History of IQ Testing

IQ Tests are primarily a product of the 20th Century . While most textbooks provide a brief history, starting with Binet, a few websites do the same.

The ACE Intelligence Website at http://www.aceintelligence.com/detailed_history_of_iq.php, gives a fairly detailed history of IQ testing following various individuals important in test development including a few prior to Binet.

The IQ Test Center at http://www.iqtest-center.com/history.php provides a brief history of testing similar to many textbooks.

Classics in the History of Psychology (http://psychclassics.yorku.ca/author.htm) have a number of the original articles on intelligence testing. They include:
