Short answer: An IQ of 134 is very superior: higher than about 98.8 percent of people, roughly 1 in 85. It qualifies for Mensa, whose Wechsler cutoff is 130. The top 1 percent begins at about 134.9 on the standard scale (mean 100, SD 15), so a 134 sits a fraction of a point below it, well inside the error of any single test.
Shaded: the share of people who score higher on a mean-100, SD-15 scale.

What 134 means on the standard scale
An IQ of 134 is 2.27 standard deviations above the mean. It ranks at the 98.83rd percentile, with 1.17 percent of people scoring higher. In a lecture hall of 300 students, three or four would reach that level.
The labels agree that this is elite territory. The WAIS-IV calls 130 and above Very Superior, the WAIS-5 calls it Extremely High, and the Stanford-Binet 5 places 130 to 139 in its Gifted or very advanced band. Our guide to IQ classifications compares every band.
The 99th-percentile line
On a scale with a standard deviation of 15, the exact 99th percentile falls at 134.9. That is why 135 is the conventional top-1-percent score and why 134 is the last whole number outside it.
| IQ | Percentile | Scoring higher | Rarity |
|---|---|---|---|
| 132 | 98.4 | 1.6% | 1 in 61 |
| 133 | 98.6 | 1.4% | 1 in 72 |
| 134 | 98.8 | 1.2% | 1 in 85 |
| 135 | 99.0 | 1.0% | 1 in 102 |
| 136 | 99.2 | 0.8% | 1 in 122 |

A gap smaller than any test can resolve
The distance between 134 and the 99th percentile is under one point. The error band on a single IQ score is about five points in each direction, so a measured 134 is consistent with a true score anywhere from about 129 to 139. Whether a particular 134 belongs to the top 1 percent is a question the test itself cannot answer.
For Mensa, the question is simpler. The society admits people at or above the 98th percentile on an approved, properly supervised test, and its Wechsler cutoff is 130. A 134 clears it by four points. The process is covered in how to join Mensa.
134 on other scales
Tests built on different standard deviations report the same standing with different numbers. On the older Stanford-Binet scale with an SD of 16, a 134 translates to about 136. On the Cattell scale, with an SD of 24, it becomes about 154, comfortably above Mensa's Cattell requirement of 148. None of these conversions changes the percentile. They only change the digits on the report.
Do small differences at the top matter?
Research on the gifted says they can, on average. The Study of Mathematically Precocious Youth, run from Vanderbilt University, has tracked more than 5,000 people first identified around age 13 through the SAT. In a 2008 paper in Psychological Science, Gregory Park, David Lubinski and Camilla Benbow followed 1,586 adolescents from the top 1 percent for more than 25 years. Within each degree level, from bachelor's to doctorate, the share holding a patent or a scientific publication rose with their age-13 SAT math score.
Two caveats. The measure was an SAT math score, not a full-scale IQ, and the pattern describes groups, not individuals. Lubinski and Benbow also stress that educational opportunity strongly shapes how talent develops. Is 134 a good IQ? Yes, and the evidence suggests even gradations this high carry signal. They do not carry certainty.
Getting a trustworthy number
A 134 worth citing comes from a standardized test, such as the WAIS-IV, WAIS-5 or Stanford-Binet 5, administered in person by a licensed psychologist. Online scores cannot be used for Mensa. Our free IQ test works as a practice screener only. For the reasons, read are online IQ tests accurate?

Frequently asked questions
Is an IQ of 134 in the top 1 percent?
Not quite. On a scale with a mean of 100 and a standard deviation of 15, the top 1 percent starts at about 134.9, so 134 sits at the 98.83rd percentile. The gap is far smaller than the roughly five-point error band of any single test, so a measured 134 may reflect a true score on either side of the line.
What percentile is an IQ of 134?
An IQ of 134 corresponds to the 98.83rd percentile on the standard scale. About 1.17 percent of people score higher, or roughly 1 person in 85. On an SD 16 scale the same rank reads as about 136, and on the SD 24 Cattell scale as about 154.
Does an IQ of 134 qualify for Mensa?
Yes. Mensa admits people at or above the 98th percentile, which is 130 on Wechsler-type tests. A 134 clears that by four points. The score must come from an approved intelligence test that was properly administered and supervised; online tests are not accepted.
Is 134 considered gifted?
On the Stanford-Binet 5, yes: scores from 130 to 139 carry the label Gifted or very advanced. The WAIS-IV calls the same range Very Superior. School gifted programs set their own criteria and frequently weigh other evidence, such as achievement and teacher ratings, alongside a test score.
