What would 151 be on other tests?

Not every test would print 151 for this position. Older Stanford-Binet forms and many school tests use a standard deviation of 16; there, the same position as 151 is about 154. On a scale with a standard deviation of 24, used by the Cattell test, it is about 182. 151, 154 and 182 all mean the same percentile.

Is 151 a good IQ score?

The scale does not grade the person behind a 151; it places one result among other people’s results. As a position, 151 is far above the average of 100. What a 151 is useful for depends on the purpose, and a single online result is too rough for decisions about school, work or support. A 151 describes some kinds of reasoning on one test, on one day, and leaves out a great deal that matters, such as effort, knowledge and character.

Only if the 151 comes from a supervised test that Mensa accepts. American Mensa accepts scores at or above the 98th percentile, and 151 is at the 99.97th percentile.

Is 151 a genius IQ?

No test or psychology dictionary calls 151 a genius score, or defines one at all. The often quoted 140 goes back to a long-term study that selected children scoring above 140; by that line, 151 is 11 points over it. What a person with a 151 achieves depends on far more than a test number, as what IQ is considered genius explains.

Can any test measure a score of 151?

Every test has a ceiling, a highest score it can give, and few tests are built to measure as high as 151. The WISC-V full-scale score, for example, runs from 40 to 160, so 151 sits near its top. On our own test the range gets wider on the way toward 151: about 24 points wide at 100 and about 28 points wide at 140. Our page on the highest IQ score explains why scores like 151 are hard to pin down.
