I did. I went as a sophomore. I was a good kid at home as well. I didnt get shipped off. I went because it offered an opportunity to have a better education.
I did ok to start. It was rough living pretty much on your own at that age. So much to worry about etc...
What I did at boarding school was much like college.
I think they need to transition kids into it though. Especially if they are going to college and living on campus.
I think by their senior year a kid at boarding should pretty much be able to self sustain themselves.
I was self sustaining at the age of 14. While I had meals provided, I have to figure out my study, sleep, sports schedule.
When I hit college, it was everything above with meals added.
I did much better than a lot of others who just got thrown to the fire.
I did way better than those "shipped" off for behavioral problems. Those kids just ended up doing worse. The got freedom and all hell broke loose.
Edit:
I wont do this to my kids but I will make high school much like what college will be like.
It is my job to prepare them for it. My kids are going to a private christian school, I shouldn't have that problem
