@CateCAParent – agree with your question, so I’m pulling it out here to give it extra airtime for the OP:
What are you looking for a boarding school that you can’t get at home?
That one question will help sift through a bunch of options.
Why?
Because if the answer is: you simply cannot find a class that you can’t get an A in with your eyes closed, then that points to a certain bucket of schools. (I suspect this is not your reason, but just an example). Or, you need to find world-class math classes because you are too advanced in math.
other answers: living in community, study abroad, specific courses/languages not offered at home, the ability to do more activities without needing to drive in between, certain ECs or sports not available at home (like crew, or ice hockey or whatever).
So if you can be as clear as possible to explain what you are looking for that you can’t get at home – both for yourself and for us to help with suggestions – I think that would be incredibly helpful. (Also: it will help you in fit, which means you will have stronger interviews, and more importantly: it will help match you up with schools where you would be happy).
both my DD’s are volleyball players so I dare say that I’ve got my arms around a LOT of schools that offer VB.
