To capitalise on its vast portfolio of 41 projects, operating across 17 countries, the Girls’ Education Challenge (GEC) has compiled a wealth of project learning regarding key interventions related to girls’ education. The first in the series of Learning Briefs looks at the ways GEC projects are tackling school-related, gender-based violence. While these Learning Briefs are rooted in both quantitative and qualitative evidence, they are not research papers or evidence reports. Rather, they provide a synthesis of learning from GEC intervention designs and implementation approaches that have been paramount for supporting improvements in girls’ learning. The GEC projects take a holistic approach to improve the educational environment and conditions that support improved learning, participation, transition and sustainability outcomes.
