I disagree. There are known “good” and “bad” school districts. The known good school districts have better teachers and teaching methods.
This is not about the bell curve, it’s about a lot of US schools not actually teaching students successfully.

Some schools being above grade level has nothing to do with teaching methodology, and everything to do with student composition. Smart people who raise their kids to do well in school move to neighborhoods with better schools, which raises the grade levels.
Ex: I went to Bronx Science, a specialized high school in NYC where 98% of the students are above grade level and go to college. The principal at the time was known to be an obvious subject of nepotism and generally made poor decisions often. The guidance department was a joke. Teachers were above average because schools full of smart kids attract smart teachers, but not so amazing that they'd make up for kids who started below grade level if there were any.
My wife actually went to the same high school and got depression, she dropped out of BX Science and went to a much lesser rated school. The teachers there were actually better in many ways (more organized, better processes, really useful classes on work skills and stuff were available for seniors due to grants) but the students were still generally below grade level and less than 1/3 went to college according to the stats. She was effortlessly at the top of her class even though she was severely depressed and missed days all the time.
Of course tracking is a good idea.
While I mostly agree, we shouldn't underestimate the destruction that can be wrought by a bad teacher.
