The Stanford-Binet Intelligence Scale is a standardized test designed to measure human intelligence. Originally developed in the early 20th century by Alfred Binet and Théodore Simon, it was later revised by Lewis Terman at Stanford University. The test assesses various cognitive abilities, including reasoning, problem-solving, and memory, and is often used for educational placement and psychological evaluation. The scale provides an Intelligence Quotient (IQ) score, which helps to compare an individual's cognitive abilities to those of the general population. It is suitable for individuals aged 2 to adulthood and has undergone several revisions to improve its accuracy and relevance in measuring intelligence across diverse populations.
