Doctoral submissions are always designated as a thesis.
Updated: the term 'dissertation' is not officially used for SFU doctoral submissions, per Graduate General Regulation 1.7.5 and the Office of the Graduate Studies and Postdoctoral Fellows. (3.14.2017)
A master’s degree submission is classified as a thesis, project, or extended essays according to Graduate General Regulation 1.7.2.
Students are responsible for entering their graduating course number in the Thesis Registration System, and for entering the correct submission type on the title page of the document. Consult your department's graduate program assistant to check the course number and submission type.
