Alfred Binet
Testing in the service of children
The French pioneer who created the first practical intelligence test.
techniques
A few modern philosophers assert that an individual's intelligence is a fixed quantity. We must protest and react against this brutal pessimism.
Who they were
Alfred Binet developed, with Theodore Simon, the first workable scale for measuring children's mental development, conceived to identify pupils who needed extra help rather than to rank human worth. His idea of mental age gave educators a practical tool while he himself warned against treating intelligence as fixed. He believed the mind could grow with the right support, and that assessment should serve teaching, not label children. His work quietly shaped a century of educational psychology.

Intelligence Testing
Alfred Binet built the first practical tests to identify children who needed extra help at school, introducing the idea of mental age as a way to compare a child's reasoning to what is typical for their years. He saw intelligence as something that grows and can be nurtured, not a fixed number stamped on a person for life.
