SGDSB Secondary Schools

The Superior-Greenstone District School Board incorporates a number of secondary schools within our communities. We are highly committed to providing students with a superior level of education, that not only prepares them for post-secondary studies, but also allows them to develop in their understanding of themselves and the world around them.

For further information on our local high schools, please select from the listing of school names to the left. You will be redirected to contact information for each school.
