I don't have any personal experience with your problem (I don't even know what CACREP is, but I get that it's an accreditation of some sort), so I'm not sure what to do? Does Louisiana have any ideas for you on how you can get those 3 hours or how you can make up for not having CACREP? Alternatively, are there other places you can practice (in private schools, maybe?) without that state certification? Or any emergency/temporary certification?
I'm sorry, I wish I knew what to say. I'm glad you're appealing. It's hard to make up for not having the accreditation required.

Let us know how the appeal goes!
