The UPSC Civil Services Examination (CSE) recruits candidates for prestigious positions across All India Services, Central Government Group A and Group B services. These services form the backbone of India’s administrative machinery and are specially classified with distinct roles, responsibilities, and hierarchies.
Understanding the various services offered through UPSC, including the All India Services like IAS, IPS, IFS, and the numerous Group A and B Central Services, is critical for aspirants to align their career aspirations and exam preparation goals.
The All India Services consist of three premier cadres:
Indian Administrative Service (IAS)
Indian Police Service (IPS)
Indian Forest Service (IFS)
Officers of these services are primarily allocated to State Governments (cadres) but do serve the Central Government. While state governments have day-to-day control, disciplinary powers rest solely with the Centre ensuring political neutrality and integrity.
The IAS officers are generalists holding top decision-making posts in district, state, and central administrations. Their roles include policy implementation, administration, revenue collection, and law & order maintenance.

| 1–4 | Assistant Secretary | Sub-Divisional Magistrate |
| 5–8 | Undersecretary | Additional District Magistrate |

| 25–30 | Additional Secretary / Principal Secretary | |
| 30–33 | Additional Chief Secretary | |
| 34–36 | Secretary | Chief Secretary |
| 37+ | Cabinet Secretary of India |
IPS officers are responsible for law enforcement, crime prevention, public safety, and security. They hold various ranks ascending from Assistant Superintendent of Police (ASP) to Director General of Police (DGP).
| Rank | Full Form | Years of Service |
|---|---|---|
| ASP | Assistant Superintendent of Police | 2–3 |
| DSP | Deputy Superintendent of Police | 5–7 |

| IG | Inspector General of Police | 20–22 |
| ADG | Additional Director General of Police | 23–25 |
| DGP | Director General of Police | 25+ |
IPS officers may also serve in intelligence agencies such as RAW, IB, and Central Armed Police Forces (CAPF).
IFS officers manage forestry, wildlife conservation, and environmental policies. They wield administrative, financial, and judicial powers in their domain, working under the Ministry of Environment, Forest and Climate Change.
These officers serve exclusively under the Central Government and occupy specialized roles. Some prominent Group A services include:
Indian Foreign Service (IFS)
Indian Revenue Service (Income Tax & Customs)

Indian Civil Accounts Service (ICAS)
Indian Corporate Law Service (ICLS)
Indian Defence Accounts Service (IDAS)
Indian Information Service (IIS)
Indian Postal Service (IPoS)
Indian Railway Personnel Service (IRPS)

The IFS officers serve as diplomats representing India abroad, promoting national interests in political, economic, and cultural spheres. Their career progression involves postings to embassies, consulates, multilateral organizations, and ambassadorial roles.
Each service comes with unique training, responsibilities, and career prospects aligned with government priorities. For example, IRS officers manage tax administration, IA&AS officers conduct financial audits for government departments, and IPoS officers manage the India Post network.
Group B services are mainly gazetted officers with sub-ordinate roles supporting Group A services. These include:
Armed Forces HQ Civil Service (AFHCS)
Delhi, Andaman and Nicobar Civil Service (DANICS) & Police Service (DANIPS)
Pondicherry Civil Service (PONDICS) & Police Service (PONDIPS)
