This publication assesses progress towards Sustainable Development Goal 4 (SDG 4) on education and its ten targets, as well as other related education targets in the SDG agenda. It addresses inclusion in education, drawing attention to all those excluded from education, because of background or ability. The report is motivated by the explicit reference to inclusion in the 2015 Incheon Declaration, and the call to ensure an inclusive and equitable quality education in the formulation of SDG 4, the global goal for education. It reminds us that, no matter what argument may be built to the contrary, we have a moral imperative to ensure every child has a right to an appropriate education of high quality.
