In this rapidly changing world, it is difficult to address uncertainties and problems effectively through the traditional bureaucracies; it requires working together. Intersectoral collaborative efforts are increasingly seen as a solution to the most pressing problems (including illiteracy), facing contemporary societies and the results are promising. Therefore, it is important to nurture collaborative culture to achieve promising achievements in every endeavor. This research work therefore focuses on intersectoral collaboration in adult education in Ethiopia. Particularly, this research based book provides detailed information about the participation of different government sectors in the provision of adult education program and the major deterring factors. Finally, the book also pointed out research-based possible strategies to enhance the collaboration of the sectors in adult education.
