Does the OSCE, as designed, add to the validity of Pharmacy Examining Board of Canada certification?
6. Assessment of knowledge through written tests and assessment of skills through performance assessment correlate significantly, but modestly (r=0.52). This suggests these different testing methods complement (but do not replace) one another, and are useful for measuring different domains of competency. In essence, candidates who may pass one component (ie, the written examination) may not necessarily pass another component (eg, the OSCE), and vice versa, suggesting a more robust assessment system. 7. Overall, reliability (Crohnbach’s alpha) of 0.84 was high for a 15-station OSCE with one pharmacist-assessor using holistic scoring, making this instrument an appropriate addition to the model for entry-to-practice certification of pharmacists. 8. When scored using holistic scales by 15 different pharmacist assessors (one per station), the 15-station Pharmacy Examining Board of Canada OSCE is a suitable tool for discerning competency among entry-level pharmacists. These findings from the
