About NCERT & its books
The words above are remarkably true in today’s society. The Central Board of Secondary Education prepares the textbooks for all the classes which are called the NCERT books. NCERT (National Council of Educational Research and Training) is an autonomous organisation of the Government of India that was established on the 1st of September, 1961 as a literary, scientific and charitable society under the Societies’ Registration Act. The headquarters are located in New Delhi.
NCERT assists and advises the central and state governments on the academic matters related to the school education. The NCERT was established with the agenda to design and support a common system of education which is national in character and also encourages the diverse culture across the country. The publishers have been trying to enrich the curriculum for the overall development of the children so that it goes beyond the textbooks. They are trying to make the examinations more flexible and are integrating them with the classroom life.
