Where are you getting state counts, and what do they mean here?

As far as I know, most states have procedures for licensing several of these categories, and a couple more besides (Licensed Marriage and Family Therapist, for example).

The state counts are from the linked website. (As someone from Europe I have zero idea about any of this. I was just fascinated by the "TLAs".)
