Is a state certification required to start working at a hospital?

So I have to move states last minute and I'm trying to get my EMT cert for Texas, but apparently, it's required to get CE hours and take a jurisprudence exam, and I just don't have the money to pay for it right now. Is it possible to get a job at a hospital (at least in Texas) before getting your state cert as long as you have the NREMT?
