I passed the

CPA Certification

I suggest checking with your particular state's board of accountancy. There's contact info here: http://nasba.org/stateboards/
I passed the CPA exam in 1994 in Kansas and was considered certified but not licensed. When I started working for my current employer, they wanted me to get licensed. We can use this as a recruiting tool to say that individuals who pass their CPA can get licensed by working in Internal Audit. Got my Nevada license about three years ago.
I did not have to re-take the exam, but did have to take 156 hours of CPE on my own time, have my work evaluated by an independent party, and presented before the Board of Accountancy.
Each state's requirements are different, so checking with your State Board of Accountancy is your best best, as Charles noted above.
