Do honours students always require ethics approval for their thesis?

Yes. For educational purposes, all honours students must submit an ethics application for their thesis, including for anonymous archival research. In addition, honours students must include a copy of their ethics clearance certificate, which includes the study reference number, when they submit their thesis. Honours students whose theses are part of an approved program of research for the current academic year only need to submit a copy of the ethics approval certificate with their thesis and need not apply for separate ethics approval for their thesis.
