The private college network regroups diverse and renowed higher education institutions. Le Petit Séminaire de Québec (1668) and the Séminaire de Sherbrooke (1875) are historical pillars. Some institutions such as the Collège André-Grasset (1927), Collège Jean-de-Brébeuf (1928) and Marianopolis College (1943) were founded by religious communities wishing to ensure the development of classical colleges in Quebec, while others were created in order to offer specialized training programs . This is the case of the Conservatoire Lassalle (1908) in communication, École de musique Vincent-D’Indy (1932) in music, Collège O’Sullivan de Montréal (1916), College Bart (1917), Collège Ellis (1930) and Collège O’Sullivan de Québec (1942) in secretarial studies as well as the Teccart Institute (1945) in electronics.
In 1968, colleges have come together to form the Association des collèges du Québec which in 1993 became the Association des collèges privés du Québec.
