If you have always been near the top of the class, an IQ test raises a natural question: how far into the tail do I sit?

Here is how to read a high score honestly.

High IQ society thresholds

High IQ societies set entry at a percentile on approved, supervised tests. On a scale with a standard deviation of 15, those percentiles convert to the scores below. The rarity column is computed from the normal curve.

Society	Entry level	IQ equivalent (SD 15)	Rarity
Mensa	Top 2%	about 130	about 1 in 44
Intertel	Top 1%	about 135	about 1 in 102
Triple Nine Society	Top 0.1%	about 146	about 1 in 924
Prometheus Society	Top 0.003%	about 160	about 1 in 31,560

Why very high scores are less precise

Every test has a ceiling. With 25 questions, a couple of lucky or unlucky answers move a score a lot at the top end. Even clinical tests with many more items have wide confidence intervals in the 140s and above.

So if you score very high, read it as "very high" rather than as an exact number. And none of the societies above accept online results, ours included.

How this test works for high achievers

The five sets each run from easy to hard, so the last questions in each set carry the most information about high ability.

Accuracy beats speed, but the 12-minute clock is real.
Your first attempt is the honest one. Retakes inflate scores through familiarity.

What very high ability predicts

The Study of Mathematically Precocious Youth followed children who scored in the top 1 in 10,000 on reasoning tests at about 13. By their late 30s, as a group, they had earned doctorates, patents and senior academic posts at rates far above the general population, according to a 2013 follow-up by Harrison Kell, David Lubinski and Camilla Benbow.

The same research is clear that outcomes varied widely within the group. Very high ability raised the odds of exceptional achievement; it did not guarantee it.
