The Three Language Formula in Indian Schools

Reference library · 1032 words

India has no single national language. The Constitution names Hindi in the Devanagari script as the official language of the Union, with English retained for official purposes, and it lists a further set of languages in its Eighth Schedule, a list that has grown by amendment to twenty two entries including Bengali, Telugu, Marathi, Tamil, Urdu, Gujarati, Kannada, Malayalam, Odia, Punjabi, Assamese, Maithili, Santali, Bodo, Dogri and others. Each state may choose its own official language or languages. Into this arrangement steps a piece of education policy that has shaped what tens of millions of children study every year since the 1960s: the three language formula.

The idea is simple to state and endlessly difficult to apply. Every school child should learn three languages: the regional language or mother tongue, Hindi, and English, with the balance adjusted so that children in Hindi speaking states also learn a modern Indian language from elsewhere in the country, usually a southern one. The formula was refined by the Central Advisory Board of Education and given its best known articulation in the National Policy on Education of 1968, which followed the report of the Education Commission chaired by the scientist D. S. Kothari. It has been restated, with variations, in the policies of 1986 and 1992 and again in the National Education Policy of 2020.

Why the formula was invented

The formula was a peace treaty as much as a pedagogical scheme. When the Constitution came into force in 1950, it provided that English would continue for official Union purposes for fifteen years, that is until 1965, after which Hindi was expected to take over. As that date approached, the prospect of a Hindi only administration alarmed the non Hindi speaking south, where Hindi is not a mother tongue and where the Dravidian languages have their own long literary traditions. Tamil Nadu, then Madras State, saw large and at times violent anti Hindi agitations in January and February 1965, with student protests, deaths, and lasting political consequences: the Dravida Munnetra Kazhagam won the 1967 state election and Congress has not governed the state since. Parliament responded with the Official Languages Act of 1963 and its 1967 amendment, which effectively guaranteed that English would continue indefinitely alongside Hindi so long as any non Hindi state wished it.

The three language formula belongs to the same moment. Its logic was reciprocity. If southern children were asked to learn Hindi, northern children should be asked to learn a southern language, so that the burden of national integration fell on everyone rather than on one region. The formula also carried a second and quieter purpose drawn from educational research: children learn most securely in a language they already speak, so the first of the three languages was meant to be the mother tongue or the regional language, not English.

What actually happens in classrooms

Implementation has been uneven in a way that undermines the original bargain. In most Hindi speaking states, the third language slot was filled not by Tamil or Telugu or Kannada but by Sanskrit, which is comparatively easy to score in, is taught by available teachers, and carries cultural prestige. Very few schools in Uttar Pradesh, Bihar, Madhya Pradesh or Rajasthan have ever taught a southern language at scale. Meanwhile Tamil Nadu has refused the formula outright since the late 1960s and follows a two language policy of Tamil and English. It is the most prominent holdout, and its refusal has been consistent across governments of different parties.

Elsewhere the formula operates but often in name. In many private English medium schools, English is the medium of instruction, the regional language and Hindi are taught as subjects, and the third language is dropped or reduced after the middle years. Public examinations at the end of class ten frequently allow the third language to be discontinued. Teacher supply is the binding constraint: a state cannot offer Kannada in Patna if there is nobody qualified to teach it. Textbook availability, examination boards, and the sheer crowding of the timetable all push in the same direction.

The National Education Policy of 2020 restated the formula while stressing flexibility. It says no language will be imposed on any state, that at least two of the three should be native to India, and it puts strong emphasis on mother tongue or local language as the medium of instruction at least through the early primary years. Critics in the south read the policy as a soft reintroduction of Hindi, and the dispute flared again in 2025 over Tamil Nadu's continued refusal and its consequences for centrally funded schemes. Supporters point out that the policy text explicitly disclaims imposition. The disagreement is genuinely unresolved and turns less on the words of the policy than on trust between the Union and the states.

The deeper argument about language and opportunity

Underneath the federal quarrel sits a harder question about mobility. Parents across India, including in villages, increasingly want English for their children, because English is the language of the courts above the district level, of much of the private sector, of software, of higher education in medicine and engineering, and of migration. Educationists counter that early instruction in an unfamiliar language produces children who can decode text without comprehending it, a pattern visible in the Annual Status of Education Report surveys conducted by the non governmental organisation Pratham, which have repeatedly found large proportions of rural children in upper primary classes unable to read a simple paragraph fluently.

So the three language formula is asked to do three incompatible things at once: protect the mother tongue for the sake of learning, spread a link language for the sake of the union, and deliver English for the sake of employment. It has succeeded most clearly at the first task where states have taken it seriously, has largely failed at the second because reciprocity was never honoured in the north, and was never designed for the third. For Indian families abroad, the formula is also part of why an Indian migrant may arrive with fluent English, a regional mother tongue, and only schoolbook Hindi, a combination that often surprises those who assume a single Indian language exists.
