IQ Score Interpretation Guide
IQ scores are usually standardized so that the average performance of a reference group is assigned to a defined score range. Understanding what those ranges mean helps prevent overinterpreting a single number.
Average range
Most IQ scales place the average score near 100. Scores within a moderate band around that value are common and should be seen as typical rather than exceptional.
Above-average and high scores
Scores that are notably above average may suggest strong performance in reasoning and problem-solving tasks, though they do not guarantee success in all domains or contexts.
Below-average scores
Lower scores can reflect difficulties with specific cognitive tasks or may simply be the result of test conditions, fatigue, or unfamiliar question formats. Interpretation should be cautious and contextual.
Percentiles and context
Percentile ranks are often easier to understand than raw scores because they show how a result compares with others in the same age group. Even then, a percentile is only one piece of information and should not be treated as a complete profile.
