The current paper explores confidentiality between professors and students, as well as psychologists and clients, while bringing particular attention to professors teaching psychology and also holding registration as psychologists. Confidentiality is a cornerstone of applied psychology, yet confidentiality may have different meanings in the day to day realities of professors of psychology compared with registered psychologists. In addition, student perceptions and expectations of confidentiality between themselves and psychology professors further complicate confidentiality expectations in the post-secondary context. Implications for practice and future research are discussed.
