Alfred Binet
Also asked, when was the IQ test invented?
That's what Stanford psychologist Lewis Terman wanted us to believe when he introduced the American version of the IQ test in 1916. (This was quite the opposite intention of the test's original co-inventor, Alfred Binet. But that's a history lesson we'll return to another time.)
When was the first IQ test given?
The first 'real' IQ test. The first modern intelligence test in IQ history was developed in 1904, by Alfred Binet (1857-1911) and Theodore Simon (1873-1961).
What year did the IQ test start?
This adapted test, first published in 1916, was called the Stanford-Binet Intelligence Scale and soon became the standard intelligence test used in the U.S. The Stanford-Binet intelligence test used a single number, known as the intelligence quotient (or IQ), to represent an individual's score on the test.
