Current Status



Gender and Adolescence: Global Evidence (GAGE) an exciting, longitudinal research initiative working in the Global South, aims to strengthen the evidence base on adolescent girls – as individuals and as future women– to maximise their capabilities and shape their own futures. GAGE research focused on what policies and programmes work, where and why. It identified the medium- and long-term impacts of interventions for girls, and ascertained how best to time and sequence those interventions. The consortium, including EDI Global as a consortium partner, is producing a global body of evidence, based on data gathered through innovative approaches over eight years (with a potential five-year extension) which will go beyond current frameworks to advance the well being of adolescent girls. An in-depth, mixed-methods programme of longitudinal research was undertaken in four focal countries in Africa and Asia, balancing a mix of ‘gold standard’ impact evaluation approaches with innovative implementation and action research. 

EDI provided expertise in the development and configuration of the data collection instruments and fieldwork protocols. EDI Global led training sessions in-country and helped to guide the consortium through the data collection phases using the survey software surveybe. The EDI Global data centre was responsible for data processing and data cleaning. Our team liaise closely with local country partners to identify and resolve data queries in near-time. Finally EDI Global provided the consortium partners with the final dataset by country for analysis.
