GBS Grad Night is a parent-planned and parent-sponsored event hosted by the GBS Parents’ Association Grad Night Committee. The annual event provides a fun, supervised celebration giving graduates one last night together. 

Glenbrook South High School and Glenbrook High School District 225 assist the Parent’s Association with communicating about the event but do not sponsor it.
