Validity in Computer-Based Testing: a Literature Review of Comparability Issues and Examinee Perspectives (original) (raw)

These past years have seen the growing popularity of the Computer-Based Tests (CBTs) in various disciplines, for various purposes, although the Paper-and Pencil Based Tests (P&Ps) are still in use. However, many question whether the use of CBTs outperforms the effectiveness of the P&Ps or if the CBTs can become a valid measuring tool compared to the PBTs. This paper tries to present the comparison on both the CBTs and the P&Ps and their respective examinee perspectives in order to figure out if doubts should arise to the emergence of the CBTs over the classic P&Ps. Findings show that the CBTs are advantageous in that they are both efficient (reducing testing time) and effective (maintaining the test reliability) over the P&P versions. Nevertheless, the CBTs still need to have their variables well-designed (e.g., study design, computer algorithm) in order for the scores to be comparable to those in the P&P tests since the score equivalence is one of the validity evidences needed in a CBT.
