My local elementary school has 3 classrooms per grade. If we broke the year into quarters and made each student attend 3 out of 4 quarters, what you'd end up with is more efficient use of school facilities making up for a slightly higher teacher cost. Probably.

I think before we do rolling quarters moving to a year round schedule would do more to improve student performance than the more granular age groupings. Could also just group the kids into however many classrooms are in each school to do both.
