A Global Resource

The International Neuropsychological Normative Database Initiative, or INNDI, aims to develop regression-based norms that enable their user to adjust cognitive test scores for a test taker’s age, sex, education, country of origin, and language.

INNDI currently is accepting normative data for selected cognitive tests that have been collected in any country. The resulting databases are being used to derive regression-based norms for each test. User-friendly look-up tables for each test will be published in scientific journals as a free global resource.

INNDI databases and normative tables will enable users to benchmark a person’s test performance against that shown by healthy persons of similar age, sex, educational, cultural, and linguistic background.
