IQ tests for children can offer early insights into learning potential, problem-solving skills, and cognitive development. But what’s considered a “good” IQ score for kids at different ages? In this guide, we explain how IQ works in children, the average range by age, and how to interpret the results fairly and constructively.
IQ (Intelligence Quotient) is a standardized score derived from tests designed to measure reasoning, memory, processing speed, and verbal/non-verbal abilities. IQ scores are age-normed, which means a 7-year-old scoring 100 is performing at the average level for all 7-year-olds.
Most modern IQ tests (like the WISC-V or Stanford-Binet) use a mean score of 100 and a standard deviation of 15.
IQ Score | Category | Interpretation |
130+ | Gifted or highly gifted | Top 2%; may benefit from enrichment or accelerated programs |
115–129 | Above average | Strong reasoning, fast learner |
85–114 | Average | Typical intellectual development |
70–84 | Below average | May struggle in some academic areas |
Below 70 | Possible intellectual disability | Needs further evaluation and support |
Age | Average IQ Range |
2–4 | 90–110 |
5–7 | 90–110 |
8–10 | 95–115 |
11–13 | 95–115 |
14–16 | 100–115 |
These values represent age-adjusted norms. That means a 5-year-old with an IQ of 100 is just as average (intellectually) as a 15-year-old with the same score.
A “good” IQ score depends on context:
IQ isn’t a fixed measure of worth. It’s a snapshot of how a child thinks and processes information compared to peers.
Yes. While core cognitive abilities are relatively stable, environment, education, nutrition, emotional well-being, and support all influence IQ-related performance—especially in early childhood. A 6-year-old with an IQ of 90 could score 110 at age 9 with proper support.
Even children with high IQs may struggle if they aren’t emotionally supported or intellectually engaged. Emotional intelligence (EQ), curiosity, grit, and social skills are equally vital for long-term success.
Read together and ask open-ended questions
Use educational puzzles and games
Allow unstructured playtime to encourage creativity
Avoid labeling them as “smart” or “slow”—praise effort instead
Support their strengths and patiently guide their weaknesses
IQ tests can provide helpful insights—but they’re just one piece of the puzzle. Whether your child scores 95 or 135, the most important factor is how they are nurtured, challenged, and encouraged to explore their full potential.
