Government guidance in 2008 endorsed the "Targeting Mental Health in Schools" (TaMHS) agenda, which sets out to promote mental health in schools through the delivery of universal and targeted interventions. This paper initially defines mental health and outlines the TaMHS initiative. It then offers empirical findings from four focus groups with schools who took part in the TaMHS initiative in one local authority. Socio-cultural activity theory is used as an analytic framework to explore perceived outcomes of TaMHS, as well as providing insight into the processes of TaMHS implementation. Data were analysed using thematic analysis. Findings are consistent with existing literature and suggest positive outcomes for children, staff and the whole-school system. Implications for the role of educational psychologists in continuing to promote mental health in schools and considerations for effective implementation are discussed.
