<p>Concord Academy is one school that I think handles the boarding/day student issue beautifully. The school is 50/50 boarding/day, but most important is that boarding students are not allowed to return to their dorms during the day (from 8-3) thus making all students day students in effect. At the same time, day students are welcome to stay for breakfast and dinner and thus they mix easily and frequently with the boarders. Numerous weekend activities (no Saturday classes) make for lots of mixing as well. I have known day students in many other schools around here (greater Boston) who feel left out of the boarding community and agree with the sentiment that it might be better to be at a day school rather than a boarding school.
I do not think you proposed move, Joyhuffes, will worry many schools. You will naturally find that there is less parental involvement at high schools of any kind. That said, all schools in this region rely on parental volunteers and support (and not just for $$). PM me if you’d like more info; I know this area very well.</p>
