No, you don't need to be an architect to be a CASp, but the exam fees are higher for non-architects.Interesting. Does one have to be a licensed design professional to become a CASp?
Well before the ADA, the University of North Carolina established the National Center for Barrier-Free Design, which had a program to certify or accredit (I don't remember what term they used) barrier-free design consultants. Whatever they called it, I had it. The National Center for Barrier-Free Design more or less evaporated after the ADA was enacted.
I understand that Texas now has their own access specialist program as well: https://www.tdlr.texas.gov/ab/rasexam.htm
