Costs money to equip a classroom with appliances and supply it with raw materials used in cooking - money that can be "put to better use" increasing test scores and such, because increasing test scores increases funding in the NCLB model - teaching people practical life skills is not rewarded.
You know what costs a lot more than equipping a single classroom with appliances (which are usually donated anyway)? Turf on the fucking football field. And get off the test score bandwagon. Test scores don't mean shit and shouldn't translate to dollars. We need to change all that mentality, specially when teachers teach to the test and only on how to get a better test score. We just need better teachers.
