4.3 Lifelong learning opportunities
Quality education and lifelong learning opportunities for all are central to ensuring a full and productive life to all individuals and to the realization of sustainable development. Despite considerable progress in school enrolment, millions of children remain out of school, especially where educational systems struggle to keep up with population growth. Even when more children are enrolled, many do not acquire the basic skills. Quality education is hampered by the lack of trained teachers and adequate school facilities.
