Performance-based assessment during clinical placement: cross-sectional investigation of a training workshop for practice educators

Performance-based assessment evaluates a health professional student's performance as they integrate their knowledge and skills into clinical practice. Performance-based assessment grades, however, are reported to be highly variable due to the complexity of decision-making in the clinical environment. The aim of this study was to evaluate the impact of a training workshop based on frame-of-reference principles on grading of student performance by physiotherapy practice educators. This was a prospective cross-sectional study which used a single group pre-test, post-test design. Fifty-three practice educators rated two video vignettes depicting a poor and very good student performance, using a subsection of a physiotherapy performance-based assessment tool before and after training. Overall, results showed that participants amended their scores on approximately half of all scoring occasions following training, with the majority decreasing the scores awarded. This impacted positively on scoring for the poor performance video, bringing scores more in line with the true score. This study provides evidence of the benefit of a training workshop to influence decision-making in performance-based assessment as part of a wider education program for practice educators.
