The study examines the perceptions of 104 mid-and senior-level student affairs administrators of positions, responsibilities, competencies, and theories important for professional practice for new student affairs professionals. In regard to competencies, the results of this study provide important information about preprofessional abilities that are integral to professional practice, and participants also identified several competencies not identified in prior research that may be important to positions involving high contact with students. These results, then, provide vital information for curriculum development in graduate preparation programs and for professional development training for new professionals. (Contains 4 tables.)
