Coimbatore: Tirupur MP K Subbarayan on Monday requested the Union government to make Tamil a compulsory subject for students in classes I to X in Kendriya Vidyalaya schools in the state. In a petition to Union education minister Dharmendra Pradhan, Subbarayan said that most of the 49 Kendriya Vidyalaya schools in the state do not teach Tamil as a subject. “The schools have been following a three-language formula – English and Hindi as compulsory from Class I to XII. Sanskrit is taught from Class VI to VII and goes on to be optional till Class X. As per rules, if there are a minimum of 20 students who opt to learn Tamil, arrangements should be made to teach it. It is very partisan,” the petition said.
