Gender and Adolescence: Global Evidence (GAGE) is a nine-year (2015-2024) mixed methods longitudinal research and evaluation programme funded by UK Aid from the UK government. It will generate and share evidence on good-practice programmes and policies to help adolescent girls in the Global South reach their full potential. The IRCKHF is conducting in-depth interviews and focus group discussions with adolescents and their families as well as key informant interviews to understand the effectiveness and impact of services provided to adolescents (10-19) across the country.
