Note that getting rid of tailored instruction does not just "eliminate opportunity for accelerated math", it also makes it harder to access remedial math instruction promptly for those who need it. This is how you get students who can't quite grok negative numbers or fractions when they're in a frickin' Algebra I class. It absolutely hurts vulnerable students.

Of course the most common 'solution' is then to get rid of "advanced" stuff like Algebra as a graduation requirement altogether, which is an even clearer disservice to students and their surrounding communities.
