The aim of the 4-phase research was to answer the following question: “What are some feasible options for online proctoring systems (OPSs) for offering online exams for NUS?” This paper is based on the last phase of this 4-phase study conducted at NUS to evaluate the feasibility of two proctoring systems, Integrity Advocate and Proctorio, for online exams, particularly during lockdown. Specifically, the objectives were to i) trial and evaluate the suitability of each OPS as well as the type of exam mode (two options: in the laboratory or from home) using a diffusion of innovation framework and, from the evaluation, recommend a suitable OPS for NUS. Both between-subjects and within-subjects analyses revealed highly positive responses for both OPS and exam mode across the 5 variables of the diffusion of innovation model of relative advantage, compatibility, ease of use, observability, and trialability. Most of the findings did not show any differences by OPS type, exam mode, or gender, as most responses across the 5 variables of diffusion of innovation were highly positive and very similar, indicating positive and high rates of adoption of the two OPS. An in-depth investigation into the features of the two OPS also revealed that Proctorio had a wider scope of features than Integrity Advocate.
