Pakistan is the 6th most populous country of the world with population over 188 million; Almost 35% of population is under the age of 14. Country cannot afford to ignore mental health of this large group. School experiences are important for children emotional, psychological and social development World Health Organization (WHO) also identifies promotion of emotional health and well- being as a core feature of their Health promoting school initiative. Schools can play an important role in promoting positive mental health, reducing stigma, raising awareness among teachers, parents and children about mental health issues as well as identifying and supporting youth experiencing mental health difficulties. Furthermore, mental health initiatives in schools help teachers to feel less stressed and be more satisfied with their role and save costs. Educational interventions involving teachers have shown significant improvement in teachers knowledge and attitudes regarding mental health & better accuracy of teacher identification of children and adolescents with mental health problems. Although importance of schools for mental health promotion and early identification for mental health problems has been evident for quite some time, it is almost nonexistent in developing countries including Pakistan with only a handful of studies focusing one aspect of health promoting school or on one disorder. World Health Organization, Eastern Mediterranean Region (WHO-EMRO) has developed a concise and practical manual of school mental health in December 2014.This manual is primarily intended for all stakeholders involved in the educational process including teachers. It aims for helping educators to take practical steps that can be implemented at low costs in school settings.
