Understanding the percentile
An approximate 91st percentile means measured performance was as high as or higher than that of about 91% of the relevant norm group. It does not mean 91% of items were correct.
The exact percentile varies slightly by test, age band, and norm table. The report’s own conversion table should take priority.
Likely interpretation
A score of 120 is commonly described as above average or high average. It may reflect strong performance in the reasoning, learning, or problem-solving skills sampled.
The overall score can conceal uneven abilities. Verbal, visual, memory, and speed indexes offer a fuller picture in a comprehensive battery.
What the score cannot guarantee
An IQ of 120 does not guarantee academic success, career performance, creativity, emotional maturity, or good decisions. Opportunity, effort, health, interests, and personality remain important.
Because every score has a margin of error, 120 is better viewed as a range around an estimate than an exact lifelong value.
