How rare is an IQ of 136?
An IQ of 136 is at the Very high level (Top ~2% (gifted level)). IQ follows a normal distribution with a mean of 100 and a standard deviation of 15, and an IQ of 136 sits as follows.

Measurement error: the realistic range of an IQ of 136
IQ scores always carry measurement error: the same person can score a few points higher or lower on a different day. A result of 136 is therefore best read not as an exact value but as somewhere around IQ 131–141 (±5). Under the normal-distribution model (mean 100, SD 15), that range corresponds to roughly the top 1.94% to the top 0.31% of the population.
Does 5 points matter? IQ 131 / 136 / 141 compared
| IQ | Top % | Rarity |
|---|---|---|
| IQ131 | 1.94% | 1 in 52 |
| IQ136this page | 0.82% | 1 in 122 |
| IQ141 | 0.31% | 1 in 319 |
A 5-point gap is within the typical measurement error of an IQ test: two people 5 points apart could easily swap places on a retest. Small differences between nearby scores should not be over-interpreted.
Characteristics and tendencies of an IQ of 136
The following are general tendencies seen at this level; individual differences apply. IQ measures one aspect of thinking, such as fluid reasoning.
- •Around the top 2%. A tendency toward finding complex patterns, abstract reasoning, and a high learning speed.
- •This falls within Mensa's admission range (the top 2%).
- •Strengths vary from person to person; a high IQ does not mean strength in every ability.
Relationship to Mensa
Mensa's admission criterion is "the top 2% (roughly IQ 130 or above)." An IQ of 136 may meet this criterion. Actual membership requires taking an approved supervised test.

- What percentile is an IQ of 136?

- It is at the Very high level (Top ~2% (gifted level)), placing it in roughly the top 0.82%. That said, IQ measures only a small part of thinking and does not determine a person's worth or success.
- Can you join Mensa with an IQ of 136?
- Mensa's admission criterion is "the top 2% (roughly IQ 130 or above)." An IQ of 136 may meet this criterion (actual membership requires taking an approved certification test).
- What is the deviation score for an IQ of 136?
- Converting IQ (mean 100, SD 15) to a deviation score gives about 74.
Common questions in the IQ 130–144 band
- Can I join Mensa with an IQ of 136?
- Mensa's criterion is the top 2%, roughly IQ 130 and above, so an IQ of 136 is at or above the line. Note that an informal online estimate does not count for admission — you would need to pass an accredited supervised test or submit approved prior evidence.
- Does an IQ of 136 mean I am gifted?
- An IQ of 136 falls in the range (130+) that many frameworks use as the gifted threshold — about 1 in 122 people. Formal identification, however, usually looks at more than one test score, and giftedness describes a pattern of abilities, not a guarantee of achievement.
- How rare is an IQ of 136 really?
- Under the standard model (mean 100, SD 15), an IQ of 136 is in roughly the top 0.82% — about 1 in 122 people. In a group of 1,000 people you would expect only about 8 at this level or higher.
Age and testing conditions
- •IQ is a deviation score relative to people of the same age: a score compares you with your own age group, so children's and adults' scores are not on the same footing.
- •Results from informal online tests, including the test on this site, are estimates. For medical or educational decisions, use a standardized test administered by a qualified professional.
- •Sleep deprivation, fatigue, and practice effects all move measured scores. Read any single result, high or low, with that in mind.
