Hello Aspirant,

See to answer your question first of all let me make you clear that CBSE is an educational board of national level whereas the National Council of Educational Research and Training (NCERT) is an autonomous organization set up in 1961 by the Government of India to assist and advise the Central and State Governments on policies and programmes for qualitative improvement in school education. CBSE does not publish books instead the work of Central Board of Secondary Education to analyze and monitor the performance of academic activities, to conduct examinations, develop norms for various educational activities and many others which you can check out from the official website of CBSE which is as given below :-
