Context: Teaching, scholarship, and service are required of all faculty in order to earn tenure. Faculty members hired directly from doctoral programs may not be adequately prepared to face the responsibilities of a full-time position in the professoriate. Objective: To explore what mechanisms as part of doctoral education influenced the perceptions of junior faculty development while transitioning postgraduation. Design: Qualitative phenomenological study. Setting: Fourteen higher education institutions. Patients or Other Participants: Sixteen junior faculty (7 male, 9 female, age = 32 ± 3.5 years) representing 7 National Athletic Trainers' Association districts participated. At the time of the interview, participants were within their first 3 years of a full-time faculty position. All participants earned doctorates from residential programs and had an assistantship position. Main Outcome Measure(s): All participants completed a semistructured telephone interview. The interview guide was focused on the experiences of junior faculty within their first 3 years in a tenure-track position. Questions were grounded within the literature and purpose of the study. We analyzed the interviews through a psychosocial developmental lens using a general inductive approach. Results: Two themes of doctoral preparation emerged that influenced the perceptions of junior faculty transitioning into a faculty role: "breadth and depth of the doctoral assistantship" and "doctoral coursework related to academia." Doctoral assistantships with breadth and depth helped participants develop competence, while doctoral coursework related to academia provided content expertise. Conclusions: Doctoral education is the platform for transition into academia. Our findings suggest that doctoral program assistantships that provided both breadth and depth of experience facilitated transition. Coursework related to academia influenced perceptions of transition into the faculty role by exposing participants to pedagogy and higher education infrastructure.
