Do different UPSC interview boards give significantly different marks — is there board-wise data?

UPSC does not publish board-wise marks data. The Commission does not release a breakdown showing average marks awarded by each individual board, so direct board-to-board comparison by candidates or researchers is not possible from official sources.

What UPSC Confirms: Moderation Exists

UPSC officially confirms that marks moderation is applied across boards to maintain uniformity. The Ministry of Personnel stated this in Parliament in December 2025. The purpose is to ensure no candidate is systematically advantaged or disadvantaged based on the particular board they appeared before. The detailed methodology of this moderation is not published.

What Independent Research Has Found: Category-Correlated Variation

While board-wise data is unavailable, researchers and journalists have examined whether interview marks vary by social category — a related and more tractable question.

The Print's Analysis (CSE 2020 data):

The Print published an analysis of UPSC CSE 2020 data comparing written marks and interview marks across categories. Key findings:

The analysis, attributed to researcher Nethrapal and covered by The Print, found that General category candidates who score higher in written exams also score higher in interviews (statistically significant positive correlation), while SC, ST, and EWS candidates who score higher in written exams do not see a corresponding increase in interview marks — and may actually receive relatively lower interview scores.

UPSC's Official Response

UPSC has consistently rejected the inference of bias. Its position:

• The board does not know a candidate's category — it is withheld as part of the randomisation and anti-bias protocol
• Interview assessment is holistic and personality-based, not written-marks-linked
• Any correlation between category and interview marks reflects factors in the holistic personality assessment, not discriminatory intent

A PIB press release responding to a Parliament question on discrimination in UPSC interviews (PRID 2198899) stated that the personality test system "leaves no scope for discrimination or bias" given the structural safeguards in place.

What Academic Research Says: Structured vs. Unstructured Assessments

The broader literature on interview assessment (not UPSC-specific) is relevant:

• Structured interviews (standardised questions, fixed rubrics, multiple raters, recorded for review) consistently show lower evaluator bias and higher predictive validity than unstructured ones
• Unstructured personality assessments — where evaluators use holistic judgment — are more susceptible to affinity bias, cultural familiarity bias, and unconscious stereotyping
• UPSC's Personality Test is closer to the unstructured end: questions vary by board, there is no fixed rubric, and assessments are not recorded

This does not prove bias in UPSC's case, but it explains why the concern is structurally plausible and why reform proposals have emerged.

Proposed Reforms and UPSC's Position

UPSC's 2026 transparency reforms focused on the written examination (provisional answer key release for Prelims, QPRep portal for objections) rather than on interview process changes.

For Candidates: Practical Takeaway

1. UPSC cannot guarantee that all boards give identical marks — moderation reduces but does not eliminate inter-board variation
2. Your category and written marks are withheld from the board — what they see is only your DAF
3. The single most powerful thing in your control is how you come across as a person: composed, curious, honest, and analytically grounded
4. The debate about structural bias is legitimate and ongoing — candidates should be aware of it, but preparing differently based on their category is neither possible nor productive given the current system
