It depends on the district. 20-1 is not state mandated. Most schools that could afford to, have kept their 20-1. Some have 20-1 in 1st grade and 9th grade since the studies show that is where it counts - others don't have it at all. Unless it is a lottery school, I can't imagine telling a parent we were full. Schools get their money based on enrollment! Schools that run off the lottery system can tell you the school where the "other" kids go that is usually very close. Good luck!
