Not really, but...
I had a student in my high school classroom. SO smart and so self-directed. I had her quit doing the busy work the other kids had to do and do independent projects and so she would sit in my classroom and pull out whatever book she was reading. Sometimes it was work for a class, sometimes a novel. Meanwhile, she was doing college level reading for me. (The stupid school wouldn't move her out of the lowest level which is what that class was. Honors was "full".) She also worked well with others, even non-gifted kids, and made them feel like they had value to contribute to group projects.
I found out about a month ago (we're still in touch) that she went to Montessori through grade 6. I wasn't surprised and told her so.
