The three-language formula seeks to promote multilingualism, yet it has repeatedly triggered federal friction. Critically examine in the context of NEP 2020.

The three-language formula (TLF) was first adopted under the National Policy on Education, 1968. NEP 2020 restated it, adding a pledge that "no language will be imposed" [1]. The goal of multilingualism is sound. Most of the friction comes from how the formula is enforced, not from the idea itself.

Strengths: how the TLF promotes multilingualism

• Better learning: NEP prefers the mother tongue or regional language as the medium of instruction at least till Grade 5, and preferably till Grade 8 [1]. UNESCO finds that learning gains last only with at least six years of mother-tongue teaching [2].
• Flexibility: States, regions and students choose the languages. Sanskrit and foreign languages are offered as options [1].
• National integration: Learning another region's language supports mobility and cultural understanding. NCF-SE 2023 gives renewed emphasis to multilingualism [1].
• Constitutional fit: The formula matches Art. 350A, which provides for instruction in the mother tongue at the primary stage.

Weaknesses: sources of federal friction

• Fear of Hindi imposition: In non-Hindi States, the third language often ends up being Hindi. Tamil Nadu has kept a two-language policy for decades.
• Recommended vs. compulsory: The Union has told Parliament that the TLF is only "recommendatory" for States [3]. When the CBSE made the third language (R3) count in its Board exams across 28,819 schools, the advice became a binding rule [4].
• Funding pressure: Some States see the link between central school funds (Samagra Shiksha, PM SHRI) and adopting NEP as coercive federalism.
• Capacity gaps: Many schools lack trained teachers for the chosen language. Even by the government's own figure, 1.2% of CBSE schools are not ready [4].
• Burden on learners: On 28 Sept 2026, the Supreme Court extended the R3 relaxation to Class 6: the third language will be assessed only internally, with no Board pass/fail. The Bench said children must be "comfortable", not merely able to "adapt" [4].

Way forward

• Keep teaching the language but lower the stakes: use internal assessment and report skill levels instead of pass/fail.
• Cooperative federalism: respect States' choice of languages and separate central funding from language decisions.
• Readiness-based rollout: set time-bound transitions linked to teacher availability.

The TLF's teaching logic is sound. Friction arises when a recommended formula is turned into a compulsory exam or a condition for funding. If it is implemented with flexibility, consultation and child-centred assessment, as NEP's own "no imposition" clause intends, it can deliver multilingualism in the spirit of unity in diversity and SDG 4 (inclusive, quality education).
