MHPSS in Action was a three-year research project that provided an in-depth analysis of the Norwegian Refugee Council’s Better Learning Programme in Colombia and Kenya, and Amal Alliance’s Colours of Kindness initiative in Greece. At the end of 2022, 40% of the nearly 110 million persons forcibly displaced globally were children under the age of 18. Displaced children face acute and chronic adversities that significantly threaten their mental health and psychosocial wellbeing. The urgent needs of children in humanitarian crises underpin various policies and programmatic approaches that include increasing attention to both mental health and psychosocial support (MHPSS) services broadly and in education approaches specifically. MHPSS in education in emergencies (EiE), including social-emotional learning (SEL), has been identified as an important pathway to address both children’s mental health and psychosocial needs and to improve learning outcomes.
