What Is a Good IQ Score for Kids by Age?

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.

What Is an IQ Score for Children?

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 Ranges for Kids: What Do They Mean?

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

Average IQ Scores by Age

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.

What’s Considered a “Good” IQ for a Child?

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.

Can a Child’s IQ Change Over Time?

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.

High IQ ≠ Guaranteed Success

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.

How Can Parents Support Their Child’s Intellectual Growth?

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

Final Thoughts

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.
