70
Extremely Low · Below the 2nd percentile

An IQ score of 70 places you in the borderline intellectual functioning of cognitive ability. This means you scored as well as or better than approximately below the 2nd percentile of the general population on standardized intelligence measures. May indicate need for support.

What an IQ of 70 Means

IQ scores are standardized with a mean of 100 and a standard deviation of 15. A score of 70 is 2.0 standard deviations below the mean. The classification "Extremely Low" is used by psychologists to describe this range of cognitive ability.

It's important to remember that IQ scores measure a specific set of cognitive abilities under specific testing conditions. They provide a useful snapshot of certain aspects of intelligence but don't capture the full picture of a person's capabilities, potential, or worth.

Factors That Influence Your Score

Your IQ score reflects a combination of genetic potential and environmental influences including education, nutrition, health, and the testing conditions themselves. Factors like fatigue, anxiety, unfamiliarity with the test format, and even the time of day can all affect performance. A single test score should be viewed as an estimate, and scores can vary by several points between testing sessions.

What Can You Do With This Information?

Rather than focusing on the overall number, look at your domain-specific scores if your test provides them. Most comprehensive assessments break down performance across areas like verbal reasoning, spatial ability, working memory, and processing speed. Understanding your cognitive profile, your relative strengths and areas for growth, is far more actionable than the single composite score.
