I wasn’t going to reply any more, but I appreciate this post of yours. I’m getting more of a good-hearted wanting to protect parents and children feel, which is making me feel better. Here’s what I would say:
I know the type of public high school you’re talking about. I’m a product of what’s arguably the top-ranked large, comprehensive public high school in my state (by Niche.com, by data from the state board of education, and just the common knowledge of the local populace).
I agree with you. A student’s success or failure isn’t just based on teachers. Is it even primarily based on teachers? That’s one of the head-scratchers in all of this. In a basic model, you’ve got the family / the student / the teachers all playing a role in the student’s success or failure. But is it even possible to divvy out contribution or blame to each party?
This is why basic political proposals linking teacher pay to performance quickly reveal to some a politician who is out of their depth. It’ll just cause even more teachers to flee for the suburbs. A great teacher who teaches to a large population of undocumented families where the children are working is going to have a tiny salary compared with a lazy teacher who teaches to a community with a country club.
When I read your post, to me it continues to make the case for private schools.
My parents paid more than they were comfortable with (borrowing from relatives, cutting budgets) to get the kids into the highly-ranked school district. They “invested” in our education. Private school parents are doing the same thing in an even more “turbocharged” way.
In the system of families / students / teachers, even if the teachers are the weak link, they’re paying for excellence from the other families and students. When the teachers were lacking at your top-ranked public school, you found excellent students to learn from. And the student population had computers and internet access and knew of the existence of Khan Academy. That’s part of the private school deal. There are so many supporting points of excellence, it’s less likely for a student to fall on their ass if one piece is lacking.
But on the teachers being the lacking/lagging piece. Each school is very much its own entity. In general, at a public high school (even top ranked ones), student ratings of teachers matter less. I mean, the parents and students are getting a deal: education included in taxes. What I’ve seen in the private school system is that student ratings matter much more. A teacher who cannot get their ratings up after a probationary period is not going to have their contract renewed, or there will be some explanation, such as there are simply too few teachers in the subject area and beggars can’t be choosers.
