Is 145 IQ Good? How Rare a 145 Score Really Is

6 min read · IQ Tester

Is 145 IQ good? Yes, it's a very high score. On a standard scale (average 100, SD 15), 145 is three standard deviations above average, about the 99.87th percentile, or roughly 1 in 740 people. The catch: that only holds on an SD-15 test, and a 145 from a quick online quiz is often less rare than it looks.

If you just got a 145 and want to know what's really behind it, which skills are elite and which one is secretly your weak spot, IQ Tester breaks your reasoning down by category: Find my weak spots.

Is 145 IQ good? Short answer

• Is 145 iq high? Yes. Is 145 iq very high? Also yes. Most test manuals put it in the "very superior" or "extremely high" band.
• Is 145 iq good or bad? Good. Just be ready for people to side-eye the number if it came from a random website.
• Is 145 high iq score for a teen? Yes, it means the same rarity at 13 as at 30 (explained below).
• Is 145 iq genius? Some older sources used "genius" for scores around 140+, but it's not a clinical label today. Is 150 IQ genius goes deep on that word.

How rare is 145? The maths

IQ scores follow a bell curve. The standard deviation (SD) is how far a "typical" step from the middle is. On most modern tests, 1 SD = 15 points.

• 115 = 1 SD above average
• 130 = 2 SD above average
• 145 = 3 SD above average

Here's how fast rarity climbs up there:

What does 1 in 740 look like in real life?

• A big high school of 1,500 students: maybe 2 people.
• A whole university of 20,000: around 27.
• A stadium of 60,000 fans: about 80.

Rare, but not mythical. For comparison, is 135 IQ good shows the more common top-1% zone.

Why 145 on one test isn't 145 on another

This is the most important section if you're trying to figure out if your score is legit.

Different tests, different SDs

Not every test uses SD 15:

See the problem? A 145 on an SD-24 test is roughly a 128 on the usual scale. Still great, but way less rare. Always check the SD before you screenshot it for the group chat.

Online norms

A lot of online tests compare you to their own visitors, not a carefully balanced sample. Some also inflate scores because a high number gets shared more. Classic engagement move.

Ceiling effects

Many tests aren't built to measure accurately up at 145. If a test only has a handful of truly hard questions, getting a couple extra right can swing your result a lot. IQ Tester's own reported scale runs from 58 to 142, which is honest about where it can measure.

Is 145 'genius'?

Not officially. Early 20th-century psychologists like Lewis Terman used words like "genius or near genius" for very high scores, but modern tests use labels like "very superior" or "extremely high." Today, "genius" is usually saved for people who actually created something groundbreaking, which no test score guarantees.

Is 145 iq good for a 13, 14, 15 or 16 year old?

Yes. Proper IQ tests are age-normed, so a 145 at 14 means you did about as well as the top 1 in 740 14-year-olds. Teen scores can move a fair bit between tests, though, so treat it as "very strong right now," not a lifetime label.

Life with a very high score

A 145 doesn't come with a manual. A few honest things people in that range often run into:

• Boredom in class. When you get it the first time, the third explanation hurts. Ask for harder work instead of zoning out.
• Never learning to struggle. If school was easy until now, the first genuinely hard course (AP, A levels, IB, first-year uni) can feel like a shock. Practice being bad at things on purpose.
• Overthinking. Seeing ten angles on every problem is great, until you can't pick one. Deadlines help.
• Imposter feelings. Weirdly common. A number doesn't cancel out normal human doubt.
• Social stuff. Nobody in your group chat wants the IQ talk. Connect over shared interests, not scores.

Here's the tricky bit: even at 145, you can't tell from one number which skill carried you and which one's lagging. It's genuinely hard to spot your own blind spots. IQ Tester makes hard questions count for more, treats a skip as wrong, and breaks your answers into number series, verbal analogy, logic and pattern, so your weak spot has nowhere to hide.

Checking a high online result

Got a 145 online? Here's a quick sanity check:

1. Find the SD. If the site doesn't say, the number is hard to interpret.
2. Check the question count. A 10-question quiz can't reliably separate 130 from 145.
3. Was it timed? Timed tests reward speed; untimed ones reward accuracy. Different skills.
4. Did you skip anything? Some tests quietly ignore skips, which inflates scores.
5. Try a second, different test. If both land high, that's a stronger signal. If one says 145 and another says 118, trust neither as exact.
6. For anything official (school programs, Mensa), you'll need a supervised, approved test. Online scores don't count, including ours.

For scores above this, the 160 IQ percentile post covers why most tests can't even measure that high.

Test your 145 against harder questions

FAQ

What percentile is 145 IQ?

On a standard SD-15 scale, 145 is about the 99.87th percentile, or roughly 1 in 740 people. On an SD-24 scale, the same number is only around the 97th percentile.

Is 145 IQ very high?

Yes. It's three standard deviations above average on most modern tests, which puts it in the "very superior" or "extremely high" range.

Is 145 IQ good for a 16 year old?

Yes. Because real IQ tests compare you to your own age group, 145 at 16 is just as rare as 145 for an adult. Teen scores can still shift between tests, so take any single result with some caution.

Is 145 IQ genius level?

Some older writers called scores like 140+ "genius," but modern tests don't use that label. A 145 means very strong reasoning on the test; genius usually refers to what someone creates.

Are online 145 IQ scores accurate?

Often not exactly. Many online tests use unusual scales, small question sets or their own users as norms, which can inflate high scores. Check the standard deviation and compare with a second test.
