Gender equality in and through education is critical to the achievement of the 2030 Agenda for Sustainable Development, as many experts have observed, and investing in this area yields substantial public and private returns. It is a key driver of economic and social development and leads to gains in health, nutrition and many other areas. Support to advancing gender equality is offered to countries primarily through activities that support the Global Partnership for Education's (GPE's) three country-level strategic objectives: (1) sector planning and policy implementation; (2) mutual accountability; and (3) effective financing. This policy brief presents: (1) Progress toward gender equality in GPE Countries; (2) GPE support to gender equality; (3) Advancing gender equality in GPE countries; and (4) The next steps to take for gender equality in GPE countries.
