Over 1,300 factual errors have been identified during the ongoing review of school textbooks published by the National Council of Educational Research and Training (NCERT). Stating that the council will correct the errors, human resource development minister Prakash Javadekar said nearly 900 teachers had sent over 2,500 suggestions for correction in textbooks. Earlier this year, NCERT decided to review all its books as they were written over a decade ago and needed to be updated. The books were published in 2007, post the National Curriculum Framework (NCF), 2005. The council had sought suggestions from teachers for factual errors and updation.
