In the first half of the 20th century, the Congregation was also active in helping many young teachers, both religious and lay, already working in schools, to improve their skills and acquire higher diplomas and degrees. In 1916, a series of Pedagogical Conferences, partly subsidized by the Montreal Catholic School Commission, was inaugurated at the Mother House on Saturdays. The following year, Laval University recognized a three-year course of Saturday lectures and set out rules for a diploma program. Close to three hundred teachers registered and in 1920 seventy of them successfully completed two years of the program and received the Certificate of Pedagogical Competence. In 1921, four hundred and sixty teachers received the Certificate and eighty-nine completed the three-year program to gain a Superior Diploma. In response to this success, the Quebec Government passed a law concerning Pedagogical Institutes or Écoles Normales Supérieures.
As a result, the Institut Pédagogique opened in the autumn of 1926 in the new building also housing the Marguerite Bourgeoys College. Affiliated with the University of Montreal, it offered a Superior Diploma of Pedagogy for Elementary Schools and the degrees of Bachelor, Master and Doctor of Pedagogy. The Normal School of Music, an integral part of the Institute, and also affiliated with the University of Montreal opened in 1926, offering certificate and degree programs, including that of a doctorate in the teaching of music.
