Is 125 a good IQ?

125 is 25 points above average and 1.67 standard deviations up. You score higher than 95.2% of people, so in a class of 30 you would typically be one of the top 1. It sits 10 points into the above-average band, 5 short of the 130 mark often used for gifted programmes.

The gap between you and the average person is real but modest. On any single task, effort, experience and knowledge can easily outweigh it.

Most people at 125 were never labelled gifted at school, and many never took a formal test. It is the kind of score people underrate because it does not come with a label.

Careers are chosen, not assigned by score. Research on general mental ability, summarised in work such as Schmidt and Hunter (1998), suggests a 125 helps most in complex roles and during training.

Fields that reward this profile include engineering, analysis, teaching, nursing, law, finance, software and skilled technical trades, where learning new material is part of the job.

Where you end up depends heavily on interest, persistence and people skills. None of those is measured by an IQ test.

Here is how a 125 tends to show up outside a test, bearing in mind that plenty of people at this level notice none of it:

• You tend to spot the pattern in a problem sooner, especially with numbers, diagrams or rules.
• New tools and apps feel intuitive faster, because you infer how they work.
• Skills such as writing, coding or playing an instrument still take years of practice to master.

Scoring 125 or higher is a 4.8% share of everyone. Scaled up to whole populations, that works out as:

Going from 120 to 125 makes a score 1.9 times rarer, and going on to 130 multiplies the rarity by another 2.1. Near 125, each single point adds about 15% to the rarity.

What your 125 could really be. If you retook a well-made test, landing at 120 or at 130 would be unremarkable. That is the difference between beating 90.9% and 97.7% of people, and short online tests are noisier still.

Which scale was it on? A 125 reported on an SD 16 scale converts to about 123 on the usual SD 15 scale, and one from an SD 24 scale (seen in some Cattell-style results) to about 116. Check which scale your score report used.

Retrospective estimates for historical figures rarely go this low, because they are only made for people with exceptional achievements. A few sit near 125. Treat these as informed guesses from biographies rather than results. Each profile sets out what its estimate rests on.

Our degree, university and job profiles carry rough IQ benchmarks. These are the ones within a few points of 125. The education figures are derived from admissions-test averages, not from IQ testing.

125 is about 1.67 standard deviations above the mean, roughly 1 in 21 people. It is clearly above the vast majority, with a visible tier above it.

People at 125 are often told they are clever throughout life without ever getting a label. The gap to 130 is the gap between roughly the top 5% and the top 2%. Admissions tests and IQ tests overlap, but they are not the same measure.

Nearby scores and the round-number landmarks, so you can see how quickly the percentile changes around 125. Every row links to that score's page.

People with an IQ of 125 typically score about 1350 on the SAT and about 27 on the ACT composite. Scores vary a lot from person to person, so the range shows where about four in five land.
