A friend who teaches high school physics was over for dinner last night. He recently lhad to leave his current position at a public school due to budget cuts and had just finished finding a new job. He reported on the differences in hiring procedures at the public versus private high schools where he interviewed.
At the public schools, the interviews lasted an hour. The interviewer checked some basic facts, such as whether my friend had experience in teaching the relevant courses, and whether he was certified. The public schools did not ask him to guest teach a class, or meet with other faculty, or make any serious attempt to get to know him or check they quality of his teaching. They seemed interested in filling a slot. Period.
At the private schools, the interviews lasted a day. My friend guest taught in several classes. He met lots of people. He got to know the school, and the school got to know him. The schools seemed genuinely interested in determining whether my friend is a good teacher.
My friend got offers from both publics and privates. Guess which one he chose.
