Is 112 a Good IQ Score? What It Actually Means

Haven't tested yet, or not sure your last result was reliable? You can take our 50-question assessment and get your score with a full percentile breakdown across four cognitive domains.

What does an IQ of 112 actually mean?

IQ scores are standardised so that the population average is 100 and the standard deviation is 15. A score of 112 is 12 points above the mean — about 0.8 standard deviations. In plain language: you're clearly above average, but you're not far enough above average to be called “high IQ” in the technical sense.

The Wechsler Adult Intelligence Scale (WAIS-IV, and the newer WAIS-V published in 2024) classifies scores from 110 to 119 as High Average. Scores above that move into Superior (120-129) and then Very Superior / Gifted (130+). So 112 is in the first band above the everyday average range — ahead of roughly four out of five people you meet, but not an outlier.

The exact percentile for an IQ of 112

Using the standard normal distribution with a mean of 100 and standard deviation of 15, an IQ of 112 maps to the 78.81st percentile — usually rounded to 79. The table below shows how 112 sits relative to neighbouring scores:

So if you put 100 people in a room, about 21 of them would score higher than 112 and about 79 would score lower. In a typical office of 50 people, you'd expect around 10-11 to have a higher IQ than you.

How much to trust a single score of 112

Even the best clinical IQ tests have measurement error. The WAIS-IV has a test-retest reliability of about 0.96 for the Full Scale IQ, which is excellent — but not perfect. The standard error of measurement is typically ±3 to ±5 points (Gigacalculator / Wikipedia cite ±3; other sources use a wider band).

In practical terms, if you scored 112, your “true” latent IQ most likely sits between 107 and 117. You might also retest on a different day, after better sleep, and come out at 115. Or you might retest stressed and sleep-deprived and land at 109. The number isn't a fingerprint — it's an estimate with a confidence interval around it.

This matters for how you interpret the result. A score of 112 should be read as “you're somewhere in High Average territory,” not as a precise ranking against someone who scored 111 or 113.

IQ 112 and education

This is where IQ 112 becomes particularly interesting. According to Kaufman et al.'s analysis of WAIS-IV normative data (2016), an IQ of 112 is approximately the average IQ of adults holding a master's degree. For comparison:

• High school graduates: mean IQ around 99
• Bachelor's degree holders: mean IQ around 110
• Master's degree holders: mean IQ around 112
• Professional degrees (MD, JD): mean IQ around 114
• Doctoral degrees (PhD): mean IQ around 115

The difference between a master's and a PhD in this data is only about 3 IQ points — well within measurement error. What that tells you is that by the time you're comparing graduate degree holders, IQ is a poor predictor of which level you'll reach. Motivation, funding, career goals, and opportunity cost matter far more than any remaining cognitive differences at this level.

Two points worth knowing. These are averages — there are plenty of people with master's degrees scoring well above or below 112, and plenty of people scoring 112 without a master's. And the correlation between IQ and education is driven mostly by selection (people with higher cognitive ability tend to pursue more education), with a smaller causal effect of education itself on measured IQ — around 1-5 points per additional year of schooling (Ritchie and Tucker-Drob, 2018). So a 112 with no degree is just as real a 112 as one with a master's.

What careers are typical at IQ 112?

IQ 112 is compatible with virtually every professional career. The occupational research (notably Hauser 2002, and summaries in Gottfredson 1997) suggests that most skilled professional roles cluster around mean IQs of 110-120. At 112 specifically, you're near the group mean for:

• Registered nurses and allied health professionals
• Primary and secondary school teachers
• Accountants (non-specialist)
• Middle managers in most industries
• Journalists and content editors
• Skilled trades supervisors and site managers
• Insurance underwriters
• Civil servants at mid-grade levels

You're close to the group means for doctors (around 115), and within striking distance of engineers (around 120) and research scientists (125+) — but those means hide enormous variation, and they don't define who can succeed in those fields. There are excellent doctors with IQs of 110 and mediocre ones with IQs of 130. Domain knowledge, work ethic, emotional intelligence, and communication skills all contribute more to real-world performance than another 10 IQ points would. At 112, almost every professional path is genuinely open to you.

Can you join Mensa with an IQ of 112?

No — Mensa requires a score at the 98th percentile, which on the Wechsler scale corresponds to approximately IQ 132. An IQ of 112 is at the 79th percentile, so roughly 20 points short of the threshold.

That said, Mensa eligibility is a narrow goal. The society is essentially a social club with a cognitive entry ticket — membership correlates weakly (if at all) with career success, income, relationships, or life satisfaction. At 112 you're already in the top 21% of the population, which is more than enough for virtually every career path that doesn't require exceptional mathematical or research talent.

If Mensa-level scores are a goal, the honest answer is that adult IQ is fairly stable. Training effects from practice and education add a few points — usually in the 1-5 point range — rather than shifting you across a full standard deviation. The bigger payoff in adult life tends to come from developing deep domain expertise, which compounds over time in ways that general cognitive ability alone does not.

What to keep in mind about an IQ of 112

A few things worth knowing so you can read your score accurately — not to talk it down, but because understanding these makes the number more meaningful, not less.

• It's a strong foundation, not a guarantee. IQ correlates well with educational attainment and income, but the relationship is partial — around 0.5 for school grades, 0.3-0.4 for adult income. The rest comes down to conscientiousness, network, timing, and luck. At 112 you have genuinely good cognitive raw material; how far it takes you depends on what you do with it.
• It opens more doors than it closes. Surgeons, senior engineers, and researchers with IQs in the 110-115 range exist in substantial numbers. Crossing some arbitrary threshold isn't what gets people to the top of demanding fields; sustained effort in a specific domain does. 112 is well above the minimum for essentially any career you'd want to pursue.
• It's an estimate, not a fixed attribute. Your score will naturally vary a few points from test to test and day to day. Education can nudge it upward modestly. This isn't a flaw of the test — it's how any measurement of a complex trait works. Treat your 112 as “somewhere in High Average territory” rather than a precise ranking.
• It captures one kind of intelligence. IQ measures the general factor behind reasoning and problem-solving — a genuinely important and well-studied thing. But creativity, wisdom, social skill, emotional intelligence, and deep domain expertise all contribute to how people actually succeed. Your 112 tells you something real about your cognitive horsepower; it doesn't tell you about those other strengths, which could easily be higher still.

The bottom line on IQ 112

An IQ of 112 is a genuinely good score. You're in the top 21% of the population, in the High Average classification on the Wechsler scale, and at roughly the same cognitive level as the typical master's-degree holder. Most professional careers are well within reach. You're below the thresholds for Superior (120), Mensa (132), and the gifted range (130+), but those thresholds are fairly arbitrary and tell you relatively little about how your life will go.

If you scored 112 on a reliable test, the practical read is: your cognition is working well for you, and you have the raw material for virtually any career path you want to pursue. The biggest gains from here come from developing deep skills in a field you care about — that's what compounds over a career, not moving a few points on an IQ scale.

And if you haven't taken a reliable test yet — or you took one of the three-minute Facebook quizzes and want a real number — that's where our assessment comes in.
