In the early 20th century, a certain European country played a crucial role in the emergence of cognitive evaluation methods. The Binet-Simon examination, crafted by psychologists A. Binet and T. Simon in 1905, took centre stage. Their ingenious creation set out to pinpoint pupils necessitating supplementary educational aid. Commissioned by an educational entity, Binet and Simon aspired to devise an instrument adept at impartially gauging a youngster's mental capabilities, surpassing the capacities of conventional methodologies.
