This thesis explores the relationship between education, governance, and poverty reduction specifically in rural Tanzania, focusing on the role of Official Development Assistance (ODA). It argues that the main cause of persistent rural poverty in Tanzania is the low levels of education rather than governance issues. The analysis specifically examines South Korea's ODA in the education sector and governance in Tanzania to understand how donor support, like that from KOICA, can contribute to alleviating poverty. The study utilizes descriptive and analytical methods, drawing on prior research to demonstrate the impact of education on the effectiveness of ODA and development initiatives. The findings emphasize the crucial role of investing in education for poverty reduction in rural Tanzania. The research highlights the need for increased investment in education by organizations like KOICA, specifically in areas such as education infrastructure, teacher training, curriculum development, vocational education, civic education, environmental education, and the establishment of Information and Technology centers in impoverished communities. By rapidly investing in rural education in Tanzania, South Korea's ODA can have a significant impact on poverty alleviation. This study contributes to ongoing efforts to promote sustainable rural development in Tanzania by underscoring the importance of education as a key driver of development.
