Binet and Simon's primary intention in designing their intelligence test was to identify children likely to have difficulty learning in regular school classes. This goal was driven by their concern for the educational needs of children, especially those who might not succeed within the traditional educational system. The test was intended to help educators determine which students required additional support or different educational strategies, ultimately to facilitate better learning outcomes.

The focus was on practical application, specifically aimed at supporting children in an educational setting, rather than merely measuring inherited potential, distinguishing types of intelligence, or assessing a broad spectrum of adaptive behaviors. By concentrating on identifying academic struggles, Binet and Simon laid the groundwork for intelligence testing as a tool for education and public policy.
