This policy brief outlines how the NGO CARE International has developed programmes to engage men and boys for over 15 years with the aim of achieving gender equality. It draws on evidence from the curriculum-based approach developed in the Balkans, and a three-year pilot programme in the Great Lakes Region of Africa. It concludes with recommendations focusing on the role that donors, governments, civil society and education specialists can play to ensure that successes can be replicated and scaled up.
