The Stanford–Binet Intelligence Scales (or more commonly the Stanford–Binet) is an individually administered intelligence test that was revised from the original Binet–Simon Scale by Alfred Binet and Théodore Simon. It is in its fifth edition (SB5), which was released in 2003.

The Stanford-Binet Intelligence Scales was a revised version of the Binet-Simon Intelligence test by Lewis Terman. He started his revision in 1910 and published it in 1916. [9] Terman used the 1908 version of the Binet-Simon test for his revision. [9] The most important addition is the replacement of mental age for the intelligence quotient (IQ ...
Alfred Binet (French:; 8 July 1857 – 18 October 1911), born Alfredo Binetti, was a French psychologist who together with Théodore Simon invented the first practical intelligence test, the Binet–Simon test. [2]
An intelligence quotient (IQ) is a total score derived from a set of standardized tests or subtests designed to assess human intelligence. [1] Originally, IQ was a score obtained by dividing a person's mental age score, obtained by administering an intelligence test, by the person's chronological age, both expressed in terms of years and months.
Modern intelligence tests, such as the current Stanford-Binet test, no longer compute the IQ using the above "ratio IQ" formula. Instead, the results of several different standardized tests are combined to derive a score.
Unlike Binet and Simon, whose goal was to identify less able school children in order to aid them with the needed care required, Terman proposed using IQ tests to classify children and put them on the appropriate job-track. He believed IQ was inherited and was the strongest predictor of one's ultimate success in life. [citation needed]
Instead, Stern proposed dividing an individual's mental age by their chronological age to obtain a single ratio. This formula was later improved by Lewis Terman, who multiplied the intelligence quotient by 100 to obtain a whole number. [7] Stern, however, cautioned against the use of this formula as the sole way to categorize intelligence.
