The National Council of Educational Research and Training (NCERT) provides academic and technical support for qualitative improvement of school education. The NCERT was established in 1961 as an apex national body to lead qualitative changes in school education. NCERT has been playing an advisory role guiding central and state governments in formulating policies, acts and government programmes. It has played a crucial role in the development of national policies on education (1968-1986) and national curriculum frameworks. The researches undertaken by the Council have led to building new perspective of schooling and also provided inputs for formulation of policies and programmes. NCERT has been designing and offering innovative and need-based courses for teachers, teacher educators and counsellors.
