According to the Indiana DOE Compass, Northview HS's feeder middle school has larger classes, which would bring Northview HS's enrollment above 1100 within 4 years, and closer to 1200 after that.
Terre Haute North HS has under 1700 students this year, putting it on parallel with Bloomington South for enrollment. Martinsville's enrollment will be closer to 1200 in less than a decade; BNL will be in the same situation. All of the schools in my proposal have, or will have, more in common with one another than with anyone else.
