This study explored the causal relationships among readiness for practice, transition shock, and turnover intention of new graduate nurses. The findings suggest that higher readiness for practice decreases transition shock and influences the intention to leave. To retain a valuable nursing workforce, nursing schools should strive to create a supportive learning environment that prepares students with a high level of readiness for practice. Additionally, hospitals' nursing managers and administrators should implement a structured adaptation program for new graduate nurses to facilitate a smooth transition into the profession.
