify and control so-called ‘feebleminded’ adults and children.
