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.
