In the near future maybe we could have a Honors Roll. Or a special way for recognizing students who excel in their classes. Although house points are reward enough, perhaps we could recognize a few students for their hard work and dedication to learning.
I don't know if there already is one, but a second idea might be to have a club similar to Juniors Honor Society. A club that accepts hard-working and intelligent students.. though most students at Hogwarts are already intelligent and hard working.
This is just an idea..
