The COVID-19 pandemic motivated higher education institutions to adopt the use of e-proctoring software as a means to maintain academic integrity. This study explores the tension between student privacy and academic integrity from instructors' perspective. Through semi-structured qualitative interviews with 19 university instructors, our findings delineate the competing factors influencing instructors' adoption or avoidance of e-proctored assessments: academic integrity, the online remote format, logistical considerations such as class size, departmental policies, and privacy considerations. We analysed instructors' specific privacy attitudes towards e-proctoring, and perspectives regarding student privacy and institutional data protection practices.Lastly, we evaluated instructors' appraisals on the efficacy of e-proctoring software.We found that most instructors deprioritized privacy considerations when deciding whether to adopt e-proctoring, but viewed academic integrity as the topmost inviolable priority. Overall, we provide insight into the complexities of managing privacy and competing priorities from the instructors' perspective, and offer recommendations for instructors and institutions.
