"Consultations are on with the CBSE and the changes are likely to be implemented from next academic session," the source added.
Under the National Education Policy, the three-language formula means students in Hindi-speaking states should learn a modern Indian language, apart from Hindi and English and, in non-Hindi-speaking states, they should learn Hindi along with the regional language and English.
However, a majority of the 18,000 affiliated institutions offer the mother tongue or Hindi, English and a foreign language such as German and Mandarin up to Class 8.
Last December, the CBSE had sent the proposed three-language formula for secondary education to the HRD ministry setting off speculation over if as to when the new scheme would kick in.
Under the new plan, a student would have to take up three Indian languages listed in Eighth Schedule of the Constitution, one of which could be English.
