Welcome to GBS Academics


Excellence is the goal of both students and staff at Glenbrook South High School. The instructional program is designed to offer the greatest possible flexibility in meeting the educational needs of a diverse student population.

Glenbrook South prides itself in its expansive offerings through the areas of the four A's: Academics, Arts, Activities and Athletics.

This page serves as a hub for all things Academics-related; however, we realize there is often overlap with Activities and Arts. We encourge you to explore those department webpages as well.
