This policy brief highlights five evidence-based strategies identified by ICRW to delay or prevent child marriage: 1) Empower girls with information, skills and support networks; 2) Provide economic support and incentives to girls and their families; 3) Educate and rally parents and community members; 4) Enhance girls’ access to a high-quality education; and 5) Encourage supportive laws and policies. In order for the next generation of development programs to make ending child marriage a priority, policymakers must pay attention to these strategies while continuing to test innovative approaches and evaluation techniques.
