I am at a loss as to why a school district would build a building which did not provide adequate PE space, since PE has been required forever...Sure, if you have a 100 year old elementary, the cafeteria/gym is probably inadequate, but adapt your course to the space...But if your new high schools (Plainfield) can afford pools, your new elementary schools can certainly afford basic gym space...
Alternative pe should be the choice - athletes should have a training course available, lifting & training for their sports, while non-athletic types could do lifestyle activities like walking, calisthenics, etc...I've seen outdoorsmen oriented pe, with camping, hiking, etc. focused upon. Don't tell me "we don't have enough gym space". Going for a walk doesn't require any expensive space or equipment...
My alma mater is listed as considering a waiver for some students...Don't eliminate PE, maybe pull kids out for help if they need it, but leave them in PE...I took a waiver starting second quarter my senior year, as I was taking probably the most difficult academic schedule possible then...despite playing hoops, playing baseball & running track I put on a bunch of weight between dropping pe & the end of the school year...In retrospect, waiving pe was a huge mistake for a study hall...
