This has already happened in NY.
What the NYT article omits is that the elimination of advanced classes has been preceded by a couple of decades of highly restricted availability. 15 years ago (shit I’ve gotten old), when I lived in nyc_borough, there was precisely one elementary school honors class for the entire borough. 30 spots for the entire borough. I didn’t bother to wait and see if my kid managed to get a spot, we pulled her out and stuck her in private school.
