The 2030 Agenda for Sustainable Development focuses on leaving no one behind with its Goal 4 on education calling upon education systems ‘to ensure inclusive and equitable quality education and promote lifelong learning opportunities for all’. With ten years remaining to the target date of 2030, countries need to step up e¬orts to reach out to all learners, respect their diverse needs, abilities and characteristics and eliminate all forms of discrimination in the learning environment. This requires adopting an inclusive approach whose foundations have been laid by the UNESCO World Conference on Special Needs Education held in Salamanca, Spain, in 1994. The publication looks at the past, present and future since Salamanca. It provides examples from around the world and make recommendations to guide the further development of inclusive national policies and practices.
