History of IQ test

IQ test measure mental capacitySome children are given an intelligence quotient (IQ) test in order to test their mental ability and determine what they can handle in their academia.

However, many people may not realize the history of the IQ test. According to IQTest.com, British scientist Sir Frances Galton was one of the first people to be recognized for measuring people’s IQ after he used research to compare individuals’ awards and accomplishments.

Following Galton’s initial research, a French psychologist named Alfred Binet developed a test that accurately predicted academic success for children. This project was brought on after the French government asked him to come up with a measure of which children would have problems in their curriculum.

 Henry Goddard, who was the director of a school for the disabled, took Binet’s test to the U.S., where he translated it to English and used it for people who were considered to be mentally retarded. The website suggests that an American psychologist named Lewis Terman used the test and adapted it to adults.

Finally, David Wechsler came up with a procedure that relates an individual’s score to the normalization sample, which determines how the test taker matches up against the norm.
