An IQ of 124 is in the superior range — higher than 95% of adults. This is a genuinely strong result.

What does IQ 124 mean in practice?

An IQ of 124 means your raw performance on a standardised IQ test places you at the 95th percentile of the general adult population — higher than 95% of people. People at this level typically find abstract reasoning, pattern-matching, and learning new skills comes naturally.

IQ 124 and the normal distribution

IQ is defined with a mean of 100 and a standard deviation of 15. An IQ of 124 is 1.6 standard deviations above the mean. The normal distribution tells us that:

• About 68% of people score between 85 and 115
• About 95% of people score between 70 and 130
• About 99.7% of people score between 55 and 145
• An IQ of 124 is higher than 95% of the adult population

IQ 124 and career outcomes

An IQ of 124 comfortably supports most knowledge-worker careers. Nurses, teachers, programmers, and managers typically average in the 110-120 range. At this level, habits, work ethic, and people skills account for far more of career success than the IQ number does.

How to accurately measure your IQ

A reliable IQ test uses Item Response Theory (IRT) scoring, which adapts the scoring based on item difficulty parameters rather than simply counting correct answers. Core Brain uses IRT 3PL (three-parameter logistic) scoring — the same statistical framework used by the WAIS and Stanford-Binet — and returns your score with a 95% confidence interval so you know the measurement uncertainty.
