Right to education, which is an integral part of UNESCO's constitutional mission of ensuring "full and equal opportunities for education for all," is at the core of the Education for All process. While reforming education polices as part of this process, many countries have modernized and developed national legislation, often with technical assistance provided by UNESCO. As a strategic objective of Education for All, doing so strengthens foundations of the right to education in national legal systems. It brings to light the fundamental principle of the equality of educational opportunities, enshrined in UNESCO's Convention Against Discrimination in Education, a key pillar of Education for All.
