The Union Public Service Commission (UPSC) has released the official answer keys for the Combined Defence Services Examination 1 2026 across all question sets on its portal, enabling approximately 1.5 lakh candidates to cross-verify their responses and estimate their provisional scores ahead of final result publication.
The CDS examination, one of India’s premier recruitment pathways for officer-level positions in the Army, Navy, and Air Force, was conducted on February 2, 2026. The release of answer keys marks a critical juncture in the selection process, allowing candidates the window to file objections against potentially disputed questions before final answer key publication—a standard practice that the UPSC has maintained for transparency and procedural fairness across major national examinations.
The availability of set-wise solutions is particularly significant given the competitive intensity of the CDS recruitment cycle. With thousands of aspirants competing for limited officer commissions, the answer key release serves as an immediate feedback mechanism. Candidates can now perform a detailed question-by-question analysis, identify weak areas, and prepare strategies for potential re-attempts or supplementary examinations. The provisional scoring window also creates clarity on merit thresholds, aiding candidate expectations about cutoff probabilities.
All set-wise answer keys are accessible on the official UPSC website (upsc.gov.in), where candidates can download PDF documents corresponding to their examination shift and subject papers. The examination consisted of English, General Knowledge, and Elementary Mathematics sections, with objective-type questions designed to assess cognitive aptitude and domain knowledge requisite for defence service commissions. The answer keys enumerate correct options for each question, enabling straightforward self-assessment.
Candidates dissatisfied with specific answer key determinations retain the right to lodge formal objections during the prescribed objection window, typically open for 48-72 hours from answer key publication. Such objections undergo expert review; should UPSC accept an objection as valid, the corresponding answer key is revised and final merit lists are recalculated. This procedural safeguard has historically addressed instances where multiple defensible answers existed for particular questions, or where question framing contained ambiguities.
The timing of answer key release reflects UPSC’s operational cadence for defence services recruitment—a process that directly feeds officer pipelines critical to military operations and institutional capacity. The examination’s competitive threshold remains stringent; historical cutoff data indicates that candidates securing 40-50 percent aggregate marks face inclusion difficulty, particularly in General Knowledge and Mathematics sections where conceptual depth and speed are equally valued. The answer key release thus crystallizes for the broader candidate pool the difficulty parameters and knowledge gaps that characterize this recruitment cycle.
Beyond individual candidate utility, the answer keys serve administrative documentation value. They establish official record of examination content and correctness determinations, essential for future candidate grievance redressal and institutional audit compliance. Looking ahead, candidates should monitor UPSC communications for the objection submission deadline, final answer key notification date, and result publication schedule. The final merit list and candidate interview call schedules typically follow within 6-8 weeks of answer key finalization, meaning successful candidates can anticipate next-stage notifications by late March or early April 2026.
