Role ambiguity in professional school counseling is an ongoing concern despite recent advances with comprehensive school counseling models. The study outlined in this article examined role diffusion as a possible factor contributing to ongoing role ambiguity in school counseling. Participants included 109 graduate students enrolled in a CACREP-accredited counseling program at a large southwestern university. Findings suggest that providing direct counseling services is the most unique and least diffused role for today's school counselors. The authors also review implications for professional school counselors and recommendations for future research.
