Education is a Concurrent List subject, yet language policy repeatedly triggers Centre-State friction. Examine this tension with reference to the three-language formula.

Education appears in Entry 25 of the Concurrent List, Seventh Schedule [1], making school policy a shared responsibility. Yet language, being tied to identity rather than administration alone, converts this shared space into contested ground — as the ongoing controversy over the three-language formula shows.

Why concurrent status itself breeds friction

• Asymmetry of instruments: the Centre sets curricular direction through NEP 2020 and the NCFSE 2023 [2][4], while states finance, staff and run the schools — vision and delivery sit in different hands.
• Policy versus statute: NEP is executive policy, not law, but central boards operationalise it through binding circulars, giving it practical force states never legislated on.

The formula as the recurring flashpoint

• Originating in NEP 1968 and reaffirmed in NEP 2020, it requires three languages, of which at least two must be native to India [2][4].
• NEP explicitly promises flexibility and that no language will be imposed on any State [3], yet non-Hindi states — Tamil Nadu foremost — read it as Hindi imposition, echoing the anti-Hindi agitations of 1965.
• Capacity gaps deepen distrust: without qualified third-language teachers and materials, rural and under-resourced schools bear the cost of a mandate framed centrally.

Implementation and the judicial check

• CBSE's rollout from Class 6 (2026-27), with a mandatory third-language Class 10 examination by 2031, and shifting circulars on Classes 9–10, invited litigation.
• In August 2026, a Supreme Court bench led by Justice Joymalya Bagchi urged CBSE to consider a one-time reprieve for Class 6, questioned classifying English as "non-indigenous", and asked the Centre, CBSE and NCERT for a readiness roadmap — nudging implementation without striking down the policy [5].

The friction, therefore, is less about the formula's merit than about consultation and sequencing. Genuine consultative rulemaking with states, bilateral teacher-exchange agreements envisaged in NEP itself [2], and readiness audits before each phase can reconcile multilingual competence with linguistic dignity — the essence of cooperative federalism.
