Is 124 a Good IQ Score?

An IQ of 124 sits above roughly 95 in 100 people. The average is 100, and about two thirds of everyone scores between 85 and 115. You're clearly past that middle group. In the United States, around 18 million people score at this level or higher.

On the reasoning side, almost nothing is off the table. Research on jobs and complexity finds the most demanding professional work draws heavily from this level and up. But the same research shows big overlap: every profession is full of people scoring below this range.

Here's what the score doesn't settle. There's no magic line just above this group. The gap between 124 and the Mensa mark of 130 is 6. Yet research on gifted groups shows no proven cliff in real life on either side of that line. The score also says little about money: long-term studies find IQ explains only a small slice of income differences.

And it isn't a promise. Drive, judgment and follow-through are measured nowhere on the scale.

Research on people at this level finds that complex, abstract, unfamiliar material is where the difference shows. New systems, dense reading and layered problems tend to be picked up quickly, with less repetition than most people need. Long training pipelines — degrees, certifications, technical fields — tend to be completed at high rates.

What the research doesn't find is a distinct personality or a typical weakness that comes with the score. Studies of very able groups show ordinary human variety in everything else. And on familiar, well-practiced tasks, the advantage over average scorers mostly disappears.

Workplace studies add a caution: reasoning scores explain a modest slice of job performance, and traits like conscientiousness — steady follow-through — carry real extra weight. At this level, research suggests, outcomes hinge less on raw ability and more on where it gets pointed.

A 138 on a Cattell-scale test is the same result as 124 here. This is the most common reason two tests seem to disagree.

Mensa accepts 130 and above on this scale. 124 is 6 points short.

Scores in this group appear across the whole world of work, but published studies place several demanding professions' usual worker ranges over it:

• Engineers — layered technical problem-solving
• Attorneys — dense reading and argument
• Physicians — long training and constant judgment
• Research analysts — abstract work with data
• Advertising and other managers — strategy with moving parts
• College professors — building and teaching new knowledge

These ranges describe real workers, not entry bars, and every one of these fields includes people scoring below this group. The figures come from Hauser's Wisconsin study and Gottfredson's 1997 review.

Yes, clearly. Only about 5.5 percent of people score at this level or higher. The main adult test calls this range superior. Research links this level with fast learning of complex material and with demanding professional work. What it can't tell anyone is how the ability will be used.

About 1 in 18 people score 124 or above. In a room of 100, expect around 5 at this level or higher. Across the United States, roughly 18 million people are at or past it. Rare enough to stand out, common enough that you'll keep meeting your match.

Not quite — Mensa's line is 130 on this scale, and the gap from 124 is 6. But scores wobble by around five points, so a supervised sitting could land either side. Mensa accepts about 200 different supervised tests and never online ones. On the Stanford–Binet scale, where your result reads about 126, their line is 132.

Expect a retake to land between 119 and 129. That swing is measurement noise, not real change — sleep, focus and puzzle familiarity all nudge it. Quick online tests wobble more than supervised ones. If the exact number matters to you, a test given by a psychologist is the steady version.
