This qualitative case study describes the experiences of young refugee children and their families accessing early childhood development (ECD) services in Bangladesh in late 2019. The study team collected data through key informant interviews with representatives of the Bangladesh government, national non-governmental organizations, humanitarian agencies and service providers. Focus group discussions were held with refugee families living in both older and newer (post-2017 influx) camps near Cox's Bazar. The study team supplemented key informant interviews and focus group with policy document review. Analysis is presented along the lines of policy and practice, with a focus on the respective roles of the government and international agencies in delivering ECD services to refugee families.
