Binet's Contribution to Measures of Intelligence

In 1904, the French Ministry of Education tasked Alfred Binet with identifying students who struggled to learn through conventional classroom instructions.

To identify the students, Binet and his student, Theodore Simon, designed an assessment. They created a 30-item test, including tasks ranging from simple commands, like touching one's nose or ear, to more complex tasks, such as drawing designs from memory and defining abstract concepts.

The test, later known as the Stanford-Binet, remains widely used to measure intelligence.

Binet introduced the concept of mental age, which compares an individual's cognitive abilities with those typical of their age group.

According to him, a child's mental age might align with, exceed, or fall short of their chronological age or actual age. For example, a bright child might solve problems typical of older children.

Comparing mental age to chronological age helps determine if a child is ahead, on track, or behind in cognitive development.

This approach allows educators to identify students who may benefit from additional support or specialized instructions.
