This has been discussed in other threads but since I'm adding to my fic, I might as well get it right. Anyway, which schools would Karen and her friends go to after Stoneybrook Academy? Stoneybrook Middle is too far away since Watson and Elizabeth pay extra to send Kristy.
Kelsey middle school might be an option, but it's not private. The Miller School seemed to be an option, but Dana and Adam are still relatively young (8&6), and it might be k-12.
Then I would assume they would go to Stoneybrook High for high school. It's the only one in the area.
