If you're weighing Montreal Cognitive Assessment 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
| MoCA | Stanford-Binet | |
|---|---|---|
| Full name | Montreal Cognitive Assessment | Stanford-Binet Intelligence Scales |
| Year introduced | 1996 | 1916 (current: SB5, 2003) |
| Target audience | Adults (especially 55+) | Ages 2 to 85+ |
| Duration | 10–15 minutes | 45–90 minutes |
| Format | Paper or digital; brief screening test | Administered one-on-one by a trained psychologist |
| Scoring | 0–30 points; 26+ considered normal | Mean 100, SD 15; full-scale IQ + 5 factor scores |
| Strengths | Quick, validated screening tool for mild cognitive impairment (MCI) and early dementia | Widest age range of any IQ test; strong at both extremes of the distribution (very low and very high) |
| Weaknesses | Screening tool, not an IQ test — does not produce an IQ score | Less widely used in adults than WAIS; proprietary |
| Best for | Cognitive screening for impairment, not aptitude measurement | Identifying giftedness in children, full-range cognitive assessment across the lifespan |
MoCA in depth
Montreal Cognitive Assessment — Quick, validated screening tool for mild cognitive impairment (MCI) and early dementia. It's typically used for cognitive screening for impairment, not aptitude measurement. Screening tool, not an IQ test — does not produce an IQ score.
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?
Note that the MoCA and MMSE are cognitive screening tools, not IQ tests. They're designed to detect impairment, not measure aptitude. If you want to know your IQ, use a test like WAIS, Stanford-Binet, Raven, or our free IQ test. If you're concerned about cognitive impairment in yourself or a family member, talk to a physician — the MoCA and MMSE are starting points, not diagnoses.

Frequently asked questions
What's the difference between MoCA and Stanford-Binet?
MoCA (Montreal Cognitive Assessment) is best for cognitive screening for impairment, not aptitude 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, MoCA or Stanford-Binet?
Both are well-validated. MoCA: Quick, validated screening tool for mild cognitive impairment (MCI) and early dementia. 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?
MoCA takes 10–15 minutes. Stanford-Binet takes 45–90 minutes.
