Abstract: Sustainable financing is fundamental to the effectiveness of Early Childhood Development (ECD) programmes in humanitarian contexts, yet limited empirical evidence exists on how available funding supports service delivery in refugee settlements. This study examined the extent to which financial resources support Early Childhood Development programs in Kyangwali Refugee Settlement, Uganda, guided by Bronfenbrenner’s ecological systems perspective. A descriptive cross-sectional design employing mixed methods was used to collect data from 236 stakeholders, including Centre Management Committee members, teachers, parents, settlement officials, and partner organizations. Quantitative data were analyzed using descriptive statistics, while qualitative data were subjected to thematic analysis. Findings revealed that available funding was found to be largely donor-driven, project-based, and insufficient to meet the expanding needs of ECD centres, particularly in relation to teaching materials, caregiver support, and inclusive services. Despite generally positive perceptions of funding adequacy, 2.5% of the respondents indicated that available financial resources were insufficient for teaching and learning materials, reflecting persistent resource gaps across ECD centres. The study concludes that while financial investments contribute meaningfully to ECD programme implementation in refugee contexts, their impact is constrained by structural funding limitations and weak integration between humanitarian and development financing. The study recommends the adoption of predictable, long-term, and integrated financing mechanisms aligned with national ECD frameworks to enhance sustainability and equitable access to quality early childhood services in refugee settings.
