These tests designed for
- Adults (age 16+) of average or higher intelligence.
Which one first?
It is best to start with the AQ-10 as it is the fastest test, and then either the AQ 50 or RAADS-R if you score high on the AQ-10, or the CAT-Q if you do not. Regardless, it is advised to take the CAT-Q at the end. Bear in mind that some non-autistic individuals may score highly on these tests, so a professional assessment is advised.
