Terms of use
Free to use, no warranty, and definitely not medical advice.
Not medical advice
CognitiveDrill provides measurement tools for interest and practice. Nothing on the site is a medical device, a clinical assessment, a diagnosis, or a substitute for professional advice.
No score here can show that you do or do not have any condition. If you have concerns about your thinking, consult a qualified clinician.
Use of the site
The tests are free to use and need no account. Do not attempt to disrupt the service.
Do not use automated clicking or typing software against tests that measure human performance. It makes our future figures worse for everyone, and it makes your own score meaningless.
Some tests involve repetitive movement. Stop if anything hurts.
Accuracy and liability
The site is provided as is. We take accuracy seriously, and we publish our measurement limits on the methodology page.
But timing in a browser depends on hardware we do not control, so we make no warranty that any figure is exact. To the extent permitted by law, we accept no liability for decisions made on the basis of a score from this site.
Content
You may quote our written content and published figures, with attribution and a link. You may not copy the tests themselves wholesale. Cited research belongs to its authors and publishers. Questions: [email protected].
