If you're weighing Montreal Cognitive Assessment against Wechsler Intelligence Scale for Children, 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 | WISC | |
|---|---|---|

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.
WISC in depth
Wechsler Intelligence Scale for Children — Widely used in schools and clinics for children. It's typically used for child cognitive assessment, giftedness identification, learning-difference evaluation. Adults need WAIS; requires trained examiner.
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 WISC?
MoCA (Montreal Cognitive Assessment) is best for cognitive screening for impairment, not aptitude measurement, while WISC (Wechsler Intelligence Scale for Children) is best for child cognitive assessment, giftedness identification, learning-difference evaluation.
Which is more accurate, MoCA or WISC?
Both are well-validated. MoCA: Quick, validated screening tool for mild cognitive impairment (MCI) and early dementia. WISC: Widely used in schools and clinics for children. Accuracy depends on what you need to measure.
How long does each test take?
MoCA takes 10–15 minutes. WISC takes 60–90 minutes.
