ABSTRACT The aim of this study was to investigate the impact of ADP in socio-economic development of Rwanda. A case study of Bugesera District ADP was chosen as the area of study. The general objective of the study was to assess the effects of ADPs in socio-economic development in Rwanda specifically for Bugesera ADP. The specific objectives were to examine the development system in Bugesera; to analyze the impact of ADPs in Socio economic Development in Bugesera and to examine the extent of collaboration between ADP, local government and other partners. The research design used was a case study method where Bugesera ADP was considered as the unit of analysis. The targeted population comprised of the World Vision Rwanda Management Team, Bugesera ADP Management Committee/local Leaders and Bugesera ADP Local staff. Sources of data included both primary and secondary. Data was collected using questionnaires and self administered interview methods. The study used scientific procedures to obtain a sample of 45 respondents who were selected using simple random and purposive sampling methods. Data was analyzed and interpreted in relation to the objectives of the study and the hypothesis. The objectives of the study were reached and conclusions were made. The findings of the study revealed that community socio-economic development is understood by most of the residents in the area of Bugesera as confirmed by the respondents. It was further found out that Bugesera ADP/World Vision Rwanda has done a lot towards the transformational of Bugesera district in as far as development is concerned like construction of schools, building partnership sprit, fostering community ownership of developmental activities to mention but few. Findings showed the extent to which World Vision Rwanda through ADPs collaborate with other stakeholders have done in the socio-economic development in Bugesera district. Findings continued to show that there is high rate of collaboration most especially with community Based Organizations (CBOs) and Faith Based Organizations (FBO5). These xiii CBOs and FBOs are strong partners in the development process both as beneficiaries and also as implementing partners. The findings led to the affirmation of the only hypothesis that ADPs have and are still playing a significant role in communities’ development. Although there has been a lot of progress, there are several hindrances that were identified by respondents such as lack of enough finds of the stakeholders for socio-economic development for the community in Bugesera area. As such, policy makers should look forward to increase the efforts on community transformational development not only in the Bugesera but also in other parts of the country where this approach to development is used
