I can’t believe the public would even give ear time to an article that is written by someone with no experience in a profession. As a teacher I would never try to say how bad doctors, lawyers, or Silicon Valley engineers should be evaluated. Send a few of these reformers to my classroom and let them see how easy it is to teach! I don’t think they could handle it. My kids would rip them to shreds. Teaching is an art and the curriculum is only part of it. Bad teachers eventually weed themselves out. Also, so many administrators are very inexperienced because long term teachers are not crazy enough to go into that aspect of the field. I have, but missed the classroom. If an administrator wants to get rid of a under performing teacher, they can. But they’d ave to do the work. If a school is keeping bad teachers, that’s on the ad team! Don’t believe me, try my job for a while! If you can hang!
