Yep. Funny, then, that some schools clearly hire and keep better teachers than other schools. If performance and ability couldn't be evaluated, all schools would be equally likely to employ crappy teachers. $40K/yr private schools in NYC would be just as likely as the city's worst public school to hire and keep a deadbeat. If teaching skill was that hard to evaluate, the high end private school wouldn't know if a teacher was any good, and would be incapable of selecting and keeping better teachers than any other school.
