The Measurement of Intelligence: An Explanation of and a Complete Guide for the Use of the Standard Revision and Extension of the Binet-Simon Intelligence Scale

This is the landmark work that brought intelligence testing to America and shaped educational policy for over a century. Originally published in 1916, Lewis Terman's comprehensive guide presents the Stanford revision of the Binet-Simon Scale, the test that would eventually give the world the concept of IQ. Terman's work revolutionized how schools identified gifted students and those with learning disabilities, establishing the foundation for modern standardized testing. The book includes detailed instructions for administering the scale, statistical analysis of its reliability, and arguments for its application in educational placement. Reading this text today offers invaluable context for understanding ongoing debates about standardized testing, educational tracking, and the controversial history of measuring human intelligence. It remains essential reading for anyone seeking to understand where our current testing infrastructure came from, and why it remains so contested.
