Building on three interpretive conceptual frameworks –Education in Emergencies (EiE), Education as a Humanitarian Response (EHR), and the human rights-based approach to education–, this paper analyses the experiences, challenges, and opportunities concerning access to compulsory education for Venezuelan migrant and refugee children in Barranquilla. By shedding light on the educational humanitarian response in Barranquilla, I draw lessons on access to education for humanitarian responses in large-scale migration settings. This exploratory research applies grounded theory to analyse 35 semi-structured interviews with 45 individuals and observation conducted in Barranquilla. I identify six challenges and four opportunities in Barranquilla, and four implications for humanitarian responses concerning access to education for migrant and refugee children. Thereby, this study contributes to a better understanding of factors that impact access to compulsory schooling with a special focus on the various coordination agencies (governmental institutions, humanitarian actors) and the institutional (public schools, incl. administration and teachers) as well as the individual level (migrants and refugees).
