UPSC CDS Eligibility 2026 — Every Academy Has Different Rules
One of the most common mistakes CDS aspirants make is assuming a single eligibility standard applies to all four academies. It does not. IMA, INA, AFA, and OTA each have different educational requirements, age limits, and physical standards. Here is the complete academy-wise breakdown so you know exactly where you stand before applying.
Educational Qualification — Academy-Wise
| Academy | Required Qualification | Gender |
|---|---|---|
| IMA (Indian Military Academy) | Graduation in any discipline from a recognised university | Male only |
| INA (Naval Academy) | Engineering degree (BE/B.Tech) in any discipline | Male only |
| AFA (Air Force Academy) | Graduation in any discipline + Physics and Mathematics at 10+2 level | Male only |
| OTA (Officers Training Academy) | Graduation in any discipline from a recognised university | Male + Female |
Nationality and Domicile
The candidate must be a citizen of India. Subjects of Nepal, subjects of Bhutan, Tibetan refugees who came to India before 1 January 1962 with the intention of permanently settling, and persons of Indian origin who have migrated from specific countries (Pakistan, Burma, Sri Lanka, East African countries of Kenya, Uganda, Tanzania, Zambia, Malawi, Zaire, Ethiopia, and Vietnam) with the intention of permanently settling in India are also eligible — subject to the requisite certificate from the Government of India.
When You Are in the Final Year of Graduation
Candidates who are in the final year of graduation are eligible to apply for CDS. However, they must produce proof of passing the graduation examination (original degree or marksheet) at the time of SSB interview. If you are called for SSB but have not yet cleared your final year exams, you will not be permitted to appear. Plan your exam schedule accordingly if you are in your final semester.
What Disqualifies You — Common Reasons for Rejection
Based on patterns from past SSB and medical processes, here are the most common disqualifying factors:
- Colour blindness: Disqualifying for all three services. If you cannot distinguish red, green, and other standard colours, you will fail the medical regardless of which academy you applied for.
- Poor uncorrected vision (AFA): Any degree of myopia — even mild — disqualifies you from AFA. Spectacle wearers are not eligible for AFA flying branch. LASIK surgery is conditionally permitted but requires a waiting period and re-examination.
- Height below minimum: If you are below 157.5 cm (Army male), 162.5 cm (AFA), or 152 cm (OTA female), you cannot be commissioned regardless of written or SSB performance.
- Tattoos on visible skin: Tattoos on the face, neck, or hands are generally disqualifying. Tattoos on covered body areas are conditionally permitted — the specific policy for each service should be verified from the official notification.
- Flat feet (Pes Planus): May be disqualifying or conditionally acceptable depending on severity — assessed at medical.
- Marital status discrepancy: Declaring yourself unmarried while being married is grounds for permanent disqualification.
The INA Engineering Requirement — A Narrower Pool
INA (Naval Academy) is the only CDS academy that requires an engineering degree. This significantly narrows the applicant pool compared to IMA and OTA — but it also makes the competition among INA applicants more homogeneous. If you are a B.Tech graduate who also wants to apply for IMA and OTA, you can apply for all three in the same application form. Your written exam scores and SSB recommendation determine which academy you are ultimately allocated.
How to Prepare Your Application — Practical Checklist
- ✓ Check age eligibility for your preferred academy (INA has the narrowest window: 19–22 years)
- ✓ Verify Class 12 subjects if applying for AFA (Physics + Maths mandatory)
- ✓ Confirm graduation degree or attach proof of being in final year
- ✓ Check vision without glasses — if you wear spectacles, check your refractive error before applying for AFA
- ✓ Verify marital status requirement for your chosen academy
- ✓ Check the official UPSC CDS II 2026 notification at upsc.gov.in for exact cutoff dates and any updated physical standards
- ✓ Apply online at upsconline.nic.in before the deadline: 9 June 2026
CDS vs NDA — Two Routes to the Same Commission
The Indian Military Academy, Naval Academy, and Air Force Academy can be reached via two different UPSC exams: NDA (for Class 12 pass candidates, aged 16.5–19.5 years) and CDS (for graduates, aged 19–24 years). Both lead to the same commission. The differences:
| Parameter | NDA Route | CDS Route |
|---|---|---|
| Eligibility | Class 12 pass | Graduate |
| Age | 16.5–19.5 years | 19–25 years |
| Training duration | 4.5–5 years (NDA + Academy) | 1.5 years (IMA) / 4 years (AFA) |
| Degree from Academy | B.Sc. from JNU (NDA) | No separate degree |
| Commission age | ~21 years | ~23–25 years |
Application Process — Step by Step
The CDS application process is entirely online through UPSC's portal:
- Registration: Create a one-time account at upsconline.nic.in. Use a valid email and mobile number — all communication happens through this.
- Fill the form: Select which academies you want to apply for (you can choose all four). Enter personal details, educational qualification, and upload photo and signature in the specified format.
- Fee payment: ₹200 for General/OBC male candidates. SC/ST and female candidates are exempt. Payment via SBI net banking, Visa/Mastercard debit/credit card, or UPI.
- Submit and download: Download the completed application form PDF for your records. UPSC does not send printed admission cards — the e-admit card is downloaded from the portal 3 weeks before the exam.
Last date to apply for CDS II 2026: 9 June 2026. The exam is on 14 September 2026. Apply early — UPSC servers often slow down near the deadline.
Service Bond and Conditions After Joining
Unlike many government jobs, CDS officers do not sign a bond in the traditional sense at the time of application. However, after joining the academy and being commissioned as an officer, the following service conditions apply:
- Permanent Commission officers (IMA/INA/AFA): Expected to serve until retirement age (54–60 years depending on rank). Voluntary retirement is possible after 20 years of qualifying service with full pension. Early resignation before 20 years means forfeiting pension entitlement.
- Short Service Commission officers (OTA): Initial tenure of 10 years, extendable to 14 years. Application for release must be submitted 3 months in advance. No pension unless converted to PC after 14 years.
- Training period: Cadets who leave the academy mid-training are required to refund training costs incurred by the government — typically ₹1–5 lakh depending on how far into training they leave.
Medical Fitness — How to Prepare Before SSB
Several medical conditions can be corrected or improved before your medical examination if you know about them in advance:
- Weight/BMI: If you are outside the BMI 18.5–30 range, you have time to correct this before SSB. Both underweight and overweight are grounds for temporary rejection — you can be re-examined after 3–6 months.
- Dental issues: Cavities and missing teeth beyond a certain threshold are flagged in the medical. Get dental treatment done before your medical examination.
- Flat feet (Pes Planus): Mild flat feet may be conditionally cleared; severe cases are rejected. Cannot be corrected easily — check with a doctor before applying if you suspect this.
- Vision: If you have mild myopia and want to apply for AFA, LASIK surgery is an option but requires a minimum 6-month waiting period post-surgery before the medical. Plan accordingly. For Army and Navy, spectacle wearers within the permissible refractive error range are eligible.
The NDA route commissions you earlier (younger rank progression, earlier promotion, earlier pension eligibility). The CDS route is for those who missed NDA age or prefer to join after completing graduation. Both are equally respected within the armed forces.
Which Academy Should You Prioritise?
Your choice of academy should be based on your profile — not just preference:
- Apply for IMA if: You are a graduate (any stream), male, 19–24 years old, and want Army PC. IMA is the largest quota in CDS and has the broadest eligibility.
- Apply for INA if: You have a B.Tech degree. INA requires an engineering background. Navy service offers specialised roles in submarines, aviation, and surface warfare.
- Apply for AFA if: You have Physics + Maths at 12th, perfect uncorrected vision, and a strong aptitude for flying. AFA is the most competitive and the hardest to get into medically.
- Apply for OTA if: You are female, OR you are a male graduate who is 25 years old (past IMA age limit), OR you want Short Service Commission first with the option to convert to PC later.
You can mark multiple preferences in a single application — many candidates apply for all four and let their SSB recommendation and merit determine the final allocation.
Physical Fitness — What the GTO Actually Tests
During the SSB, the Group Testing Officer (GTO) tasks are physically demanding. You do not need to be an athlete, but you need a functional level of fitness. Specific activities during GTO tasks include:
- Individual Obstacles: 10 obstacles (rope climbing, vault, crawl under barbed wire, jump over structures) completed against time. Upper body strength and coordination are tested.
- Progressive Group Task (PGT): Team crosses a series of obstacles using planks, ropes, and barrels. Requires climbing and load-bearing.
- Half Group Task (HGT): Smaller team crosses obstacles — similar demands as PGT.
There is no formal minimum fitness requirement announced before SSB — but candidates who cannot complete basic physical tasks (rope climb, vaulting, sustained physical effort over 3–4 hours) are noticed by GTO assessors. A minimum 4-month physical preparation routine before SSB is strongly advisable: running 3–5 km daily, 20+ push-ups, 10+ chin-ups, and functional bodyweight exercises.
Important for AFA: You need Physics AND Mathematics specifically at the 10+2 (Class 12) level — not just at graduation. A B.Sc. in Physics is not enough if your 12th board did not have Maths. Check your Class 12 marksheet before applying for AFA.
Age Limits — Academy-Wise
| Academy | Age Range | Note |
|---|---|---|
| IMA | 19–24 years | As on 01 Jan of course commencement year |
| INA | 19–22 years | Strictest age limit — narrows the window |
| AFA | 20–24 years | Must have completed graduation |
| OTA (Men + Women) | 19–25 years | Widest age window |
There are no caste-based age relaxations for CDS — unlike most UPSC civil service exams. The age window is strict for all categories. No attempt limit is officially specified; you can appear as many times as your age permits.
Marital Status
- IMA / INA / AFA: Must be an unmarried male at the time of application and at the time of joining
- OTA: Open to unmarried men, unmarried women, issueless widows, and issueless divorcees (with requisite documentation)
Marrying during training is not permitted. Candidates who marry during training can be dismissed.
Physical Standards
| Parameter | Army — IMA/OTA (Male) | OTA (Female) | Navy — INA | Air Force — AFA |
|---|---|---|---|---|
| Min Height | 157.5 cm | 152 cm | 157 cm | 162.5 cm |
| Chest | 81 cm min, 5 cm expansion | — | 81 cm min, 5 cm expansion | 81 cm min, 5 cm expansion |
| Weight | BMI 18.5–30 | BMI 18.5–30 | BMI 18.5–30 | BMI 18.5–30 |
Vision Standards — AFA Is Strictest
Vision requirements differ significantly across services. The Air Force has the strictest eye standards because of the demands of flying.
| Service | Unaided Vision | Spectacles | Key Restriction |
|---|---|---|---|
| Army (IMA/OTA) | 6/6 better eye, 6/18 worse eye | Permitted within limits | Colour blindness disqualifying |
| Navy (INA) | 6/6 better eye, 6/12 worse eye | Permitted within limits | Colour blindness disqualifying |
| Air Force (AFA) | 6/6 in one eye, 6/9 in other | Not permitted | Nil myopia; max hypermetropia +2.0 D; Colour Perception CP-I mandatory |
If you wear spectacles habitually, you are not eligible for AFA — even if corrected vision is 6/6. LASIK surgery is allowed for Army and Navy with a waiting period, but AFA has its own specific LASIK rules that are worth checking in the official notification before you invest in surgery.
Women Eligibility — Only Via OTA
Women can only apply for CDS through OTA (Officers Training Academy, Chennai). IMA, INA, and AFA are currently open only to male candidates. OTA gives Short Service Commission (SSC) — an initial 10-year tenure, extendable to 14 years. After the 2020 Supreme Court order, women officers can apply for Permanent Commission (PC) after 14 years of service, giving them the same career track and pension as men who join via IMA.
