History of IQ Tests

In 1905 the French psychologists Alfred Binet and Théodore Simon created the first modern intelligence test. The Binet-Simon test, as it was called, was a great success and spread it around Europe and America.

Years later, the German psychologist William Stern coined the term "IQ", an acronym for Intelligenz-Quotient, which was a score derived from a standardized test (psychologist-administered) designed to access one’s intelligence.

Nowadays there are several standardized tests, where the Wechsler IQ tests are probably the most widely used IQ tests worldwide.

Just for reference, you can check the table bellow that shows the IQ classification based on the Wechsler Adult Intelligence Scale—Fourth Edition (WAIS–IV):

120–129 Superior
