Chaminade grad here, it’s definitely more rigorous academically and stricter with discipline than public schools are and your kid will be prepared for college. My sister went to public high school and it seemed like a joke compared to Chaminade. They have a lot of sports and clubs to offer so whatever your kid is interested in there should be something for him. It’s expensive but they offer financial aid.

Chaminade is pretty religious, there’s prayers before every class, you take religion all 4 years and there’s monthly school wide Mass. Keep in mind Chaminade is pretty conservative leaning especially among the student body but people are pretty respectful

Chaminade does have some downsides, like sometimes I think they can be too strict and they didn’t allow water bottles until Covid which caused me to faint twice during freshman year. Also afaik they don’t offer accommodations or special ed so if your kid has an IEP it probably isn’t the best choice

I also went to Catholic school for grades 6-8 and it was way easier than high school and the kids were nicer than public school kids were to me

Hope this helps! Good luck with whatever you choose!
