MMSE in depth
Mini-Mental State Examination — Widely used, very quick. It's typically used for quick clinical cognitive screening, not iq measurement. Criticized for low sensitivity to mild impairment; not an IQ test.
Wechsler in depth
Wechsler Intelligence Scales — Dominant professional IQ battery worldwide. It's typically used for any setting requiring a rigorous, professionally-administered iq measure. Only available through trained psychologists.
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.
