Which psychologist revised the 'Stanford-Binet Scale' for intelligence testing?
Detailed Explanation
📌 Core Theoretical Concept:
The 'Stanford-Binet Intelligence Scale' is a heavily revised and standardized version of the original Binet-Simon intelligence scale created by French psychologist Alfred Binet. In 1916, American psychologist Lewis Terman at Stanford University revised, expanded, and standardized the test for the American population. Terman popularized the use of the Intelligence Quotient (IQ) formula—multiplying the mental age divided by chronological age by 100. Because of this extensive revision, standardization, and psychometric enhancement at Stanford University, Lewis Terman is credited with the creation of the Stanford-Binet Scale. Other options like Alfred Binet created the initial 1905 scale, Spearman proposed the Two-Factor theory of intelligence, and Wechsler developed alternative widely-used individual intelligence scales like WAIS and WISC.
📊 Key Exam Points:
- Lewis Terman: A psychologist at Stanford University who revised the original Binet scale in 1916, resulting in the Stanford-Binet Scale.
- Alfred Binet: Developed the world's first formal intelligence test along with Theodore Simon in 1905 in France.
- Charles Spearman: Formulated the Two-Factor Theory of intelligence consisting of General (g) and Specific (s) factors.
- David Wechsler: Designed intelligence scales specifically for adults and children (WAIS and WISC) that feature verbal and performance subtests.
📖 Theoretical Reference: In educational psychology and psychometrics, the evolution of intelligence tests is a foundational topic. The transition from Binet's individual scale to Lewis Terman's standardized Stanford-Binet test laid the groundwork for modern psychological testing and educational placement strategies.

Deep pedagogical analysis and examination strategies:
Teacher eligibility tests (such as CTET, STET, and various state TETs) frequently test candidates on historical milestones in intelligence testing. A common point of confusion among aspirants is distinguishing between the creator of the original scale and the creator of the Stanford-Binet version. While Alfred Binet pioneered intelligence testing to identify students needing special assistance in French schools, Lewis Terman adapted and normed it for American contexts at Stanford University, giving birth to the Stanford-Binet test and formalizing the IQ calculation method. Understanding these distinctions helps candidates tackle direct factual questions accurately. Furthermore, teachers should appreciate how standardized tests influenced modern inclusive education and differentiated instruction by recognizing varied cognitive levels among students.
