It will be difficult for him since his major is history and that degree is quite common. Can he get an additional certification in math, science or special education without too much trouble? Men are desired in elementary education as well. That would improve his chances. Also coaching and sports medicine experience/certifications would help. The very best advice I can give to anyone trying to secure a teaching position anywhere is to get bus driver certified in the state you are applying in. On paper, he's just another name but principals always need a handy fill in bus driver so that would be the candidate he/she calls ahead of others applying.
I loved working in the small county system of Lincoln (PO Box 400, Lincolnton, NC 28093) and it's a great little system but, if he doesn't LOVE kids, they don't want him. We didn't pull in the big bucks like Charlotte-Meck but COL wasn't as high there either. It's located on the western shores of Lake Norman, northeast and easily accessible to metro Charlotte, Gastonia and Hickory.
