Public schools can't allow kids being held back for non-academic reasons for no other reason than they'd have 50 kids a year being held back if crazy parents were allowed to. That would lead to classroom overcrowding, pressure on an already crushed budget etc..Can't blame the public school administrators for telling people to send their kids to a private school if they want to do this. With the financial strains that nearly every public school is dealing with - they are not the right environment, nor is it their mandate/charter/responsibility to provide a platform to incubate better lacrosse players.
