The aim of the MM+ initiative is to build the capacity of secondary schools to ensure optimal mental health outcomes for all students at risk. This is achieved in a number of ways, including early identification, implementation of preventative and early interventions, refining processes, policies and strategies, and encouraging the development of community partnerships. This article will focus on the latter of these strategies: how schools can further develop partnerships with their local community in order to build their capacity to support student mental health. Research indicates that it is beneficial for schools to work with individuals and agencies in the community, as it can result in more resources and services for students than are possible when schools work alone. This article will outline research in the area of building community partnerships including an examination of the types of partnerships, that can be formed and the issues to be considered. In addition, the article will provide a practical discussion of what the MindMatters Plus demonstration schools have learned as a result of their experience in building community relationships.
