What does an IQ of 130 mean?

Short answer: An IQ of 130 is two standard deviations above the average of 100 on the standard IQ scale, where the standard deviation is 15. By the normal curve, that puts 130 at the 97.7th percentile: about 2.3% of people, roughly 1 in 44, score 130 or higher. The WAIS-IV calls 130 and above Very Superior. It is a high score, and none of the test tables we checked calls it "genius". Like any IQ score, it carries a range of a few points either way.

IQ 130 at a glance

These figures come from the normal curve unless a test is named. The APA task force report "Intelligence: Knowns and Unknowns" (1995) describes the scale: an average of 100, a standard deviation of 15, and about 95% of people between 70 and 130.

• Distance from average: 2.00 standard deviations above 100, since (130 − 100) ÷ 15 = 2 (our calculation).
• Percentile: 97.7th by the normal curve (our calculation).
• How rare: about 2.3% of people score 130 or higher, roughly 1 in 44 (our calculation).
• WAIS-IV label: Very Superior (130 and above).
• WISC-V label: Extremely High (130 and above).
• Stanford-Binet 5 label: Gifted or very advanced, as secondary sources reproduce its table.
• Woodcock-Johnson IV label: Superior (121 to 130). Very Superior starts at 131.
• Mensa: the American Mensa list names a Full Scale IQ of 130 as qualifying on the Wechsler tests, but other tests need 131, 132 or 148.
• Error range: on a test with reliability .97, a 95% range around 130 runs from about 125 to 135 (our calculation).

Is 130 a good IQ score?

Yes. A 130 is well above the average, which is set at 100 by definition. Only a small share of people reach it on a well-normed test.

"Good" is a loose word for a measurement, though. An IQ score is a position on a scale compared with a norm group of people your age. It says how you did on that test, on that day, against those people. It is not a grade on you as a person. Our guide to the average IQ explains how the scale is built.

What percentile is 130, and how rare is it?

The percentile comes straight from the normal curve. The NIST/SEMATECH e-Handbook of Statistical Methods, from the US National Institute of Standards and Technology, gives 95.45% of a normal population within two standard deviations of the mean. The rest sit outside, split evenly between the two tails, so 2.275% sit above +2 SD.

On the IQ scale, +2 SD is 130. The calculation:

1. Find the z-score. (130 − 100) ÷ 15 = 2.00.
2. Look it up on the normal curve. The curve puts 97.7% of people below z = 2.00, so 130 is the 97.7th percentile.
3. Turn the share into "1 in N". 1 ÷ 0.02275 is about 44, so roughly 1 person in 44 scores 130 or higher.

You will see "1 in 50" on some pages. That figure belongs to the 98th percentile, which on this scale is about 130.8. A 130 sits just below it. The neighbors show how fast the numbers thin out at the top: by the same curve, 125 is the 95.2nd percentile and 135 is the 99.0th.

These are values from an ideal curve. Real tests publish their own norm tables, which can differ a little at the ends. Our guide to IQ percentiles has the full score-to-percentile list, and the IQ bell curve shows how scores spread.

What 130 is called on each test

Each test publisher prints a word next to each score band. The words differ, and so do the band edges.

• WAIS-IV (adults): a 2019 study in Psychiatry Investigation grouped WAIS-IV full-scale IQ by the descriptive classification of intelligence by Wechsler, with Very superior for 130 and above and Superior for 120 to 129 (Hwang and colleagues). A 2020 case report in BMC Psychiatry prints the same two bands for the WAIS-IV Processing Speed Index (Hemmingsen and colleagues).
• WISC-V (children): a 2024 study protocol by Medise and colleagues in Frontiers in Pediatrics classifies WISC-V scores of 120 to 129 as very high and 130 and above as extremely high. A 2022 study by Holeva and colleagues in the Journal of Autism and Developmental Disorders uses the same very high band and calls a score above 130 extremely high.
• Stanford-Binet Fifth Edition: the IQ classification article on Wikipedia reproduces its table with 130 in the band "Gifted or very advanced". We found no publisher page to confirm it.
• Woodcock-Johnson IV: its publisher, Riverside Insights, puts 121 to 130 in Superior and 131 and above in Very Superior. So on the WJ IV, 130 is the top of Superior, one point short of the next label.

Pearson, which publishes the Wechsler tests, says on its WAIS-5 and WISC-V pages: "Qualitative descriptors are only suggestions and are not evidence-based; alternate terms may be used as appropriate." The label is a way to describe the number in words. The number and its range are what a report actually measures.

Is an IQ of 130 gifted?

It depends on who is asking, and the answer comes from a school's rules as well as the score. In the US, gifted programs are run by states and school districts, and each sets its own rules.

Two state rules show how 130 is used:

• Florida: its rule 6A-6.03019 lists, among its criteria, "an intelligence quotient of two (2) standard deviations or more above the mean on an individually administered standardized test of intelligence." On a test with a standard deviation of 15, that is 130. The same rule also asks for a need for the program and a majority of gifted characteristics on a checklist, and it allows a second route for students from under-represented groups, meaning students with limited English proficiency or from a low socio-economic status family, through an approved school district plan.
• Pennsylvania: title 22, section 16.21 of the Pennsylvania Code says the term "mentally gifted" includes "a person who has an IQ of 130 or higher or when multiple criteria as set forth in this chapter and in Department Guidelines indicate gifted ability." It adds: "Determination of gifted ability will not be based on IQ score alone." A student with a score below 130 may still be admitted when other criteria strongly indicate gifted ability.

The National Association for Gifted Children, or NAGC, says: "Typically, identification policies and procedures are determined at the district level." It also says: "One test at a specific point in time should not dictate whether someone is identified as gifted." NAGC adds that many consider children in the top 10% on a national or local norm a good guide for identification and services. By the normal curve, the top 10% starts near 119, well below 130 (our calculation).

So a 130 meets a common cutoff, but no score decides on its own whether a person is gifted. If the question is about a child's school placement, the school psychologist and the district's own rules give the answer.

Does a 130 get you into Mensa?

Often, but not on every test, and never on an online one.

Mensa International states that "the only relevant qualification for membership is scoring within the upper 2% of the general population on an approved intelligence test." On an ideal curve with a standard deviation of 15, the top 2% starts at 130.8 (our calculation). American Mensa's list of qualifying scores still names 130 for several tests:

• Wechsler adult and children's scales: Full Scale IQ 130, for the WAIS through the WAIS-IV and the WISC through the WISC-V.
• Stanford-Binet 5: 130. Reynolds Intellectual Assessment Scales: 130.
• Woodcock-Johnson IV: 131. Editions I to III: 132.
• Older Stanford-Binet editions: 132. Cattell: 148.

These numbers do not all mark the same position. The older Stanford-Binet and Cattell cutoffs sit two standard deviations above average on scales with wider spreads. On a scale with a standard deviation of 16, two standard deviations above average is 132, and on a scale with a standard deviation of 24 it is 148 (our calculation). The Woodcock-Johnson cutoffs are a different case. Riverside Insights, which publishes the WJ IV, puts 121 to 130 at percentile ranks 92 to 97 and 131 and above at percentile ranks 98 to 99.9. So on the WJ IV, the 131 Mensa asks for is a slightly higher position than a Wechsler 130. We found no publisher table for editions I to III, so we cannot say where their 132 sits.

The spread matters in the other direction too. A 130 on a scale with a standard deviation of 24 is only about the 89.4th percentile (our calculation). Always check which test and scale a score was reported on.

American Mensa adds three rules that matter for a 130:

1. The whole test. "The Wechsler tests must be given in their entirety," and Mensa requires a Full Scale IQ. For the WISC-IV, WISC-V and WAIS-IV, it accepts the General Ability Index instead when two index scores differ by 1.5 standard deviations or more.
2. Supervised testing only. "We do not accept unsupervised testing as proof of eligibility, specifically unsupervised testing administered electronically, or via internet-based tests." For a test given by an institution, agency or clinic, the report must be signed by "the psychologist responsible for the testing."
3. The WAIS-5 is not on the list we read on 26 October 2026. If your score comes from it, ask American Mensa before you rely on it.

Is 130 a genius IQ?

No. "Genius" is not a label on the test tables we checked: the WAIS-IV, WISC-V, Stanford-Binet 5 and Woodcock-Johnson IV.

The genius label on an IQ table comes from Lewis Terman's book The Measurement of Intelligence (1916). His table put a row labeled near genius or genius above 140, and 120 to 140 was "Very superior intelligence." So even on Terman's table, 130 was not in the genius row. His scores were also a different kind of number. In the same book, Terman defines the intelligence quotient as "the ratio of mental age to chronological age." Modern scores rank you within your age group on the normal curve instead.

Terman himself warned that "the boundary lines between such groups are absolutely arbitrary, a matter of definition only." That is still true. The line at 130 is a convention.

Why your 130 is a range

Every test has measurement error. In Hall v. Florida (2014), the US Supreme Court wrote that experts "have agreed, for years now, that IQ test scores should be read not as a single fixed number but as a range." It quoted the APA's brief: "1 SEM equates to a confidence of 68% that the measured score falls within a given score range, while 2 SEM provides a 95% confidence level."

SEM stands for standard error of measurement. Assessment Systems Corporation gives the classical formula as SEM = SD × √(1 − r), where r is the test's reliability. Winter, Trudel and Kaufman report in the Journal of Intelligence (2024) that the Full Scale IQ on the WAIS-5 has a mean reliability of 0.97. Put those together:

• SEM: 15 × √(1 − 0.97), which is about 2.6 points (our calculation).
• 95% range around a 130: 130 ± 1.96 × 2.6, about 125 to 135 (our calculation).
• 90% range: about 126 to 134 (our calculation).

That 95% range spans the 95.2nd to the 99.0th percentile. Pearson's WAIS-IV page adds that reliability is lower for gifted samples, because "the restriction in the range of scores obtained by these groups frequently results in lower reliabilities." So the range around a high score may be a little wider than the whole-sample figure.

Sam, who is invented for this example, gets a 130 on one test and a 126 on another a year later. That is not evidence that Sam got less intelligent. Both scores sit inside the range either test would expect.

Will a 130 come out the same on a retest?

Not exactly, and the direction is predictable in a few ways.

• Practice raises scores. Winter, Trudel and Kaufman report mean Full Scale IQ gains on a retest of about 4 to 6 points on the WAIS-III, 4.5 to 5 on the WAIS-IV and 3.7 on the WAIS-5 for ages 16 to 69. Our guide on whether you can study for an IQ test covers this in detail.
• Old norms read high. The APA task force report gives an average gain of "about three IQ points per decade." Winter and colleagues found a smaller rise of 1.2 points per decade between the WAIS-IV and WAIS-5 norms. Either way, a test normed long ago tends to give a higher number. Our article on the Flynn effect explains why.
• High scores drift back. Pearson notes that "some examinees exhibit scores that regress to the mean upon retesting." So a high score on one sitting can come back a little lower on the next.
• Different tests weigh different skills. Pearson's WAIS-IV page notes that "Gifted examinees tend to score lower on Processing Speed subtests relative to subtests from other scales." Two people with a Full Scale 130 can have very different index scores underneath.

What a 130 tells you, and what it does not

A 130 tells you that you did better than most of the norm group on the abilities that test samples. The APA task force report found that IQ tests "do in fact predict school performance fairly well", with a correlation with grades of about .50, which accounts for about 25% of the variance. For jobs, tests "predict considerably less than half the variance of job-related measures."

The same report says "intelligence tests measure only some of the many personal characteristics that are relevant to life in contemporary America."

A 130 does not tell you your future job, your income or your worth. It does not diagnose anything, and it does not rule anything out. If a score is part of a question about learning, attention or school placement, a licensed psychologist is the right person to interpret it.

An online 130 and a clinical 130

A clinical IQ test is given one to one by a trained examiner. The APA says a psychological assessment can include "norm-referenced psychological tests, informal tests and surveys, interview information, school or medical records, medical evaluation, and observational data", and that "not just anyone can perform a psychological evaluation." A clinical 130 comes from that setting, on a test with published norms and a known error range.

An online 130 is a different thing. It can be a useful estimate, but it is not a clinical result: American Mensa does not accept it, and the main route in Florida's gifted rule asks for an individually administered test. Our guide on whether IQ tests are accurate explains what separates a careful online test from a careless one.

If you want an estimate of where you stand, the WhatIQ test has 24 picture puzzles and takes about 15 minutes. It gives a score on the standard IQ scale with the range it most likely sits in, and it calls the result "an estimate from 24 puzzles, not a clinical assessment" (whatiq.com, read 26 October 2026).

Frequently asked questions

How rare is an IQ of 130?

By the normal curve with an average of 100 and a standard deviation of 15, about 2.3% of people score 130 or higher. That is roughly 1 in 44. The "1 in 50" you may see elsewhere is the share above the 98th percentile, which is about 130.8 on this scale.

What percentile is an IQ of 130?

The 97.7th percentile on a scale with a standard deviation of 15, because 130 is exactly two standard deviations above the average. On a scale with a standard deviation of 24, the same 130 is only about the 89.4th percentile. Check the scale before you compare two scores.

Is 130 IQ enough for Mensa?

On some tests. American Mensa lists a Full Scale IQ of 130 as qualifying on the Wechsler scales and the Stanford-Binet 5, but 131 on the Woodcock-Johnson IV and 148 on the Cattell. The test must be supervised. American Mensa does not accept unsupervised or internet-based tests.

Is 130 IQ gifted?

It meets a common school cutoff, but schools decide. Pennsylvania names an IQ of 130 or higher among its criteria and says the decision is not based on IQ alone. NAGC says districts set their own procedures and that one test should not decide on its own.

Is 130 a genius IQ?

No. None of the test tables we checked uses the word genius. Lewis Terman's 1916 table put a row labeled near genius or genius above 140 and 130 inside "Very superior intelligence", and his scores were ratio IQs, a different kind of number from today's.

Can a 130 change if you retake the test?

Yes. Practice can add a few points on a retest, old norms tend to read high, and high scores tend to come back a little closer to the average. On a test with reliability .97, the 95% range around 130 runs from about 125 to 135, by our calculation.
