Anyone who wants to ban standardized tests is truly delusional considering they are the gateway to most professions, but basing teacher pay off of them is complicated. No one would want to teach in low performing schools at all.
Which is exactly why those teachers who have the skill set to improve the educational outcomes of low performing students due to their socio-economic disadvantages that make their educational experience more difficult, need to paid a lot more money, and those teachers that lack that skill set need to be removed from such classrooms. That along with restoring discipline in the classroom, are in my view the main two things that really matter.
I have no objection whatsoever, and indeed consider it to be the top social priority, to spend a lot more money on the education of this cohort of students, provided that it really produces an improvement in educational results. Right now, we tend to focus on just inputs, rather than focusing on the output. The biggest waste of money of all, is having fancy buildings, and hordes of administrators.
