The intelligence test used most often today are based on the work of a Frenchman, Alfred Binet. In 1905, Binet was asked by the French Ministry of Education to develop a way to identify those children in French schools who were too "mentally deficient(不足的)" to benefit from ordinary schooling and who needed special education. The tests had to distinguish those who were merely behind in school from those who were actually mentally deficient.
The items that Binet and his colleague Theophile Simon included on the test were chosen on the basis of their ideas about intelligence. Binet and Simon believed intelligence includes such abilities as understanding the meaning of words; solving problems, and making commonsense judgements. Two other important assumptions also shaped Binet’s and Simon’s work: (1) that children with more intelligence will do better in school and (2) that older children have a greater ability than younger children.
