Abstract: This paper explores the relationships within teaching, learning and practice development in critical care nursing and questions the popular assumption that 'post graduate (Master's level) education fits all'. The need for critical care nurses to apply advanced knowledge and technical skills to complex and dynamic practice situations necessitates the development of critical thinking and a problem-solving approach to clinical practice that can be fostered through education and experience. Discussion focuses on the successful development and implementation of graduate level education for critical care nurses in the South Island of New Zealand and how this development is challenging existing approaches to the provision and evaluation of formal critical care education in New Zealand.
