Who revised the 'Stanford-Binet Scale' for intelligence testing?
Detailed Explanation & Solution
📌 Core Theoretical Concept:
The 'Stanford-Binet Intelligence Scale' was revised by American psychologist Lewis Terman at Stanford University in 1916. Originally, the first practical intelligence test was created by Alfred Binet and Théodore Simon in France in 1905. Since the original Binet-Simon scale was tailored for French children and unsuited for American demographics, Professor Lewis Terman extensively revised, standardized, and adapted it for American populations at Stanford University. This revised version became famously known as the Stanford-Binet Scale. Terman was also instrumental in popularizing the concept of Intelligence Quotient (IQ) using William Stern's formula (Mental Age divided by Chronological Age multiplied by 100), making it a gold standard in psychological testing and educational psychology.
📊 Key Exam Points:
- Alfred Binet (Option a): Developed the world's first practical intelligence scale in 1905 with Simon, but did not perform the Stanford revision.
- Lewis Terman (Option b - Correct Answer): Standardized and revised Binet's test at Stanford University, creating the benchmark Stanford-Binet test.
- Wechsler (Option c): David Wechsler designed distinct intelligence scales for adults and children (WAIS and WISC), emphasizing verbal and performance subtests.
- Spearman (Option d): Charles Spearman proposed the Two-Factor Theory of Intelligence consisting of General (g) and Specific (s) factors.
📖 Theoretical Reference: The evolution of intelligence testing is a core domain in child development pedagogy. Intelligence Testing and Measurement highlights Terman's crucial role in standardizing psychometric tools for educational assessment in American psychology.

Deep Pedagogical Analysis:
Teacher eligibility tests (such as CTET, UPTET, Super TET, and KVS) frequently test candidates on the historical milestones of intelligence testing. A common point of confusion for aspirants is distinguishing between the creator of the first test (Alfred Binet) and the person who revised and standardized it for broader application (Lewis Terman at Stanford). Understanding this distinction helps in solving matching questions and factual mcqs accurately. Terman's work also laid the groundwork for identifying gifted children and classifying levels of intellectual disability, which is highly relevant for inclusive education and differentiated instruction in modern classrooms. Mastering these foundational facts ensures high accuracy in pedagogy sections.
