This is all around a bad idea. Not only because of the scenario you mentioned but because modern “families” look different today. Zones split right down neighborhoods… even living one block away puts you in another school.
That being said, school choice isn’t that helpful. The most segregated school district in the US is NYC, which has had citywide school choice for a long time.
> In 2018 in New York, 90% of black students attended predominantly nonwhite schools, while Latino student enrollment in predominantly nonwhite schools has remained roughly stable (84%). Almost two out of three black students and over half of Latino students attend intensely segregated schools, where less than 10% of student enrollment is white.
Maybe the “best” districts do what was done to me when I was growing up and purposefully test me harder, then get upset when I passed. Trying to justify that I didn’t belong but I ended up scoring a 99.9% on their stupid aptitude tests.
There’s a whole host of reasons why someone with choice still chooses shitty…
