The Master Class was developed as an additional educational innovation designed to promote learning about mental health and illness and mental health nursing as a career option to 2nd-year undergraduate nursing students. A number of students had approached the mental health nursing academics expressing two polar views on mental health. They either expressed extreme interest in mental health nursing or significant distress and concern related to studying the core 2nd-year subject. It was considered that the Master Class could potentially provide students with additional support. It was thought the Master Class may either consolidate their interest in mental health or relieve their stress. This article presents the findings of a pre- and postevaluation which was employed to explore the effectiveness of the 5-day intensive mental health Master Class programme on student's mental health learning and their understanding of the role of a mental health nurse. The findings highlighted that prior to participating in the Master Class, there was a significant sense of uncertainty associated with perceived levels of competence required within the profession of mental health nursing. This was coupled with students expressing they wanted to disengage with the profession even before they had commenced any theory or clinical experience. The post-Master Class findings illustrated a significant improvement in students desire to consider mental health nursing.
