I’d recommend a search, as this question gets asked every few months and generally receives lots of replies.
JR is a big, diverse school with a wide range of academic offerings, including about 30 AP classes, and tons of activities and clubs. It’s extremely LGBTQ+ friendly (one of my kids is LGBTQ+ and loved their experience). Not sure what sort of arts your kid is into, but there’s a robust theater program and some interesting visual arts classes. Plenty of kids don’t play sports.
Check out instagram to get a sense of colleges; you can find the last few years’ classes by searching “jackson reed” and the class year. Kids go to state schools, SLACs, HBCUs, Ivies, etc.
Good luck!
