John, have you ever had your question answered? State licensure is variable from state to state. Most have gone the route of regulating the practice. Practice is defined in the statute. Actually, very few states specifically address voc rehab counselors. Most are counselor licensure and the work that voc rehab counselors do would fall within the scope of practice. Almost all that I know of require testing, specific curricula in master's program, lots of paperwork, and paying a fee. Whether one has or does not have a CRC is not a factor. Hope this helps.
