NITI Aayog: Role, Structure and Functions

Updated 11 October 2026 · Fact-checked

NITI Aayog (National Institution for Transforming India) is the Government of India's policy think tank. It replaced the Planning Commission on 1 January 2015. It advises the Centre and States, promotes cooperative federalism, and works through a bottom-up approach instead of imposing top-down plans and fund allocation.

Understand NITI Aayog: Role, Structure and Functions

India followed centralised planning for decades. The Planning Commission, set up in 1950, prepared Five Year Plans and decided how funds were shared with States. Over time this was seen as a one-size-fits-all, top-down model. States felt they had little say.

In 2015 the Government replaced it with NITI Aayog. NITI stands for National Institution for Transforming India. It was created by an executive resolution of the Union Government, not by an Act of Parliament. It is a policy think tank and advisory body. It does not run a Plan-fund allocation system like the old Commission.

The idea behind it is cooperative federalism. The Centre and States work as partners. States take part in policy making through the Governing Council, which has the Prime Minister as Chairperson and includes Chief Ministers of all States and Union Territories with legislatures, plus Lieutenant Governors of the other Union Territories. NITI Aayog also supports competitive federalism by ranking States on indicators such as the SDG India Index, so States learn from each other.

Structure in brief: the Prime Minister is Chairperson; there is a Vice-Chairperson, full-time Members, part-time Members, Ex-officio Members (Union Ministers nominated by the PM), a Chief Executive Officer of the rank of Secretary to the Government of India, and Special Invitees. Regional Councils may be formed for specific issues that affect more than one State, and they are convened by the Prime Minister.

For the exam, think in three blocks: why it replaced the Planning Commission, who sits in it, and what it does (advice, vision, States' participation, monitoring, innovation).

Worked examples

Example 1

Distinguish between the Planning Commission and NITI Aayog. (5 marks)

Show the solution

Start with the basic fact: the Planning Commission was set up in 1950 and NITI Aayog replaced it on 1 January 2015.
Compare nature: the Planning Commission was a centralised planning body; NITI Aayog is a policy think tank and advisory body.
Compare approach: the Planning Commission followed a top-down model; NITI Aayog follows a bottom-up approach.
Compare role of States: earlier, States had limited say in plans; now Chief Ministers sit in the Governing Council as partners.
Compare focus: the Planning Commission centred on Five Year Plans and allocation of resources; NITI Aayog focuses on strategy, long-term vision and monitoring.

Answer: The Planning Commission was a top-down body that prepared Five Year Plans and guided resource allocation, with limited State participation. NITI Aayog is a think tank that gives policy advice, works bottom-up and involves States through the Governing Council, promoting cooperative federalism.

Example 2

Explain how NITI Aayog promotes cooperative federalism. (5 marks)

Show the solution

Define the term: cooperative federalism means the Centre and States work together as equal partners in policy making.
Show the structure: the Governing Council has the Prime Minister as Chairperson and includes Chief Ministers and Lieutenant Governors, so States take part in national policy discussions.
Mention Regional Councils: they are formed for issues that concern more than one State and are convened by the Prime Minister.
Add the bottom-up approach: plans are meant to be built from village and State level inputs instead of being imposed from above.
Add competitive federalism: indices such as the SDG India Index let States compare performance and learn from each other.

Answer: NITI Aayog promotes cooperative federalism by giving States a seat in the Governing Council, using Regional Councils for shared issues, following a bottom-up approach and encouraging healthy competition between States through performance indices.
