That’s similar to my state. You start with an initial certificate that is good for four years while you complete some requirements, such as a mentor program. Then you have to upgrade (which includes a fee) to a career certificate. That career certificate is good for 99 years though, so no one is paying a fee ever again after that, unless they want to add on new areas of certification. In my other state, we have the requirement of paying to renew every five years. Even though I don’t expect to ever work there again, I continue to pay in order to have it as a backup plan. They’ve changed the requirements for licensure since I earned mine, and I don’t want to ever have to take another test or additional coursework, should I find myself in the unlikely situation of needing to work there. So, it’s just easier to pay $50 every five years and know that I’m good to go should I decide to work in the state again.
