title: Practice in computer-based testing improves scores on the National Certification Examination for Nurse Anesthetists.
abstract: This retrospective study examined whether practice in computer-based tests (CBTs) in student registered nurse anesthetists improved scores on the National Certification Examination (NCE). A group of students with extensive practice in CBTs was compared with a group of students whose tests were administered primarily on paper. Groups were matched on age, grade point average (GPA), and gender (n = 73 each). Higher GPA was associated with higher NCE scores overall. Adjusted for GPA (with analysis of covariance), the mean NCE proficiency score (phi) in the CBT group was 2.68 (95% confidence interval, 2.54-2.82), which was higher than the mean score in the paper-based group of 2.36 (95% confidence interval, 2.22-2.50), with an effect size of 0.52. When subgroups were examined, CBT practice improved NCE scores only in those students with graduate GPA less than or equal to 3.50, with an effect size of 1.1. It was concluded that, controlling for GPA, student registered nurse anesthetists at a university with greater exposure to CBTs had higher scores on the NCE than a comparison group with less practice in CBTs. This difference was significant only in students with GPA of 3.50 or less, consistent with a beneficial effect of practice in CBTs.
