Is 87 a Good IQ Score?

An IQ of 87 sits just under the average range, which is centered on 100. About two thirds of people score between 85 and 115. Depending on where 87 falls, it is inside or just below that big middle group. This is an ordinary score, and millions of adults in the United States share it.

Here's what it doesn't say. It isn't a disorder, a diagnosis, or a limit on what you can learn. It says nothing about effort, honesty, humor or skill at things you've practiced. The link between IQ and money is real but small: a large research review found IQ explains only a small slice of who earns what. Most of what decides income sits outside the score.

One test sitting is also a blurry snapshot. Sleep, nerves, reading speed and the test itself all push the number around. Quick online tests swing more than supervised ones. If a result ever matters for something real, a psychologist's full assessment is the version to trust — it looks at everyday skills too.

Five points of movement on a retake would be completely normal.

Research draws no sharp line between people here and people in the average range. The differences show up mainly when tasks get complex and unfamiliar. Learning that comes through practice and repetition usually goes fine. Hands-on work, routines and familiar problems are typically handled well.

What tends to take longer: dense written material, abstract puzzles seen for the first time, and switching between several new demands at once. Studies of work and daily life find that higher scores help most exactly there — in novel, complicated situations. On simple or well-practiced tasks, the gap between scorers largely disappears.

Researchers also stress how much people at the same score differ. Reading, training, health and support shape daily life at least as much as the number does.

A 79 on a Cattell-scale test is the same result as 87 here. This is the most common reason two tests seem to disagree.

Mensa accepts 130 and above on this scale. 87 is 43 points short.

Every job contains people with a wide spread of scores, so none of this is destiny. Published studies show these jobs' usual worker ranges cover this group:

• Machine operators and production workers — steady, practiced, hands-on work
• Welders — a skilled craft built by repetition
• Custodians — clear routines, little paperwork
• Food-service workers — fast but familiar tasks
• Cashiers — practical, structured customer work
• Nursing aides — care work learned on the job

People inside each of these jobs vary widely, and many score above average. The ranges come from Gottfredson's 1997 review and Hauser's Wisconsin study.

No. It's a bit below the average of 100, but it's an ordinary score that millions of people share. It doesn't mean anything is wrong, and it doesn't cap what you can learn with practice. It also says nothing about effort, character or common sense. One quick test decides even less.

About 19 percent score below this level, which works out to roughly 1 in 5 people at 87 or lower. Most people cluster near the middle: about two thirds score between 85 and 115. So 87 sits close to the biggest crowd of scorers, just on its lower side.

No. Mensa takes roughly the top 2 in 100, which means 130 or above on this scale. 87 is 43 points below that line, so it's not close. Mensa only accepts supervised tests anyway — online results don't count. Very few people qualify, and nothing in daily life requires it.

Scores move around. Even on professional tests, the likely range around 87 runs from 82 to 92. Sleep, mood and test quality shift it, and short online tests swing the most. A supervised test given by a psychologist gives the steadiest number, so treat any single online result as an estimate.
