Facing criticism for the "rationalisation" of school textbooks which dropped the chapters on 'Kings and Chronicles' and the 'The Mughal Courts' from the CBSE medieval History textbooks for Class 12, NCERT, the top advisory body for Centre and state on school education, today said it's a professional exercise meant to help students hit by the pandemic and has no ulterior political motive. "As we explained last year as well, there has been a lot of learning loss due to the Covid pandemic and the students underwent a lot of trauma. To help stressed students, and as a responsibility to society and the nation, it was felt that the content load in textbooks should be reduced," Dinesh Prasad Saklani, Director of NCERT, told NDTV.
