Assessments are important to academic institutions because they help in evaluating students' knowledge. The conduct of assessments nowadays has been influenced by the continuous evolution of information technology. Hence, academic institutions now use computers for assessments, often known as Computer-Based Assessments (CBAs), in tandem with Paper-Based Assessments (PBAs). The literature, however, shows that the use of CBAs has received controversial reactions, and also shows that students face challenges when undertaking CBAs. This study was conducted to understand the perceptions of students and the challenges they face when undertaking CBAs. The study employed a descriptive research approach and data was collected through questionnaires. A total of 210 questionnaires were distributed to students. Findings show that students find it easy to undertake CBA and hence prefer it to PBA. However, the findings also show that students experience challenges that include Internet connectivity and mode of presentation of items, when undertaking CBA.
