Concerns about teacher burnout, compassion fatigue, and retaining early career professionals have prompted teacher education programs to seek out ways to promote mental and emotional health during pre-service teacher training. This two-year, educational design study explored pre-service teachers' experiences with the implementation of two school-based mental health interventions: the intentional introduction of self-care planning during field experience practicums, and the promotion of 'streaking', a health promotion event, to encourage pre-service teachers to implement a daily individual mental health intervention. Data were collected at several different points over a two-year period through surveys and individual interviews. The data analysis indicated that this two-tiered approach holds promise as a health promotion activity, however other intentional and educational actions were needed to ensure that pre-service teachers had the resources and tools required to support their mental and emotional health during their practicum courses. A further finding suggested that the term 'self-care' was widely misunderstood by study participants and work is needed to help pre-service teachers understand the importance of self-care during their practicum as a prevention strategy for well-being once they begin their teaching career.
