This is just too good. A tickmark with an explanation. And there's further explanation on the NASBA website:
This statistic is derived from the national database of CPAs, the Accountancy Licensee Database (ALD), and is made up of official Accountancy Board data that is currently aggregated from 51 of the 55 CPA licensing jurisdictions. It represents the total number of individual CPAs that are considered to be in an "Active" status by their respective Boards, a majority of which can be matched across state lines to assure licensees who are licensed in multiple states are only counted once.
Just for fun, I invite anyone who is willing, able and a little bored to write their imaginary audit opinion for NASBA's reported CPA popluation. Seems like a perfectly good way to waste some time.
