Sustainable Development Goal 4 (SDG 4 or Global Goal 4) is about quality education and is among the 17 Sustainable Development Goals established by the United Nations in September 2015. The full title of SDG 4 is "Ensure inclusive and equitable quality education and promote lifelong learning opportunities for all". SDG 4 has ten targets which are measured by 11 indicators. The seven "outcome-oriented targets" are: free primary and secondary education; equal access to quality pre-primary education; affordable technical, vocational and higher education; increased number of people with relevant skills for financial success; elimination of all discrimination in education; universal literacy and numeracy; and education for sustainable development and global citizenship. The three "means of achieving targets" are: build and upgrade inclusive and safe schools; expand higher education scholarships for developing countries; and increase the supply of qualified teachers in developing countries.

In Western Asia and North Africa, the ongoing armed conflict has seen an increase in the number of children who are not attending school. Sub-Saharan Africa made the greatest progress in primary school enrolment among all developing regions – from 52 percent in 1990, up to 78 percent in 2012, but large disparities still remain. Background "Education for All" has been a popular slogan and has been given attention through different international development courses ever since 1990. It was considered critical at the inception of the Sustainable Development Goals (SDGs) and tagged SDG 4. Education is seen as a force for sustainable development, nation-building and peace. Children and young people who gain certain skills such as reading, writing, or counting are more likely to have a better future than their peers who lack these skills.
