TNPSC Indian polity: topics, articles and how to prepare

By the PrepMatic team · Updated 8 Oct 2026 · 9 min read

Indian Polity is Unit IV of the General Studies part in the current TNPSC Group 4 and Group 2 and 2A prelims, with about 15 of the 75 questions. In Group 4 that is roughly 22 marks out of 300. It is a stable, well-defined subject: the Constitution does not change much from year to year, and questions repeat the same articles, bodies and landmarks in different words. That makes polity one of the most dependable units to master.

Where Indian polity appears

TNPSC calls the question counts indicative. Older ten-unit syllabus lists number polity as Unit V, but the current schemes number it Unit IV. For the full unit list, see the Group 4 syllabus and Group 2 syllabus pages.

The syllabus in six blocks

The Commission's revised Group 4 scheme (January 2022) lists polity in six lines. Check Annexure III of the latest notification for any change.

A map of the Constitution

Learn the Parts and article ranges before you learn individual articles. Once you know where a subject sits, you can place most articles.

The Constitution was adopted on 26 November 1949 and came into force on 26 January 1950, with B. R. Ambedkar chairing the Drafting Committee. It began with 395 articles, 22 parts and 8 schedules and now has 12 schedules. The words Socialist, Secular and Integrity were added to the Preamble by the 42nd Amendment (1976).

Articles that recur

Two facts worth separating: Right to Property was removed from the Fundamental Rights by the 44th Amendment (1978) and is now a legal right under Article 300A. And the Preamble, held not to be part of the Constitution in the Berubari case (1960), was held to be part of it in Kesavananda Bharati (1973).

Union and State machinery

For the President, learn that the election is indirect through an electoral college of elected members of Parliament and the State Legislative Assemblies, the minimum age is 35 and the term is five years. For Parliament, learn that the Lok Sabha has 543 elected seats, the Rajya Sabha is a permanent house with one-third of its members retiring every second year, and Money Bills start only in the Lok Sabha.

For Tamil Nadu, the legislature is unicameral. The Assembly has 234 constituencies, and the Legislative Council was abolished in 1986. The state sends 39 members to the Lok Sabha and 18 to the Rajya Sabha. The Governor is appointed by the President, while the Chief Minister is appointed by the Governor.

Federalism and Centre-State relations

Learn the three lists of the Seventh Schedule (Union, State and Concurrent), the Sarkaria Commission (1983) and the Punchhi Commission (2007) on Centre-State relations, and the Inter-State Council under Article 263. The GST Council (Article 279A, introduced by the 101st Amendment) is a current example of cooperative federalism. Tamil Nadu connects to this topic through the Rajamannar Committee, which the state appointed in 1969 to examine Centre-State relations. The money side of federalism, such as the Finance Commission and tax sharing, is in the Indian economy guide.

Local government and Tamil Nadu

This is the topic that links the syllabus to the state. The 73rd Amendment added Part IX on Panchayats and the 74th added Part IXA on Municipalities, both in force in 1993. They give local bodies constitutional status, regular elections run by a State Election Commission, a State Finance Commission, and reservation of seats for SC, ST and women. Article 40 in the Directive Principles is the root of the idea.

In Tamil Nadu, rural local government follows the Tamil Nadu Panchayats Act, 1994, with three tiers: the village panchayat, the panchayat union and the district panchayat. Urban bodies are corporations, municipalities and town panchayats. Women's reservation in local bodies is one-third under Article 243D and the state has raised it by its own law, so check the current provision. The Uthiramerur inscription of the Chola period, covered in Tamil Nadu history and culture, is the historical example of village self-government. How these bodies deliver schemes is in development administration.

Elections, judiciary and accountability

• Elections: the Election Commission is a constitutional body (Article 324). The voting age is 18 after the 61st Amendment (1988), and the Tenth Schedule on anti-defection came with the 52nd Amendment (1985).
• Courts: the Supreme Court and High Courts can issue five writs: habeas corpus, mandamus, prohibition, certiorari and quo warranto. The Madras High Court has its principal seat in Chennai and a bench at Madurai. Public interest litigation and Lok Adalats extend access to justice. Rule of Law means that everyone, including the government, is subject to law.
• Accountability: the Lokpal and Lokayuktas Act, 2013; the Right to Information Act, 2005; the Consumer Protection Act, 2019, which replaced the 1986 Act and works through District, State and National Commissions; the Protection of Human Rights Act, 1993, which created the NHRC and State Human Rights Commissions; and the 106th Amendment (2023) on women's reservation in legislatures.

Learn constitutional bodies and statutory bodies as two lists. Constitutional bodies include the Election Commission, the UPSC and State Public Service Commissions (TNPSC is one, under Article 315), the Finance Commission, the CAG and the Attorney General. Statutory bodies such as the NHRC and the Lokpal exist under Acts of Parliament.

How to study polity

1. Start with the Civics portions of the Samacheer Kalvi Social Science books for Classes 6 to 10, which cover most of the SSLC-standard syllabus. For Group 2, add a standard reference such as M. Laxmikanth's Indian Polity. See best books for TNPSC for more.
2. Memorise the Parts table first, then the articles table. Revise both weekly.
3. Keep a list of amendments, committees and Acts with the year and one line each. Questions often ask "which amendment" or "which committee".
4. Link current affairs to polity. Court judgments, new Acts and constitutional appointments are reported in the news; follow the routine in the current affairs guide.
5. Practise statement questions. A typical question gives three statements and asks which are correct. Check each one separately.
