The National Council of Educational Research and Training (NCERT) is the apex body in India for curriculum-related matters for school education.
NCERT is responsible for developing and publishing the National Curriculum Framework (NCF).
Based on the NCF, NCERT designs syllabi and publishes textbooks that are widely used in schools across India, especially those affiliated with the Central Board of Secondary Education (CBSE).
Therefore, NCERT is the national-level body that suggests the curriculum for school education for the nation.
NCTE deals with teacher education, NUEPA deals with educational planning and administration, and SCERT operates at the state level.
