This paper documents the impact of a cash transfer programme – an initiative of the Government of Lebanon, the United Nations Children’s Fund (UNICEF) and the World Food Programme (WFP), widely known as the No Lost Generation Programme (NLG) and, locally, as Min Ila (‘from to’) – on the school participation of displaced Syrian children in Lebanon. The programme provides cash to children who are enrolled in the afternoon shift of a public primary school. It was designed to cover the cost of commuting to school and to compensate households for income forgone if children attend school instead of working, two critical barriers to child school participation. We rely on a geographical regression discontinuity design comparing children living in two pilot governorates with children in two neighbouring governorates to identify the impact of the programme halfway in the first year of operation (the 2016/17 school year). We find limited programme effects on school enrolment, but substantive impacts on school attendance among enrolled children, which increased by 0.5 days to 0.7 days per week, an improvement of about 20 per cent over the control group. School enrolment among Syrian children rose rapidly across all of Lebanon’s governorates during the period of the evaluation, resulting in supply side capacity constraints that appear to have dampened positive impacts on enrolment.
