SSC adopts equipercentile method for multi-shift exam normalisation to ensure fairness

The change, effective immediately, seeks to neutralise discrepancies arising from varying shift difficulties and to align candidates’ performance relative to their peers.

Previously, the SSC’s normalisation relied on a blend of top scores, average marks, and score dispersion across shifts to adjust raw scores. While this approach aimed to compensate for tougher question sets, critics argued that statistical averages could still disadvantage candidates in particularly challenging windows. After an extensive review, the Commission opted for the equipercentile technique, which compares candidates by their percentile ranks within each shift rather than absolute scores.

Under the new framework, a candidate who outperforms 80 percent of test-takers in the morning session will be equated with a candidate who secures the 80th percentile in the afternoon session, regardless of raw score differentials. “By assessing candidates relative to their immediate cohort, we ensure equitable treatment across all exam sittings,” the SSC stated, reaffirming its commitment to improving evaluation processes and upholding examination sanctity.

The shift comes on the heels of protests and allegations of irregularities in recent SSC examinations, with aspirants and coaching institutions citing technical glitches and operational lapses. In response, the Commission has tightened its vigilance, warning against the discussion, analysis, or circulation of question papers under the Public Examinations (Prevention of Unfair Means) Act, 2024. Breaches of this act are classified as cognisable, non-bailable, and non-compoundable offenses, carrying stringent legal consequences.

Further, candidates appearing for forthcoming exams—including the SSC Combined Graduate Level (CGL) tests beginning September 12 have been cautioned against any attempt to engage in unfair means. Violators face severe administrative actions, such as cancellation of candidature and debarment from current and future SSC examinations, SSC said. Through these measures, the Commission aims to restore confidence among stakeholders and maintain the integrity of India’s premier recruitment platform.
