Within school settings, there is both the opportunity and obligation to promote mental health for all children. The vision of effective School Mental Health (SMH) is one where a multidisciplinary group of professionals can offer services ranging from prevention to intervention, effectively removing barriers to learning and promoting mental wellbeing. Unfortunately, the reality of SMH has not yet caught up to the promise. Evidence-based practices are not implemented routinely, a comprehensive approach is lacking in most jurisdictions, and data-informed decision-making is virtually non-existent. The Centre for School Mental Health at Western University addresses those gaps between research, practice and policy. The Centre seeks to promote an expanded concept of SMH through innovative research partnerships, high quality training opportunities, and a commitment to knowledge mobilization.
