This study was a qualitative examination of the stress responses and coping strategies of 21 teachers (12 women & 9 men), and school response mechanisms following a critical incident involving the death of a student or colleague. In order to explore the possibility that deaths of a relatively common nature can evoke high stress and grief responses, exceptional or large scale events, or those generating widespread public or media attention, were excluded. Findings showed that the impact on participants was high, and included cognitive, emotional, functional and physiological responses. Six discrete wellness factors, considered to contribute to effective coping, were identified: emotional and practical support, active involvement, responding according to individual need, access to information, readiness, and leadership. A salutogenic (wellness) approach to critical incident management was considered to provide a comprehensive and effective model for supporting individual teachers and the school in mobilising coping and restorative strategies and mechanisms. Implications for critical incident management in schools, and directions for further study, are discussed.
