We did partial homeschooling with one of ours for a couple of years, with some success. Mostly specials. A couple of my sibs did cross registration in elementary and secondary. They were both in situations where the campuses were adjacent to each other. Oh, and I did middle/high, again on connected campuses. All of those experiences were net positive, but I think outcomes are highly dependent on the child, and the administrators and teachers involved.
