Why can't teens we make in other active households spawn as high school classmates?
That's really lame and requires mods to fix. A feature like this should already be in the base game.

I have a lot of played teens as well, sometimes multiple per family, and I have seen a couple of them show up at school while not active. For me, it appears to be pretty random and changes day to day, but the game does tend to pull in a lot of unplayeds and randos, and there really isn't a huge pool of students in the school on a single day.
