Understanding IQ scores and how they relate to age can be confusing, especially for parents and educators. If you’re wondering what the average iq in USA for a 12-year-old boy—or children aged 11, 13, and 14—this guide will break it down for you.
What Is an IQ Score?
IQ, or Intelligence Quotient, is a measure of a person’s cognitive abilities compared to others in their age group. The average IQ score is set at 100, with most people falling between 85 and 115.
How Is IQ Calculated for Children?
IQ tests for children are age-adjusted, meaning a 12-year-old’s performance is compared to other 12-year-olds, not adults. This ensures fairness since cognitive abilities develop over time.

The average IQ for a 12-year-old boy is 100, the same as the general population. However, scores typically range between 85 and 115, which is considered the “normal” range.
Factors That Influence a 12-Year-Old’s IQ
Several factors can affect a child’s IQ, including:
- Genetics – Inherited traits play a role in cognitive abilities.
- Education – Quality of schooling and learning opportunities.
- Environment – Nutrition, home life, and mental stimulation.

Average IQ for an 11-Year-Old
Like 12-year-olds, the average IQ for an 11-year-old is 100, with most scoring between 85 and 115. At this age, children are developing critical thinking and problem-solving skills, which IQ tests measure.

By age 13, cognitive abilities become more refined. The average IQ remains 100, with scores typically between 85 and 115.
How IQ Tests Differ for Teens
Teen IQ tests may include more complex problem-solving and abstract reasoning questions compared to tests for younger children.

At 14, the brain is still developing, but reasoning skills are more advanced. The average IQ is still 100, with most teens scoring within the 85-115 range.

While IQ is generally stable, factors like education, trauma, or mental health can cause slight fluctuations. However, drastic changes are rare.
