Education was positioned as Goal 4 (i.e., SDG4) in SDGs. SDG4 aims to “ensure inclusive and equitable quality education and promote lifelong learning opportunities for all.” The lack of education and the inability to read and write often limit access to information and disadvantage the livelihoods of people. From the perspective of acquiring knowledge and skills, along with developing human resources, it is clear that the elements of education are present across all 17 SDGs. In other words, education is a cross-cutting discipline that influences a variety of areas (Kitamura et al. 2014) and, as such, plays an important role in achieving all SDGs. The main objective of this chapter in the book 'Sustainable Development Disciplines for Humanity' is to examine “inclusive and equitable quality education.” First, this chapter provides a brief overview of international trends in educational cooperation from 1945 to 2015, covering the Education for All (EFA), Millennium Development Goals (MDGs), and SDGs. It then discusses “inclusive and equitable quality education,” the core of SDG4. It specifically addresses discussions on equity, inclusion, and the quality of education. Furthermore, the quality of education is examined from four perspectives: school environment, educational attainment, learning achievement, and non-cognitive skills. This chapter also presents the case of education for children with disabilities in Ethiopia.
