Same percentile on every row; the number changes because the scales use different standard deviations.

How rare is an IQ of 135?

IQ 135 is higher than 99.02 percent of scores. About 1 in 102 scores are at or above this point in the distribution.

That position places 135 near the top of the range described as Extremely High. The percentile describes how a score compares with scores in the distribution; it does not predict performance on a particular task.

Why is one test less precise at 135?

One test gives a less precise result far from the mean. A score at this distance should be read as an estimate from that test, rather than a perfectly exact measure of a person's reasoning ability.

A single result does not show how consistent the person's performance would be on another test or task. IQClock offers a timed reasoning test, but it does not print an IQ score or percentile.

What is 135 on SD 16 and SD 24 scales?

The same position as 135 is 137 on an SD 16 scale and 156 on an SD 24 scale. Those values refer to equivalent positions, not identical score numbers.

The difference matters when someone compares results reported by different tests. The score number alone does not establish that two results use the same scale, so the scale needs to be known before comparing them.

Questions

Is IQ 135 considered extremely high?

Yes. IQ 135 falls in the Extremely High band, which covers scores of 130 and above. The band is a label for a score range; it does not describe every aspect of a person's skills or predict what they will do.

What percentage of scores are 135 or higher?

About 0.98 percent of scores are at or above 135. This is the share represented by the score distribution, while 1 in 102 expresses the same rarity as a ratio.

Does IQ 135 qualify for Mensa?

Mensa's own page gives a Cattell-scale qualifying score of 148. Since 135 and 148 are reported on different scales, those numbers alone cannot establish whether a result qualifies. Check the test and scale shown on the score report.
