SDG 4, or Quality Education, is a UN goal to ensure inclusive, equitable, and quality education for all and to promote lifelong learning. While some progress has been made, change is slow and uneven, with significant disparities in access and quality. Key areas of focus include completing free primary and secondary schooling, providing technical and vocational skills, achieving universal access to learning, and expanding lifelong learning opportunities. Challenges include lack of infrastructure, outdated curricula, gender disparities, and the digital divide.
