Either one of the mother tongue or the local/regional language will be the medium of instruction up to Class 5 in all schools, the government said Wednesday while launching the National Education Policy 2020. Among other changes in the revision of the NEP, last done over three decades ago, is the extension of right to education to cover all children between three and 18 years of age. The policy also proposes vocational education, with internships, for students from Class 6, a change to the 10+2 schooling structure and a four-year bachelor's programme.
