Any assumption that BPQA keeps all of this money is not correct. The amount retained by BPQA has not changed since 1991. Licensure fees vary widely among the state licensing boards. Some boards, like the Maryland Board, must reimburse their states for rent, postage, the cost of administrative hearings, the salaries of their prosecutors, etc. In other states, these expenses do not come out of licensing monies.
Some states retain monies obtained from fines.
In Maryland, fines against medical licensees revert to the state coffers.
