The Union Public Service Commission (UPSC) is the apex constitutional authority responsible for recruiting personnel to higher civil services, armed forces officer cadres, engineering cadres, and medical services under the Government of India.
Established under Article 315 of the Constitution of India, the commission acts as an independent recruiting body designed to conduct competitive examinations and advise the President of India on matters relating to appointments, promotions, and disciplinary cases.
Constitutional Mandate & Role of UPSC
Articles 315 to 323 of the Constitution delineate the powers, functions, and responsibilities of the UPSC:
- Merit-Based Recruitment: Conducting objective, transparent competitive examinations for appointments to All-India Services (IAS, IPS, IFoS) and Central Civil Services (Group A and Group B).
- Direct Selection & Interviews: Administering lateral entry and specialized recruitment interviews for scientific, technical, and specialized administrative roles.
- Advisory Functions: Advising the Central Government on recruitment rules (RRs), promotion suitability of state civil service officers to All-India cadres, and disciplinary appeals.
- Constitutional Independence: Commissioners and the Chairman are appointed by the President and enjoy tenure security to ensure impartiality from political influence.

General Eligibility Concept Across UPSC Exams
Because UPSC recruits across divergent sectors—from 18-year-old school leavers joining the military to specialized technical engineers—there is no universal eligibility rule:
- Nationality: Candidates for All-India Services (IAS, IPS) must be citizens of India. For other services and defence exams, subjects of Nepal, Bhutan, and eligible migrants may apply as per gazette rules.
- Academic Variance: Entry criteria span 12th pass (NDA), Bachelor's in any stream (CSE, CAPF), technical engineering degrees (ESE), to medical MBBS degrees (CMS).
- Age Parameters: Range from 16.5–19.5 years for NDA, 19–25 years for CDS, to 21–32 years for Civil Services.
- Physical Fitness: Civil services evaluate general medical fitness, whereas military (NDA/CDS) and paramilitary (CAPF) examinations enforce rigorous physical measurements and endurance trials.
How UPSC Recruitment Works
Each competitive examination adheres to a rigorous, structured pipeline:
Annual Calendar Notification

Online Application Submission (upsconline.nic.in via OTR)
↓
Stage 1: Preliminary Screening Examination (Objective)
↓
Stage 2: Main Examination (Subjective / Descriptive / Technical)
↓
Stage 3: Personality Test (Interview) / SSB / Physical Standards

Consolidated Final Merit List & Service Allocation- One-Time Registration (OTR): Candidates create a verified profile on the UPSC portal before filling examination-specific application forms.
- Multi-Stage Filtering: The commission uses high-standard objective screening (Prelims) to shortlist serious candidates for extensive written essay and technical papers (Mains).
- The Personality Test: Designed not to re-test factual memory, but to assess intellectual alertness, critical assimilation, balance of judgment, integrity, and leadership abilities.
Official Notification Importance
Candidates must never rely on hearsay or unofficial summaries for critical decisions. Every recruitment cycle is governed by its specific official notification published in the Employment News and on upsc.gov.in. The notification specifies the exact cut-off dates for age calculation, category certificates, reservation quotas, and examination centers.
