Summary:
Bannockburn, Illinois, has one listed school, Bannockburn School, serving kindergarten through grade 8 and enrolling 165 students, so there are no other local schools to compare it with.

There is no separate local top or bottom school: Bannockburn School is both because it is the only one listed.
