Objective: To evaluate the Transition to Practice in Aged Care (T2PAC) internship of clinical placements that enable third-year nursing students transition to Registered Nurses (RNs) in aged care. Background: Aged care is complex care but nursing programs include minimal gerontology content and most aged care placements occur in first year. This leaves a critical gap in students’ preparedness and clarity about the RN role in aged care. T2PAC was designed to address this gap by integrating three strategies: RN preceptorship, seminars on complex aged care topics, and student led case studies. Study design and methods: A two-stage multi methods study was undertaken within one aged care organisation: Stage 1: interviews with stakeholders and seminar evaluation surveys and Stage 2: online post-placement short-answer questionnaires completed by nursing students. Results: Thirty students completed T2PAC and 25 (83%) participated in data collection. Students reported increased confidence, knowledge, and clinical skills. Nine stakeholders undertook interviews and reported that the students became aged care graduate workforce ready. Seminar evaluation surveys revealed that they were highly valued, and the short-answer questionnaire found that the case studies enabled contextualised learning in practice. The main challenges were related to preceptor allocation and preparedness. Conclusion: T2PAC’s effectively supported students’ transition to aged care. This study demonstrated that when final year aged care placements become a standard curriculum feature and there is investment in RN preceptorship preparation students successfully transition into aged care. T2PAC provides a model to fast track the creation of a specialist gerontological nursing workforce in aged care.
