This research brief provides a snapshot of Girls’ Access To Education (GATE), a non-formal education programme that aims to bring the most marginalized adolescent girls in Nepal into school. The nine-month programme provides out-of-school girls with the basic literacy, numeracy and life skills they need to enter and learn in formal schooling. The analysis draws on GATE monitoring data for 2018/19, covering 7,394 GATE beneficiaries in five districts of Nepal, and is combined with qualitative evidence including case studies and focus group discussions with former GATE participants conducted in 2019. The mixed-methods analysis finds that the GATE programme has been highly effective, with 95% completion of the programme by enrolled girls and 89% of girls making the successful transition to formal school. Moreover, GATE graduates enrolled in Grades 3 to 5 in formal schools outperformed non-GATE girls enrolled in the same grades, even though GATE girls overwhelmingly had no prior formal school experience. Qualitative evidence reveals that poverty, caring responsibilities and parents’ traditional views may be important factors in explaining why GATE girls had never previously attended school. Despite this, GATE beneficiaries who were interviewed maintain a positive outlook on the future and have clear career goals. One of the recommendations stemming from this brief is to explore the feasibility of expanding GATE approaches to target out-of-school children in other contexts, as GATE has been a cost-effective solution in the context of Nepal.
