Graduate Attributes
Graduate Attributes are the personal qualities, skills and understandings that University of
Southampton students have the opportunity to develop. They include but extend beyond subjectspecific knowledge of an academic discipline and its technical proficiencies. The Graduate Attributes
are achieved through the successful attainment of the learning outcomes of the programmes, and
successful engagement with the University’s co-curriculum e.g. the Graduate Passport.
A checklist for embedding the graduate attributes is available at:
