Problem: I am doing research on 3 different types of assessments used to diagnose Autism Spectrum Disorder (the Autism Spectrum Rating Scale (ASRS), the Checklist for Autism Spectrum Disorder (CASD), and Gilliam Autism Rating Scale- Third Edition (GARS-3-) and am looking for information on each of them and need assistance.
I am looking for a description of the test materials, the cost of the tests, the administration times, what types of formats are available, and if the tests are feasible in an educational (school) setting.
Any help would be appreciated.
