Explanation:

Haryana has become the first state in India to implement the three-language formula for students in Classes IX and X, in alignment with the New Education Policy (NEP) 2020. This significant decision reflects the state's commitment to enhancing educational standards and promoting multilingualism among students.

The three-language formula is a key component of the NEP 2020, which emphasizes the importance of linguistic diversity in education. Under this framework, students are required to learn three languages: two Indian languages and one foreign language, with the aim of fostering cultural understanding and communication skills. In Haryana's implementation, English and Hindi are designated as compulsory languages, while students can choose a third language from options such as Sanskrit, Punjabi, or Urdu. This choice allows for the inclusion of regional languages, thereby promoting cultural heritage and inclusivity.

The introduction of this policy is set to begin in the 2025-26 academic session for Class IX and will extend to Class X in the following academic year. This phased approach allows for a structured implementation, ensuring that schools are adequately prepared to support the new curriculum. Core subjects like Mathematics, Science, and Social Science will remain mandatory, while students will also have the opportunity to select vocational subjects, enhancing their educational experience and career readiness.
