The document discusses India's Three Language Formula policy for promoting multilingualism and national integration. The policy recommends that in Hindi-speaking states, students learn Hindi, English, and one Modern Indian Language. In non-Hindi states, students learn the regional language, Hindi or English, and a Modern Indian Language. There have been implementation issues due to uneven adoption of the 3+1/-1 formula and preference for English. Fully implementing mother tongue education and managing the language load are ongoing challenges. Improving resources for teaching additional languages and making duration requirements consistent could help address non-implementation.
