The ARC designs tests, evaluates and validates them, and then makes them freely available to the research community or for clinicians. You can download them below provided that they are used for research purposes and not for commercial use, and provided due acknowledgement of ARC as the source is given.
Our tests are not diagnostic: No single score on any of our tests or questionnaires indicates that an individual is autistic. Diagnosis is made on the basis of a clinical assessment including using clinical judgement. If you are concerned that you, or a friend or relative, may be autistic, please discuss these concerns with your GP or family doctor or ask the National Autistic Society (NAS) or equivalent charity in your country, for advice.
If you have translated any of the ARC tests, and are happy to post your translation on our website, to be used by other researchers, please contact us. We give full credit to the translators.
