This Learning Brief provides a summary of five Youth Excel grantees’ Research-to-Change work in strengthening Menstrual Health and Hygiene (MHH) support for girls’ education in Malawi and Zambia. This activity provides small grants ($40,000–$50,000) to local, youth-led and youth-serving organizations. Youth Excel also provides tools and technical assistance to grantees so that they can conduct their own implementation research (testing and adapting MHH approaches) to strengthen their programming.
