Early on, Galinda notes that Crage Hall "wasn't one of the better colleges - they were still closed to female students. But it was Shiz University." Madame Morrible is the headmistress of Crage Hall, attended by Grommetik, a Tik-Tok creature that does her bidding. The university is attended by many of the main characters of the story, including Elphaba, Galinda, Fiyero, Nessarose , and Boq. A Goat Doctor Dillamond is a prominent science instructor and Animal activist, whom Elphaba briefly assists in the lab before his throat is slit under rather dubious circumstances. In time, the authoritarianism of the Wizard restricts the curriculum and teachers to such a degree that Elphaba drops out.
In the musical, Shiz is a (presumably) co-educational university of which Madame Morrible is the headmistress, and where all of the main characters study. It is somewhat cliquish, as Elphaba is ostracized for her looks and ways while Galinda is easily the most popular girl in school. No two students outfits are alike, except for the colors of dark blue and white. This is to show that they may think they are all individuals but are actually all the same.
The University's "Ozma-Mater" is Dear Old Shiz, sung in the musical by Galinda and the Students.
Attended by Elphaba, Glinda, Nessarose and Glinda's Friends. It is an all-girls school and, according to Glinda, not one of the better colleges. It appears to be a general studies college. Madame Morrible is the Headmistress.
Each girl who attends Crage Hall is required to have an Ama, that is, an older female chaperon who will watch over them and attend to their needs. The Amas apparently work amongst themselves to sort out who should room with who, and so function as an assignment system. Having an Ama seems to be a sign of social status, as it's likely a poorer student would not be able to afford one. Students without an Ama are assigned to a group dormitory, known as the Pink Dormitory, and are usually considered social outcasts
Attended by Boq and Avaric. According to Glinda, It is an agricultural school. Assumingly, Boq goes there to improve his farming skills, which he will need later in life. It apparently has the most extensive library on campus. It is a co-eduational school. The Crage Hall dormitory is across the alley and over a stable.
Attended by Tibbett and Crope. It appears to be a theatrical school and apparently has an extensive library. It is implied that the seemingly all-male students are gay or bisexual.
Attended by Fiyero. It may be a political school, as Glinda mentioned there is one. It is the least explored in the novel.
