IQ 102 interpretation
Most people score near this range because many IQ tests are normed around an average score of 100.
The percentile means that this score is higher than roughly 55.3% of the norm group and lower than roughly 44.7% of the same group.
A single IQ number should be interpreted together with the specific test, age norms, confidence interval, and the pattern of strengths and weaknesses across subtests.

IQ score meaning FAQ
One IQ number is only a summary. It should be read with the test name, score range, confidence interval, age norms, and subtest pattern.
Tests can differ in tasks, timing, norms, reliability, language, and difficulty. Motivation, fatigue, and test conditions can also affect results.
A higher score can indicate stronger performance on certain cognitive tasks, but real-life success also depends on knowledge, habits, health, personality, opportunity, and goals.
Practice can improve familiarity with task types and reduce test anxiety. That does not always mean the underlying ability changed by the same amount.
Read the full score chart, percentile guide, and age-norm explanation. Together they give a more balanced view than a single score page.
