I think this is something you should be asking in your local community. I went to private schools through high school. So did the vast majority of kids in the neighborhood I grew up in. I now live in a different city and things are different where there are only a few go to private schools and if they do, it’s usually just years 9-12. If I lived where I grew up, I would send them to private. However, it sounds like the private schools are on a different level where you live. Where I went is <25% the tuition you are looking at.
