UPSC CDS (I): Exam Date, Notification & Latest Update

CDS (I) 2027 at a glance: who it recruits and what the job entails

The Combined Defence Services Examination (I) 2027 is conducted by the Union Public Service Commission to select candidates for permanent and short-service commissions in the Indian Army, Navy and Air Force. Successful candidates join the Indian Military Academy (Dehradun), Officers’ Training Academy (Chennai), Indian Naval Academy (Ezhimala) or Air Force Academy (Hyderabad). Officers posted through CDS serve in field, staff and instructional roles, with opportunities for higher technical and command courses. The career path includes promotions, specialised training and postings across India and abroad, subject to service requirements.

Three gates: prelims, mains and SSB interview

Preliminary examination

SSB interview

The final gate is a five-day assessment conducted by the Services Selection Board. The process includes screening tests, psychology evaluations, group tasks and a personal interview, culminating in a conference on the fifth day. The board looks for officer-like qualities—leadership, teamwork, communication and mental robustness. Candidates who treat the SSB as a conversation rather than an interrogation usually perform better than those who rehearse scripts.

Vacancy outlook and realistic odds

The number of vacancies for CDS (I) 2027 will be notified on 2 December 2026 and published on the UPSC website. Historically, the total vacancies have ranged between 300 and 400 across all academies, with the Indian Military Academy and Air Force Academy attracting the highest competition. The ratio of applicants to vacancies has varied from 8 : 1 to 12 : 1, meaning roughly one in ten candidates is shortlisted for mains. Because the prelims cut-off is normalised, even small differences in attempted questions can swing the result by several marks; candidates should therefore aim for a score comfortably above the cut-off.

Who qualifies—and who should look elsewhere

Eligibility for CDS (I) 2027 is set out in the official notification dated 2 December 2026. In broad terms, candidates must be graduates aged 20–24 (with service-specific relaxations) and hold Indian citizenship. Women candidates are eligible only for the Short Service Commission at the Officers’ Training Academy. Final-year students may apply provisionally. Candidates who do not meet the age, qualification or nationality criteria should consider other defence exams scheduled later in the year, such as CDS (II) or AFCAT.

What you need to study—and what you can safely ignore

The CDS (I) 2027 syllabus is prescribed in the notification dated 2 December 2026. Candidates should focus on breadth in GK and precision in English; depth comes from practice rather than from reading multiple reference books.

Orientation guide for first-time applicants

If you are new to defence exams, start by reading the official notification and the exam updates on OurEducation. Decide whether CDS fits your career goals: the training is rigorous, postings can be remote, and the initial years involve frequent transfers. Compare CDS with NDA and AFCAT—NDA is for school-leavers, AFCAT is for technical graduates, and CDS is primarily for graduate entrants into permanent or short-service commissions. If you are unsure, sit for a mock test on UPSC CDS mock tests on Examophobia to gauge your comfort with the pattern before committing time.

Common pitfalls that waste time and effort

• Assuming last year’s cut-off is this year’s target. Normalisation and vacancy changes make cut-offs volatile; aim for a safe margin instead.
• Over-studying obscure topics. CDS rewards breadth in GK and accuracy in English; deep dives into niche subjects rarely pay off.
• Treating SSB as a formality. The board evaluates officer-like qualities, not academic scores; rehearsed scripts rarely impress.
• Neglecting physical fitness. SSB’s pass-fail physical tests can eliminate candidates regardless of academic performance.
