Within the last decade, there has been a significant shift in the field of social work toward competency-based education. This article details the use of the Objective Structured Clinical Examination (OSCE) Adapted for Social Work Performance Rating Scale. We used the measure to evaluate specific practice competencies among students (n = 33) participating in a professional workforce development program, funded by the Health Resources Services Administration Behavioral Health Workforce Education and Training for Professionals. We report on students' performance and their views of the OSCE as an assessment measure and learning experience, and on the interrater reliability and consistency of the OSCE. Results can be used by other social work programs to inform the use of OSCEs to facilitate competency-based assessment.
