Since opening to the public in New X-Men (1st series) #117, the X-Mansion has been the frequent home to a large cast of mutant students, too many to fully name and count. The Xavier School for Gifted Youngsters had roughly 100 students operating in multiple training squads until M-Day brought them down to only about two dozen students. The school was closed after Messiah CompleX, although many students eventually made their way to San Francisco and Utopia as either active or reserve X-Men under Cyclops's command.
Wolverine later reopened the official school as the Jean Grey School for Higher Learning, and the opening school roster expanded after AvX to include a large number of new students. The Xavier Institute for Mutant Education and Outreach also included a full student body, and additional students from the Akademos Habitat on Krakoa and post-Krakoa new mutants studying under the X-Men will also be included here, for categorization purposes if nothing else.
