This study examined the perspectives of an expert panel of 31 business education university supervisors from the U.S. and Canada using a modified Delphi approach regarding the areas in which mentor teachers are typically most and least prepared. Findings indicated business education mentor teachers are most prepared in the areas of classroom management, teaching-related administrative duties, and establishing rapport. However, the expert panel did not reach consensus on the areas in which mentor teachers are oftentimes least prepared. The majority of the university supervisors believed business teacher preparation programs could provide mentor teachers with professional development on mentoring and expectations prior to the internship.
