GAAP stands for Georgetown Admissions Ambassadors Program, and is a large volunteer student organization representing hundreds of Hoyas across schools. Although it is not directly involved in the admissions process, GAAP plays an integral role in welcoming prospective and admitted Hoyas by hosting panels, GAAP weekend, and acting as a resource for incoming students. 

The Georgetown Chimes was founded in 1946 by Francis E. Jones, a graduate student who had served in the Pacific War. Jones wanted to create a group that "emphasized brotherhood and friendship through harmony," which eventually became the Chimes, named after the bells hung on the South Tower of Healy Hall.

Gracenotes was founded in 1980 by Sue Vrana and initially was an all-women's a cappella group. The group started off as a quartet, whose repertoire included 40's and swing style music.

The Georgetown Free University (GFU) was created by two juniors, Richard Rosenblatt and Reese Fullerton, in fall 19671.
