An IQ score of 74 falls into the Borderline range on the standard intelligence scale (mean = 100, standard deviation = 15). This score is below the typical range but within the normal distribution; often compensated by skill, experience, and practice.
What an IQ of 74 means
An IQ of 74 is around the 4th percentile, about 1 person in 24 at or below. Adults who score at this level work in a wide range of jobs, particularly ones with clear routines, practical tasks and on-the-job training. Vocational programmes that teach skills by doing rather than from textbooks often suit them well. Job performance depends heavily on experience, reliability and motivation, none of which an IQ test measures. If 74 came from an online test, remember that the result has a wider margin of error than a clinical assessment and may understate your ability.
Where does an IQ of 74 rank?
On a standardized IQ test, a score of 74 places you higher than approximately 4.2% of the population, which means most people score above this level. Intelligence scores follow a normal distribution — most people cluster near 100, and scores taper off sharply toward both extremes.
| Metric | Value |
|---|---|
| IQ score | 74 |
| Classification | Borderline |
| Percentile | 4.2% |
| Rarity (out of 1,000) | ~958 in 1,000 score this high or higher |
| Standard deviations from mean | -1.73 |
IQ 74 in numbers
- About 4.2% of people score below 74, and 95.8% score higher.
- In a room of 100 randomly chosen adults, about 96 would score 74 or higher.
- Another 6 points would move this score into the Low Average band, which starts at 80.
- Even on professionally administered tests a single result has a margin of error of about five points either way, so a measured 74 is best read as somewhere between 69 and 79.
On our free IQ test
None of the 3,834 people who completed our free IQ test between April and October 2026 scored exactly 74; 100.0% scored higher. People who choose to take an online IQ test are not a random sample of the population (our average is 114.5), so this shows where a score sits among other test-takers, not among everyone.

Which IQ tests produce a score of 74?
A score of 74 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 74
Scores between 70 and 90 are within the normal distribution but below the population mean. Many people in this range thrive in their careers and relationships — IQ is only one dimension of ability. Domain-specific skills, conscientiousness, practice, and social intelligence all contribute significantly to real-world outcomes.

| Below 70 | Extremely Low | ~2.2% |
| 70–79 | Borderline | ~6.7% |
| 80–89 | Low Average | ~16.1% |
| 90–109 | Average | ~50% |
| 110–119 | High Average | ~16.1% |
| 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.

Is IQ 74 considered good?
An IQ of 74 is below the population average, but IQ is a narrow measure — domain-specific skills, experience, and effort matter at least as much as raw score in real-world outcomes.
Can an IQ of 74 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 74?
An IQ of 74 corresponds to the 4.2th percentile on the standard bell curve — meaning it is higher than about 4 out of every 100 people.
