With so many psychological tests online being unscientific garbage, it’s nice to have a place online that carries reliable tools analogous to those used by professional scientists and psychologists. CORE is a very impressive project, and probably the best IQ test publicly available at time of writing.

I enjoyed taking the CORE test and I hope to see the evolution of it, hopefully this project gets to the point where it's professionally realised! I'm not sure what the 1 star reviews are on about though, I'm guessing they were told they have a low IQ lol

i've seen many website about iq test and this is the best without a doubt, all the test are correctly normed, and you can even read the manual of the core test.

CognitiveMetrics offers something genuinely rare in the online cognitive testing landscape: a battery that takes psychometric rigor seriously. The CORE in particular is impressively thoughtful in design, with subtests spanning all major CHC domains and proper attention to g-loading and reliability. The dashboard is clean, the score reporting is transparent (composite g-loading, SLODR, confidence intervals), and the methodology is documented openly enough that an interested user can actually understand what they're looking at. What stood out most for me, though, was the support. As a non-native English speaker with a documented visual condition (keratoconus), I had specific concerns about which subtests were validly measuring my abilities versus capturing construct-irrelevant variance. The team responded very patiently to my multiple requests, accommodated methodologically reasonable adjustments to my dashboard, and engaged seriously with the underlying psychometric questions. That kind of responsiveness and support is unusual. Really an excellent work, simply.

CORE is the best test out there.
Tanner
By far these are the best made tests I've seen online so far. My score on the CORE and AGCT tests were comparable not only to each other but more importantly to a test proctored to me in person by a psychologist. The only thing is that it'd be nice if we could see our past attempts to compare across time.
