Measurement of Intelligence

Overview

Measurement of intelligence is a foundational topic in Child Development and Pedagogy that directly connects psychological theory to classroom practice. For CG TET, you must understand how intelligence is quantified, the major tests used, and—most importantly—how teachers should interpret and apply these measurements in educational settings.

This topic typically appears as 1-2 questions in the exam, often testing your knowledge of IQ calculation, famous intelligence tests and their developers, or the limitations and proper use of intelligence testing in schools. Questions may also link this concept to inclusive education, asking how teachers should respond to children with varying intelligence levels without labelling or discrimination.

Mastering this topic requires you to move beyond rote memorisation of test names. Focus on understanding the concept of Mental Age versus Chronological Age, the IQ formula, classification of intelligence levels, and the pedagogical implications—especially the caution against using IQ scores to permanently categorise children.

Key Concepts

• **Intelligence Quotient (IQ)** is a numerical score representing an individual's cognitive ability relative to their age group. It is not a fixed, unchangeable trait but can be influenced by environment and education.
