If you're weighing Raven's Progressive Matrices against Stanford-Binet Intelligence Scales, the short answer is that they serve overlapping but distinct purposes. This page breaks down exactly how each test is built, who it's for, and when to pick one over the other.
Side-by-side comparison
| Raven | Stanford-Binet | |
|---|---|---|
| Full name | Raven's Progressive Matrices | Stanford-Binet Intelligence Scales |
| Year introduced | 1938 | 1916 (current: SB5, 2003) |
| Target audience | All ages, cross-cultural | Ages 2 to 85+ |
| Duration | 20–45 minutes | 45–90 minutes |
| Format | Paper or online, untimed or timed | Administered one-on-one by a trained psychologist |
| Scoring | Converts to mean 100, SD 15 via lookup tables | Mean 100, SD 15; full-scale IQ + 5 factor scores |
| Strengths | Nonverbal — minimal cultural or language bias; measures fluid reasoning directly | Widest age range of any IQ test; strong at both extremes of the distribution (very low and very high) |
| Weaknesses | Only tests fluid reasoning (one of several cognitive factors) | Less widely used in adults than WAIS; proprietary |
| Best for | Cross-cultural research, nonverbal assessment, fluid-intelligence measurement | Identifying giftedness in children, full-range cognitive assessment across the lifespan |
Raven in depth
Raven's Progressive Matrices — Nonverbal — minimal cultural or language bias; measures fluid reasoning directly. It's typically used for cross-cultural research, nonverbal assessment, fluid-intelligence measurement. Only tests fluid reasoning (one of several cognitive factors).
Stanford-Binet in depth
Stanford-Binet Intelligence Scales — Widest age range of any IQ test; strong at both extremes of the distribution (very low and very high). It's typically used for identifying giftedness in children, full-range cognitive assessment across the lifespan. Less widely used in adults than WAIS; proprietary.
Which should you take?
For most people, Raven is the stronger choice when cross-cultural research, while Stanford-Binet is better suited when identifying giftedness in children. If you want an instant starting point before committing to a formal test, our free IQ test gives you a calibrated baseline in under 20 minutes.

Frequently asked questions
What's the difference between Raven and Stanford-Binet?
Raven (Raven's Progressive Matrices) is best for cross-cultural research, nonverbal assessment, fluid-intelligence measurement, while Stanford-Binet (Stanford-Binet Intelligence Scales) is best for identifying giftedness in children, full-range cognitive assessment across the lifespan.
Which is more accurate, Raven or Stanford-Binet?
Both are well-validated. Raven: Nonverbal — minimal cultural or language bias; measures fluid reasoning directly. Stanford-Binet: Widest age range of any IQ test; strong at both extremes of the distribution (very low and very high). Accuracy depends on what you need to measure.
How long does each test take?
Raven takes 20–45 minutes. Stanford-Binet takes 45–90 minutes.
