What does an IQ score of 111 mean?

An IQ score of 111 falls into the High Average range on the standard intelligence scale (mean = 100, standard deviation = 15). This score is above the population average — about one in four people scores at this level or higher.

Where does an IQ of 111 rank?

On a standardized IQ test, a score of 111 places you higher than approximately 76.8% of the population. Intelligence scores follow a normal distribution — most people cluster near 100, and scores taper off sharply toward both extremes.

Metric	Value
IQ score	111
Classification	High Average
Percentile	76.8%
Rarity (out of 1,000)	~232 in 1,000 score this high or higher
Standard deviations from mean	0.73

Which IQ tests produce a score of 111?

A score of 111 can be produced by any standardized intelligence test that uses the mean = 100, SD = 15 scale. The most widely used tests include:

• Wechsler Adult Intelligence Scale (WAIS) — clinical gold standard for adults.
• Stanford-Binet Intelligence Scales — oldest continuously-used intelligence test.
• Mensa admissions test — used by the Mensa society for membership selection.
• Cattell-Horn-Carroll (CHC) tests — most theoretically grounded modern framework.
• Our free IQ test — instant online estimate with the same scaling.

How to interpret an IQ score of 111

Scores in the high-average to superior range are associated with strong performance in educational and analytical settings. People at this level often report that unstructured problem-solving and abstract learning feel relatively natural, though domain expertise still requires deliberate practice.

IQ 111 in Context

IQ Range	Classification	Population %
Below 70	Extremely Low	~2.2%
70–79	Borderline	~6.7%
80–89	Low Average	~16.1%
90–109	Average	~50%

120–129	Superior	~6.7%
130+	Gifted / Very Superior	~2.2%

Factors That Influence Your Score

Your IQ score reflects a combination of genetic potential and environmental influences including education, nutrition, health, and the testing conditions themselves. Factors like fatigue, anxiety, unfamiliarity with the test format, and even the time of day can all affect performance. A single test score should be viewed as an estimate, and scores can vary by several points between testing sessions.

Compare the major IQ tests

Which test produces the most accurate score depends on what you're trying to measure. These head-to-head comparisons break down the differences:

• WAIS vs Stanford-Binet — the two clinical heavyweights compared.
• Mensa vs WAIS — entry-test speed vs full clinical assessment.
• Stanford-Binet vs Mensa — which one actually gets you into Mensa.
• CHC vs Wechsler — modern cognitive framework vs the classic.
• Raven vs Cattell — non-verbal alternatives for cross-cultural testing.

Frequently asked questions

Is IQ 111 considered good?

An IQ of 111 is within the average range — where most of the population scores. "Good" depends on context: IQ is one factor among many that contribute to life outcomes.

Can an IQ of 111 change over time?

IQ scores are relatively stable in adulthood but can shift modestly with education, engagement, sleep, and health. Short-term factors like stress and fatigue can move a single test result by 5–10 points in either direction — which is why we recommend comparing results across multiple sessions rather than reading too much into any single score.

What percentile is IQ 111?

An IQ of 111 corresponds to the 76.8th percentile on the standard bell curve — meaning it is higher than about 77 out of every 100 people.
