May as well give up on the school, it can't be changed. Schools generally start out the best they will ever be, then get worse over time. Once a school establishes itself as decent, everybody wants to go there, including the problems, and well, what goes in comes out. No school is inherently 'good' or 'bad', they are all products of the parents/students that attend.
I've yet to see one public school in Starkville's position that actually got better over time. You have some like Brandon who started out decent, and are now seeing the rise from becoming a growing Jackson suburb. But again....it was never below average like Starkville.
So, if you don't want to pay for Starkville Academy, better hope the kids can adjust to Starkville High and find their niche. Else East Webster gonna keep growing. But this isn't some sprawling urban area, so this really doesn't help Starkville all that much and prevents some needed growth.
Of course, my idealist mind tells me that there could be a group together that isn't scared of Starkville High, and bands together and keeps support high there. But I know that's delusional thinking. So my practical side says, accept that the public school situation is what it is, and Starkville Academy is where we need to invest. Heck, even in areas with strong public schools, you're seeing private schools pop up.
Best thing to do would be for parents to decouple their real estate choices from the public school systems. But I recognize this takes a shift in overall population thought, which happens slowly. People are waking up, though.
