Education provided by private proprietors or enterprises is neither free nor equitable and the Special Rapporteur welcomes the proposal of the Open Working Group on Sustainable Development Goals to ensure, by 2030, that all girls and boys complete free, equitable and quality primary and secondary education leading to relevant and effective learning outcomes, as well as to ensure inclusive and equitable quality education and promote lifelong learning opportunities for all (see A/68/970 and Corr.1, goal 4 and target 4.1). The underlying obligation for States to realize the right to education, including through enhanced public investment in education as an essential prerequisite, must be emphasized.
