The aim of the paper is to discuss the system of double-shift schooling and assess it from economic, social and educational angles referring to different cases from Sub-Saharan African countries. The paper makes an attempt to prove that despite certain challenges that it faces, the system of double-shift schooling is the best solution for poor countries to achieve the millennium goal of Education for All with limited resources, and an optimum strategy for rich countries to use resources more efficiently. Thus, if wisely implemented and managed, double-shift schools can be the best way to achieve the goal of universal education in both poor and rich countries. (Contains 1 footnote.)
