Increasing rates of mental health difficulties for young people in the UK are often described, though seldom from young people's perspective or viewpoint. The Schools NorthEast Healthy MindED Commission works towards supporting schools to understand and mitigate the factors affecting young people's mental health, and through doing so enable better resilience. This research extends from the work of the commission. Utilising the World Health Organisation mental health definition, we supported schools to have conversations with young people about the factors that affect their mental health. Staff from regional schools were trained and supported to carry out focus group discussions and complete initial data analysis. Meta-analyses of findings were carried out to identify illuminative themes. Findings were fed back to establish face validity and so allow further action planning -- not reported here. Themes are considered against established theory and the wider literature. In addition to illustrating the usefulness of listening to young people in order to understand mental health in school contexts, crosscutting themes of relationships, agency, and rest and recovery were concluded as key to enabling mental health within school contexts.
