St. Michael's Regional High, opened in 1986 under the jurisdiction of the former Roman Catholic School Board to serve the communities of Bell Island. It was built to replace the ageing St. Edward's High School. There were two high schools on Bell Island when it opened.  St. Boniface was operated under the jurisdiction of the Avalon Consolidated School Board. Both high schools were grades 7 - Level III.

Following amalgamation of the two school boards in the late 1990's, the school system on Bell Island was restructured. St. Boniface closed and St. Michael's became the only high school serving students in grades 9 - Level III. St. Augustine's became a K- 3 school and Immaculate Conception School went from a K-6 school to a grades 4 - 8 school.

In 2004, Immaculate Conception school was closed and St. Michael's became a grade 7 - Level III school.

St. Michael’s Regional High has a student population of approximately 130 students and a teaching staff of 13. We offer the standard provincial curriculum and a variety of extra curricular activities.
