This document discusses the MDG Goal 2 experience of universal primary education and implications for SDG4 on education. It summarizes the target and indicators for MDG 2 and progress made in increasing net primary enrollment globally and in Sub-Saharan Africa. Though targets were largely met, it argues we should consider broader impacts like greater transparency, state capacity, and disaggregated data. SDG4 expands beyond access to focus more on learning outcomes, skills, knowledge for sustainable development. An open question remains if countries can keep pace with SDG4's new, more demanding education goals.
