SD didn't write with an attitude, so I guess that's me! I just said this isn't an experiment, it's just feeding kids. If they're not getting breakfast at home, why not the school? Don't elementary schools have cafeterias any more? For getting kids together in one place to give them breakfast, the school cafeteria is the logical place, since it's already there and it's where the kids are. If the kids can't arrive early, serve them when they get in. Heaven's sake! As far as an experiment, haven't some districts been doing this for about forty years?
Maybe the kids parents both have to get to work at 6AM. Maybe they got home from the night shift and are sound asleep. Maybe breakfast is too hard for them to manage. Who knows? But the kids ought to be fed breakfast, and school is the logical place.
