I grew up and live in central Ohio and the schools here really are quite spectacular. We're moving, but we've had a helluva time deciding where to go because our standards are apparently quite high for schooling. We've always known we had good schools, but we didn't realize how much we had taken for granted until we started looking elsewhere.
Columbus City Schools are garbage (corruption, all kinds of other factors), but the suburbs are outstanding. My wife and I graduated from Dublin City Schools, which were/are excellent. Our kids go to Olentangy Local Schools which, last I checked, were ranked in the top 20 by various metrics across the country. Upper Arlington is also nearby, which is also a typical top 20. My son is gifted, and the opportunities he gets are practically endless. We have virtually zero crime, teachers are amazing, etc. The only downside is you end up very "insulated" here, and I've noticed this whenever I travel to other places. Sometimes it's an adjustment.
But graduation rates in these suburbs are usually 96% - 99%.
