I am doing research on the following tests related to Autism Spectrum Disorder: ASRS (Autism Spectrum Rating Scale), CASD (Checklist for Autism Spectrum Disorder), and GARS-3 (Gilliam Autism Rating Scale- Third Edition).

I am trying to find information on the training, education, and/or skills required by the test user to administer, score, and interpret the test.

Any help would be appreciated.

Thank you
