In 1962, due to overcrowding at Glenbrook North, Glenbrook South High School was established. It underwent a dramatic expansion in 2002 adding dozens of classrooms, revamping the music and performing art facilities, and reconfiguring the parking lots and athletics fields. During the summer of 2007, Glenbrook South updated six science classrooms from the 1960s and reconfigured two others to create full-size science classrooms. The Dean's Office, and Student Activities Office were also renovated. A new Food Court was constructed along with a Student Activities Center that was created by reconfiguring the faculty lounge. Construction at GBS was completed with the addition of a practice gym, which increased PE capacity and a new pool with handicapped access, eight lane capacity and a diving depth of fourteen feet. A new fitness center opened in May 2008 and the former weight room was converted into two health classrooms, a driver education classroom and a Health/Driver Education office. Today, Glenbrook South High School, along with Glenbrook North, are noted for their outstanding curriculum and quality of education, having been repeatedly named to a variety of best-in-the-nation lists. For example, as part of the First in the World Consortium, GBS and GBN students scored first in the world in international math & science testing.[7]
