This study investigated behavioural tendencies of Library and Information Science undergraduates towards CBE in Nigeria. Five objectives and two hypotheses were formulated to guide the study. Descriptive survey research design was adopted using the online survey monkey app to collect data/responses from library and information science (LIS) undergraduates. The population of the study comprised all LIS students in Nnamdi Azikiwe University, Ambrose Alli University and Benson Idahosa University. The sampling technique used for the study was total enumeration sampling technique (169) as the whole responses were used for the analysis using charts and tables for easy appreciation and comprehension. Also two null hypotheses were tested at alpha level 0.05 using Analysis of Variance (ANOVA). It was found out that: Most of the respondents studied prefer Computer based examination to Paper based examination and both concurrently, respondents have positive perception towards Computer Based Examinations (CBE), majority of the students in the three universities have quite a positive attitude towards Computer Based Examinations (CBE), majority of the respondents agreed to the problems facing the full adoption and use of CBE in their institutions, there is a statistically significant difference between the means of the different rates of perception of the undergraduates towards CBE in federal, state and private universities variable and others. Obviously, students of this generation wish to continue learning using modern technological devices. To this end, government and school administrators should endeavour to encourage the use of CBE/CBT and other ICT facilities in order to fast track teaching and learning among students. This will not only help students but also help teachers in easily realizing objectives.
