This study examined work engagement and its role in mediating the relationship between organizational support of evidence-based practice (integrating research evidence to inform professional practice) and educational growth and perceived professional expertise. Participants included 78 currently employed counselors, graduates of a master’s program in mental health counseling located in an urban northeastern university. Results revealed that work engagement significantly mediates the relationship between organizational support of evidence-based practice and educational growth and perceived professional expertise. Implications for counseling practice and recommendations for future research are discussed.
