The Ohio Department of Rehabilitation and Correction accepts C.O. applications on a regular basis. You can go to their website to get more information on the selection process and benefits. Hopefully, they can answer all your questions. Although they don't accept lateral entry from other D.O.C's, the experience is a major plus in getting hired. They sponsor all their trainees through their academy at Orient, Ohio. Plus, you receive full salary and benefits while a student there.
Just get on google and type in odrc or ohio dept of corrections, and you'll get a link. Good luck.
