Question

Does Mensa tell you your IQ?

Short answer

Not in the United States. American Mensa says it does not give test takers a detailed report, a percentile rank or an IQ score; the result is whether you qualified, meaning you scored at or above the 98th percentile. If you want an actual IQ score, you need a full test from a qualified professional.

What you learn from a Mensa test

American Mensa defines a qualifying score as at or above 98 percent of the general population (American Mensa: testing), and says it does not give test takers a detailed report, a percentile rank or an IQ score (American Mensa: testing page). In practice the result is a yes or a no: you qualified for membership, or you did not.

One American Mensa local group describes the admission test as two separately timed, proctored tests, where a 98th percentile score on either one qualifies (South Texas Mensa: testing). A format like that is designed to find a cutoff, not to place you precisely.

Which tile comes next?

Tap the option you think is right, or show the answer.

Show the answer

The missing tile shows a very large outlined arrow pointing right (option 2).

How to solve it

  1. Compare neighboring tiles and name what changes each time.
  2. From tile to tile, the arrow turns a quarter turn clockwise.
  3. The fill cycles outline, solid and hatched, then starts again.
  4. Everything else stays the same from tile to tile.
  5. The last tile shows a very large hatched arrow pointing up. Apply each change once more.
  6. So the missing tile shows a very large outlined arrow pointing right.

That was 1 puzzle. The full test has 25.

If you want a number

  • A clinical assessment gives a Full Scale IQ and index scores. American Mensa accepts, among others, a Wechsler Full Scale IQ of 130 or 130 on the Stanford-Binet 5 (American Mensa: qualifying scores), so one well-run assessment can answer both questions. See what a Full Scale IQ is.
  • An online estimate gives you a rough number for curiosity. Ours reports an estimated IQ with a confidence range. It cannot be used for Mensa.

Reading a qualifying result

Qualifying tells you that you scored at or above the 98th percentile on that day, which is about 131 or higher on a standard deviation 15 scale. It does not tell you whether you are at 131 or 151. For how rare scores at the top are, see the top 2 percent and what IQ you need for Mensa. For the test format, see the Mensa admission test.

Questions

Why does Mensa not give an IQ score?

The admission test is built to answer one question, whether you reach the 98th percentile, not to measure your exact level. American Mensa states that it does not provide a detailed report, percentile or IQ score.

How do I get a precise IQ score?

A full clinical test, such as a Wechsler scale given by a qualified professional, reports a Full Scale IQ with index scores. American Mensa accepts a Wechsler Full Scale IQ of 130 as prior evidence.

Does IQ Octopus give a score?

Yes: an estimated IQ with a confidence range and percentile, for personal use. It is not a clinical score and cannot be used for Mensa.
