Important historical milestones in education reform for UPSC candidates include the establishment of the University Grants Commission (UGC) in 1956 and the Right to Education Act in 2009. These reforms have significantly increased access to quality education and emphasized the importance of education in national development. The National Policy on Education, introduced several times, has also played a crucial role in shaping educational strategies. Being aware of these milestones can help candidates understand broader socio-political contexts, which is valuable for UPSC preparation.
