I’d also note that teacher quality probably correlated heavily to funding and “lack of social challenges” in the student body. Schools with worse parental education attainment levels, higher poverty rates, discriminated against classes and other demographics, kids exposed to more social ills, etc will lead to worse teachers picking that as their job opportunity. Why? Because most people prefer a job that’s not extraordinarily difficult in ways they’re not compelled by. There will always be a set of teachers that are compelled to be a great teacher AND a great social worker, but you have to expect that joint distribution is pretty small relative to the staffing needs.
