I have a niece who lives in the Bronx, near the Botanical Garden. Technically, I suppose, it is Riverdale, but not the fancy part. She and her H both went to private schools in other states. Their oldest is in the G&T program in her public school. She is the only white girl in her class. (All the kids in the class are in the G&T program.) According to the prevailing narrative, this should not be. Interestingly, they had a choice between this school and another that they were in the regular zone for. That school is, I believe, whiter, and actually has higher overall scores despite not hosting a G&T program. I don’t know how the G&T program scores compare. It’s an interesting situation. It remains to be seen what they will do with their two younger children, how they will test, etc. And what they will do about middle school. And whether this pressure will eventually drive them out of the city.
NYC has an astonishing array of options. Most places don’t have the population density to support it.
