The Indian Administrative Service (IAS) is the main civil service of the Government of India. The Indian Administrative Service is the permanent administrative arm of the Union and State governments.
It is also regarded as the most prestigious and favored position in the country. This elite corps serves as the key bureaucratic pillar for translating the government’s political intent into administrative reality.
What is the IAS? (The Structure and Foundation)
The IAS forms the premier cadre that carries out administrative duties and public service across the vast machinery of the government of India. The service is fundamentally relied upon for the effective implementation of policies at the sub-state level of governance.
An All India Service: Serving Both Centre and State
The IAS is acknowledged as one of the three arms of the All India Services, along with the IPS and IFoS. The All India Service has a special status under the Constitution of India, as provided in Article 312.

The distinguishing feature of an All India Service is a dual accountability structure. IAS officers are enlisted by the Central Government but posted to a particular State Cadre for local administration.
The scheme provides service opportunities to the Central Government (Union) and the states. This allows for service versatility and national integration.
The Ladder: From Trainee to Top Boss
The career path of an IAS officer is well-defined and highly structured, with steps that depend on merit and seniority. It starts with compulsory training and field-level work.
The entry-level positions are generally at the sub-division level, where a probationer works as a Sub-Divisional Magistrate (SDM) or Assistant Collector at the beginning of their career.
The officer then proceeds to the mid-level apex field post of the District Collector (DC) or District Magistrate (DM), who serves as the overall administrative head of the district.
When officers reach the Senior Level (Secretariat), they are assigned to strategic roles in either the state or the central government, e.g., Principal Secretary or Chief Secretary (the administrative head of the state). They can also be assigned as Secretary to the Government of India.
The ultimate aim is to reach the highest position in the country’s civil service, which is becoming the Cabinet Secretary of India.
What Does an IAS Officer Actually Do? (Key Jobs)
The job profile of an IAS officer is incredibly expansive and can be highly diverse depending on the assignments they receive at any given time. The central role is to ensure effective management and execution of governmental affairs to serve the public interest.
The Collector/DM Role
An IAS officer serves as the District Collector or District Magistrate (DM) and acts as the government representative for the district. The officer will coordinate all services and direct the district’s overall administration.
This focus on the field role includes three major, related functions. First, the officer serves as the Revenue Head of the district, in charge of all records of land, revenue, and taxes within the district, including land acquisition.
The second function is for the DM to act as the Executive Magistrate, serving as a direct partner with the police department in Law & Order and maintaining public peace.
Finally, the DM serves as the district’s Development Leader, organizing all government welfare and infrastructure projects related to roads, hospitals, and schools to effectively advance development for all citizens.
The Secretariat Role
Most Senior IAS officers work in either the state capital region or New Delhi, where they are assigned to the Central or State Ministries and various government departments. In the Secretariat, their main task is to convert the political vision and electoral promises of the Ministers into detailed, actionable schemes, policies, and supporting laws.
They are fundamentally responsible for policy formulation and implementation, managing the resources and budgets assigned to their departments, and the development and delivery of large-scale schemes, such as the National Health Mission or a major infrastructure project, from concept to execution.
IAS vs. IPS
The IAS and the Indian Police Service (IPS) are both important parts of the civil services, recruited through the same UPSC examination, but their domains are different.
IAS deals with general administration, policy making, public service delivery, and overall government coordination as the administrative head of departments. IPS is responsible for policing, law enforcement, and security by leading and managing police forces.
The DM (IAS) and the Superintendent of Police (SSP/SP) (IPS) work closely together in districts to manage public affairs. Generally, the DM (IAS) is responsible for the overall coordination of all government departments in a district, giving the IAS officer a superior coordinating position over the IPS officer in the district administration.
What is the IAS Salary?
The salary structure of the IAS officer is based on the Consolidated Pay Levels suggested by the 7th Central Pay Commission, which is well above average and considered very attractive.

The entry point of Level 10 for a new IAS officer is INR 56,100 per month. Basic pay does not include allowances that would be in addition to basic pay, such as Dearness Allowance (DA) or House Rent Allowance (HRA).
With experience and time up the administrative ladder, IAS officers will receive pay increases as they move up, until they reach a fixed basic Cabinet Secretary salary of INR 2,50,000 per month.
How to Become an IAS Officer
The Indian Administrative Service can be entered almost exclusively by the highly competitive Civil Services Examination (CSE). This comprehensive exam is conducted once a year by the Union Public Service Commission (UPSC).
Basic Eligibility Rules
The UPSC maintains specific criteria that all aspirants must meet to be considered eligible for the examination.
| Eligibility Aspect | Criteria |
|---|---|
| Qualification | A candidate must hold a minimum of a Bachelor’s Degree in any discipline from a university recognized by the government. |
| Age | Candidates must be a minimum of 21 years old. The maximum age is generally 32 years for the General Category, with relaxations provided for reserved categories. |
| Attempts Allowed | General Category candidates are permitted six attempts. OBC Category candidates are allowed nine attempts, and SC/ST Categories receive unlimited attempts until they reach their respective upper age limit. |
The Three Steps to Selection
The three-stage selection process is carefully administered to assess candidates’ conceptual knowledge, writing ability, and personality traits necessary for efficient, high-level public service.
Step 1: Prelims (The Screening Test)
The Preliminary Examination is the initial objective test that filters a significant number of applicants. It consists of two objective-type question papers: General Studies (GS) and the Civil Services Aptitude Test (CSAT).
This stage is purely a screening process, and candidates must meet a cutoff in the GS paper and secure at least 33% marks in the CSAT paper to qualify.
Step 2: Mains (The Written Exam)
Candidates who successfully qualify in the Prelims proceed to the Mains, which is a descriptive written exam format. It includes nine papers, including an Essay, four General Studies papers, and two selected optional papers.
The Mains examination carries high scoring potential, thus it is the primary basis for each candidate’s final merit ranking.
Step 3: Personality Test (The Interview)
The last stage is the Personality Test (or interview), which carries 275 marks. This is a full-fledged face-to-face interview with the UPSC board. The purpose is to gauge the candidate’s administrative, reasoning, and general awareness, as well as their overall suitability for public service.
Finally, the merit list is prepared by combining the scores obtained during the Mains and the Personality Test.
Conclusion: Why the IAS Journey is Worth the Effort
Beyond being merely a career, the IAS offers an essential opportunity to influence national policy and make a contribution. The capacity of an IAS officer to personally impact millions of people’s lives through governance and policy implementation is what gives this service its true value.
Becoming an IAS officer is a challenging and rigorous route that requires years of earnest, meticulous planning for the profession’s stability. The authority and scope for the public good are unparalleled.
The secret to achieving this goal of fulfilling public service is consistent, hard work, centred on a thorough and impartial grasp of administration.
