The efficiency measure sure seems dangerously misleading. My SC high school didn't have the budget to replace broken tables (which were simply overturned until a handy-ish student managed to unsteadily prop them up) and sent seniors home home early via free periods to cover for a lack of teachers. Was that efficient? I suppose. Was it a desirable education? Not really.
