Re: FLL as a school class?
Quite a few schools in this region have a fall-season (or all-year) robotics course, and participation on a LEGO League team is part of the curriculum.
Due to FIRST's "10 kids per team" limit, a school class is going to have to sponsor multiple teams. I see that quite a lot at tournament - kids from the same school on multiple teams, all with the same color t-shirts.
