The elementary schools in general are fine. Some are excellent. I could help you locate tithe right area. Middle Schools in general suck, but there is a lottery system so you can get into better schools.
High schools are pretty good if you're in the right area. The commute into Nashville isn't bad if you choose a nearby county, which would offer the best
solution for schools. (Robertson, Cheatham, Sumner, and Williamson counties) again, elementary schools are good, so you would be fine for awhile anyway.
