Explainer: What CBSE’s Three-Language Formula Means For Class 9 From July 1, Why Tamil Nadu Opposes It

Two months into the 2026-27 academic session, the Central Board of Secondary Education (CBSE) has officially notified the implementation of the three-language formula for Class 9 students from July 1, 2026. The move comes under the framework of the National Education Policy (NEP) 2020 and has once again brought the long-debated language policy into focus across India.

The decision affects both government and private schools affiliated with CBSE and raises several questions among students, parents and educators regarding language choices, foreign languages, textbooks and political concerns surrounding the policy.

What Is The Three-Language Formula?

The three-language formula is an educational policy that requires students to learn three languages during their school education. Under the National Education Policy 2020, at least two of these languages must be native to India.

The policy applies to schools across the country but gives flexibility to states and institutions in selecting the languages. According to the NEP, no language will be imposed on any state.

Traditionally, the formula included:

• The mother tongue or regional language
• An official language
• A modern Indian or European language

The central idea behind the policy is to encourage multilingualism, strengthen cultural understanding and promote national unity while respecting regional aspirations.

How Did The Three-Language Formula Begin?

The concept of the three-language formula is not new. It was first proposed by the Education Commission between 1964 and 1966, popularly known as the Kothari Commission.

It was later formally adopted under the National Policy on Education (NPE) 1968 during the tenure of former Prime Minister Indira Gandhi. The policy was reaffirmed in the National Policy on Education 1986 under Rajiv Gandhi and revised again in 1992 during the Narasimha Rao government.

Over the decades, the formula was projected as a way to balance regional languages with national integration and wider communication.

What Does NEP 2020 Say About Language Learning?

The National Education Policy 2020 strongly supports multilingual education and calls for the "early implementation of the three-language formula to promote multilingualism" from the school level itself.

The policy states that the formula will continue to be implemented "while keeping in mind the constitutional provisions, aspirations of the people, regions, and the Union, and the need to promote multilingualism as well as promote national unity".

At the same time, the NEP emphasises flexibility. It says the three languages chosen by students will depend on the choices made by states, regions and students themselves, provided at least two of the languages are Indian languages.

This means schools and states are expected to have a larger role in deciding language combinations rather than following a rigid national pattern.

What Changes For Students Under The New CBSE Rule?

One of the major changes introduced by CBSE is related to foreign languages and the status of English.

Under NEP 2020, students at the secondary level can study foreign languages such as Korean, Japanese, French, German and Spanish alongside Indian languages and English.

However, CBSE has now classified English as a foreign language within the framework. The Board has allowed only one foreign language as part of the three-language structure.

This could create limitations for students who previously wanted to study both English and another foreign language together within the mandatory language combination.

For example, students may now have to prioritise either English or another foreign language within the framework, depending on school offerings and policy interpretation.

Are Textbooks And Teachers Ready?

CBSE has clarified that dedicated R3 textbooks for Class 9 are not fully ready yet. Until these books become available, students will use the Class 6 R3 textbooks of the chosen language for the 2026-27 session.

The Board has also acknowledged the shortage of qualified native Indian language teachers in some schools.

As an interim arrangement, schools facing teacher shortages have been permitted to engage existing teachers from other subjects who have "functional proficiency" in the concerned language.

This temporary measure is expected to help schools manage implementation challenges during the initial phase of the rollout.

Why Has The Three-Language Formula Remained Controversial?

The three-language formula has repeatedly triggered political debates, particularly in Tamil Nadu.

The state has historically opposed policies perceived as attempts to impose Hindi. The roots of this resistance go back to 1937, when the then Madras government under C Rajagopalachari introduced compulsory Hindi in schools.

The decision led to widespread protests by the Justice Party and Dravidian leaders including Periyar. The compulsory Hindi policy was eventually revoked in 1940, but anti-Hindi sentiment continued to shape Tamil Nadu's language politics.

When the three-language formula was introduced nationally in 1968, Tamil Nadu strongly opposed it once again. Under then Chief Minister C N Annadurai, the state adopted a two-language policy focused only on Tamil and English.

Even today, Tamil Nadu remains the only state that has never implemented the three-language formula. The state continues to favour its long-standing two-language system and has consistently resisted attempts to include Hindi or other Indian languages within the school curriculum framework.

The latest CBSE implementation is therefore expected to revive discussions over linguistic identity, federal autonomy and the balance between national integration and regional preferences.
