International Cognitive Ability Resource

The International Cognitive Ability Resource is a public-domain assessment tool which aims to encourage the broader assessment of cognitive abilities in social sciences research. The collaborators working on this project believe that the best way to achieve this aim is by making it easier for research scientists to employ flexible and unrestricted measures which have been well-validated against one another.

We hope this site will further this aim by:
distributing the resources which are currently available (the existing "item types")
providing psychometric information about these resources
encouraging researchers to develop and contribute item types for use (and validation) by others
