On October 1, 1926, India's first Public Service Commission was established. Created during the colonial period, it was initially an advisory institution operating within the administrative framework of British India.
A century later, the institution is known as the Union Public Service Commission, or UPSC, a constitutional body whose framework is defined by Articles 315 to 323 of the Constitution of India.
Editorial Insight
Key Highlights
Important points readers should notice.
Issue/Event: UPSC completes 100 years on October 1, 2026.
Location: New Delhi.
Authority/Organisation: Union Public Service Commission.
Action Taken: The centenary year has been used to examine recruitment, examination technology, transparency and the future of public services.
Impact: UPSC has evolved from a colonial-era commission into a constitutional institution handling examinations, recruitment-related functions and personnel matters at national scale.
The transformation between these two points is more than an institutional timeline. It reflects the changing nature of the Indian state itself — from a colonial administration with limited Indian participation to a constitutional democracy in which millions of citizens compete for positions in public administration.
According to government data released during the UPSC centenary year, applications across examinations and recruitment by selection handled by the Commission increased from 42,727 in 1950-51 to 45,10,044 in 2022-23.
The Civil Services Examination illustrates the scale even more clearly.
Editorial Analysis
Why This Matters
The UPSC centenary provides a useful window into the evolution of India's public administration. Over 100 years, the institution has moved through three very different phases: colonial administration, constitutional nation-building and the technology-driven governance environment of the 21st century. The numbers illustrate the scale of change, while developments in women's participation, social representation, language access and digital examination systems show how the recruitment process has adapted alongside Indian society. The central challenge for the coming decades will be maintaining a credible balance between merit, accessibility, transparency, security and changing administrative requirements.
For CSE 2025, 9,37,876 candidates applied for the Preliminary Examination. Of these, 5,76,793 appeared, 14,161 qualified for the Main Examination, 2,736 reached the Personality Test and 958 candidates were finally recommended.
The figures demonstrate how the examination has become one of India's most competitive public recruitment processes.
But the story of UPSC is not simply about competition. It is also about how recruitment has adapted to changes in India's social composition, constitutional framework, technology and expectations of transparency.
From the Colonial Commission to a Constitutional Institution
The establishment of the Public Service Commission in 1926 followed decades of debate around recruitment to India's higher administrative services.
The institution later became the Federal Public Service Commission in 1937. After India became a republic and the Constitution came into force in 1950, it became the Union Public Service Commission.
The constitutional transition fundamentally altered its position.
Articles 315 to 323 establish the framework for Public Service Commissions, covering their constitution, appointment and tenure of members, functions, finances and reporting responsibilities.
Article 320 provides for functions connected with examinations for appointments to Union services and other recruitment-related matters.
This constitutional foundation distinguishes UPSC from an ordinary recruitment agency. Its role is connected to the functioning of the public administration itself.
The Scale of Competition Has Changed
The expansion of India's population, education system and middle class has dramatically increased the number of people seeking government employment.
The growth in UPSC applications captures part of this transformation.
In 1950-51, applications across examinations and recruitment by selection stood at 42,727. By 2022-23, the figure had crossed 45 lakh.
The Commission's examination infrastructure has expanded alongside this demand. According to government data, the number of examination centres increased from eight in 1950 to 86 by 2026.
This is not simply a story of bigger examinations. It reflects the increasing geographical reach of India's competitive recruitment system.
CSE Shows How Narrow the Final Selection Has Become
The Civil Services Examination demonstrates the gap between demand and available positions.
In CSE 2025, nearly 9.38 lakh candidates applied for the Preliminary Examination, while 958 candidates were ultimately recommended.
This multi-stage structure is designed to progressively reduce the candidate pool through Preliminary Examination, Main Examination and Personality Test stages.
The nature of assessment is also becoming an important question.
As coaching systems, online learning platforms and artificial intelligence make prepared information increasingly accessible, the ability to test memorisation alone becomes less sufficient.
During centenary discussions, UPSC Chairman Dr. Ajay Kumar highlighted the importance of assessing reasoning, spontaneous thinking and judgement under ambiguity.
That direction reflects a broader challenge for modern public-service recruitment: administrators are increasingly expected to deal with situations for which there may be no standard textbook answer.
The Social Composition Has Also Changed
The people entering India's civil services today do not represent the same social composition as those entering the system in its early decades.
Government data released for the centenary shows a significant increase in women's participation.
In the 1952 Civil Services Examination, women accounted for 3 of the 83 recommended candidates. In CSE 2025, 299 of the 958 recommended candidates were women.
Representation of Scheduled Caste and Scheduled Tribe candidates has also increased over the decades.
SC recommendations in the Civil Services Examination rose from nine in 1955 to 158 in 2025, while ST recommendations increased from two in 1956-57 to 73 in 2025. Persons with benchmark disabilities also recorded an increase in representation, from three recommended candidates in 2002 to 42 in 2025.
These figures do not mean that questions around equal access have disappeared. They do, however, show how India's public recruitment system has become socially broader over time.
Language Became Part of the Access Question
Language has been another important part of this evolution.
The centenary material records that in 1970-71, UPSC informed the government that the Personality Test could be conducted only in English.
The position subsequently changed. From 1980-81, candidates have been permitted to answer in an Indian language, with interpretation arrangements where necessary.
The change is significant in a country where administrative work extends across numerous linguistic regions.
It also reflects a broader transition from the linguistic structures inherited from colonial administration towards a recruitment system operating within India's multilingual constitutional framework.
Technology Is Changing the Examination Process
The next major phase of UPSC's evolution is technological.
The Commission has introduced digital processes in several areas of examination administration, including e-admit cards and identity verification.
In 2025, AI-based facial authentication was piloted at selected centres for NDA & NA (II) and CDS (II) examinations.
The system was subsequently implemented at scale for the Civil Services Preliminary Examination on May 24, 2026, covering approximately 5.5 lakh candidates. Government information said facial authentication using invigilators' mobile phones took approximately six to eight seconds per candidate.
Technology can potentially reduce impersonation and strengthen examination security, but it also introduces new responsibilities involving data protection, system reliability and candidate confidence.
For an institution dealing with hundreds of thousands of candidates in a single examination cycle, a technical failure can become an administrative problem at national scale.
That makes cybersecurity and digital reliability increasingly important to the credibility of the examination system.
Transparency Is Evolving Too
The question of transparency has also received greater attention.
Following a Supreme Court judgment, UPSC formulated guidelines for releasing provisional answer keys after the Preliminary Examination. The government said the system would begin with the 2026 Civil Services Preliminary Examination and apply to structured examinations conducted by the Commission.
Marks for the Preliminary Examination are to be released after the final result.
The development illustrates an important principle in competitive examinations: transparency does not necessarily mean exposing every process while an examination is underway.
It can instead involve clearly defined rules, predictable procedures, appropriate disclosure and mechanisms through which candidates can understand how the process operates.
UPSC Is More Than the IAS Examination
Public discussion often uses “UPSC” and “IAS examination” almost interchangeably.
Institutionally, however, the Commission's responsibilities are considerably wider.
UPSC conducts multiple examinations and undertakes recruitment-related functions involving various Union services. It also provides advice concerning recruitment rules, promotions, induction into the All India Services and disciplinary matters.
During 2023-24, the Commission processed records relating to 24,581 officers for promotion, while 532 officers were inducted into the All India Services.
This makes UPSC part of a wider public-service personnel system rather than simply an examination authority.
What Does the Next Century Look Like?
The most important question surrounding UPSC at 100 is not whether the institution should remain unchanged.
It is how much it needs to adapt while protecting the principles that make competitive recruitment credible.
The next century is likely to be shaped by several pressures.
Artificial intelligence will change how candidates prepare and how examination authorities detect malpractice.
Digital administration will make secure identity verification and cybersecurity increasingly important.
Changing public administration will require officers to understand technology, climate risks, economic transitions, data systems, geopolitics and complex social challenges.
Access and inclusion will remain important as candidates increasingly come from different regions, languages and socioeconomic backgrounds.
And public trust will remain central because the legitimacy of a competitive examination depends not only on the result, but also on confidence in the process.
From Memorisation to Judgement
One of the biggest long-term questions may concern what the examination actually needs to measure.
Traditional competitive examinations necessarily test knowledge. But modern governance increasingly requires decision-making in situations where information may be incomplete, contradictory or rapidly changing.
A district administrator responding to a natural disaster, a regulator dealing with emerging technology or a policymaker handling a public-health emergency cannot rely entirely on predetermined answers.
This makes judgement, reasoning, communication and ethical decision-making increasingly relevant to the question of future recruitment.
UPSC's centenary discussions around reasoning and judgement suggest that this question is already part of the institution's future-oriented conversation.
