This study investigated the impact of technology problems on students’ perceptions of computerised examination technology and procedures. Measures included the suitability of the assessment task to computerisation, ease of use of the e-examination (e-exam) software, technical reliability, and the perceived security of the approach. A case study was conducted around the introduction of computerised tests into a second-year undergraduate biochemistry course. A series of three e-exam trial events were conducted at an Australian university in 2019 using laboratory bench computers. All students in the course were required to undertake the series of computerised examinations. Data were gathered using pre-post surveys of students’ perceptions (n = 215) that included qualitative comments and Likert items. This study focuses on the impact of a server slowdown at one of the sessions upon participants’ responses to Likert survey items that included their recommendation of the e-exam approach to peers.
