5-12 years · Average IQ: 100 (age-normalized)
IQ testing in children measures cognitive development relative to age-matched peers. The average IQ for children is 100 by definition, as IQ scores are normalized within each age group. However, the reliability of IQ testing increases with age, and scores before age 6 should be interpreted cautiously.
IQ scores in children are age-normalized, meaning 100 is always average for any given age
Test-retest reliability improves significantly after age 6
Gifted identification typically uses a threshold of IQ 130+, though this varies by program
Environmental factors like nutrition, education quality, and home environment significantly influence childhood IQ development
Early reading ability, large vocabulary, and intense curiosity are common indicators of high childhood IQ
The Flynn Effect suggests average IQ scores have been rising approximately 3 points per decade across generations
In children, fluid intelligence (pattern recognition, novel problem-solving) develops rapidly and is the primary focus of childhood IQ tests like the WISC-V. Crystallized intelligence (accumulated knowledge) is still developing and depends heavily on educational exposure.
Childhood IQ tests (WISC-V, Stanford-Binet 5) are administered individually by trained psychologists, not online. Group-administered tests in schools are screening tools, not diagnostic. Test anxiety, attention span, and rapport with the examiner can all affect results. A single test score should never be used as the sole basis for educational decisions.
A normal IQ for a 7 year old is 100, the same as any age. IQ scores are standardized so that 100 is always the average for each age group. Scores between 90-109 are considered average.
Yes. IQ scores in children can shift by 10-15 points or more between testings, especially before age 8. Scores generally stabilize more after age 10, though significant changes are still possible due to environmental factors, education, and neurological development.
IQ testing becomes significantly more reliable after age 6, with test-retest correlations above 0.90 by age 8-10. Testing before age 4 has limited predictive validity for adult IQ.
