For teaching, it’s not a bad idea to look at schools in state where you want to teach. You definitely don’t want debt for teaching degree. If you want to stay in Texas, that’s where I’d focus my search.
If you decide to go elsewhere, just be aware of different certification rules and be sure you’ve satisfied the requirements of state where you wish to teach. Any good education program can advise you on that and, of course, the state departments of education in applicable states.
