This study explores Hong Kong higher education students' perceptions of E-assessment systems, focusing on factors shaping acceptance of E-examinations over traditional formats. Quantitative analysis of 107 respondents reveals significant positive correlations between diverse pre-exam guidance (e.g., tutorials) and key system features (e.g., usability, user friendly), and between these features and effective E-examination feedback (e.g., instants feedback) and identity monitoring techniques (e.g., webcam surveillance). E-examinations' advantages also correlate with enhanced monitoring identity. Prior experience boosts guidance value. These findings urge institutions to refine E-assessment with robust guidance, intuitive design, and reliable monitoring to enhance engagement, integrity, and satisfaction. Limited sample diversity suggests broader demographic studies. Results inform E-assessment optimization across contexts.
