Supporting students returning to school after a mental health crisis often involves more training than many school staff members receive. With the increase in youth mental health diagnoses, there has also been an increase in the number of youth requiring psychiatric emergency department visits and hospitalizations. As such, this study employed a basic qualitative design to gather the perspectives of school staff who support students' mental health about their experiences and training needs related to supporting youth returning to school after psychiatric hospitalization. Semi-structured interviews were conducted with 10 school mental health professionals or administrators. Thematic analysis was used to analyze the data. Three themes were identified: (1) most participants received minimal formal training in graduate school on hospital-to-school transition, (2) most participants learned about hospital-to-school transition on the job, and (3) participants made recommendations and identified specific training needs. Implications for training are discussed including a need for variety (e.g., some practitioners need basic training while others need more advanced training) and different format preferences (in-person may be preferred but online asynchronous is more convenient).
