Rater reliability is about consistency across evaluators when scoring a performance. In physical therapy performance assessments, different clinicians may rate the same task differently because of subjective judgments. To improve reliability, use a rubric with explicit criteria and clear score anchors so everyone applies the same standards. Provide structured rater training to familiarize all evaluators with the rubric and expectations. Use exemplars that show what each scoring level looks like, and run calibration sessions where raters score the same performances and discuss any discrepancies until scoring decisions align. Periodic retraining and ongoing feedback help maintain consistency over time. If feasible, involve multiple raters and use their scores in combination to reduce individual bias, and ensure standardized assessment conditions so differences reflect performance rather than context.
