The Combined Defence Services (CDS) Examination is the main written route for graduates who want to join the Indian Military Academy (IMA), the Indian Naval Academy (INA), the Air Force Academy (AFA) or the Officers’ Training Academy (OTA). If you are targeting the first cycle of next year, the question that matters most right now is the CDS 1 exam date 2027 and how the rest of the schedule will fall into place around it. This guide sets out the dates UPSC has already scheduled, the official timeline of the CDS (I) 2026 and CDS (II) 2026 cycles for comparison, and a realistic, stage-wise plan from notification to joining the academy.
Status as on 11 November 2026: The CDS (I) 2027 notification has not been released yet. As per the UPSC Programme of Examinations (annual calendar) for 2027, the notification is scheduled for 2 December 2026, the last date to apply is 22 December 2026 and the written exam is scheduled for 11 April 2027. These are scheduled dates, and UPSC states that its calendar can change if circumstances require. Every other date in this article, such as the admit card, result and SSB interviews, is marked as expected and is based on the official dates of recent cycles. This page will be updated as soon as UPSC publishes the CDS (I) 2027 notice.

Has the CDS 1 2027 Notification Been Released?
No. As on 11 November 2026, the CDS (I) 2027 examination notice is not available on the UPSC website. The commission’s current exam notification list shows other 2027 examinations, and the CDS (I) 2027 notice is due on 2 December 2026 as per the calendar. Once it is published, it will confirm the exact application window, vacancies for each academy, course commencement months, eligibility and fee details.
Be careful with posts that quote final vacancy numbers or a confirmed admit card date for CDS 1 2027 at this stage. Until the official notice is out, no such figure is final.
Official Dates of Recent CDS Cycles
The best way to understand how CDS 1 2027 will run is to look at how UPSC actually conducted the last two cycles. The dates below are taken from the official UPSC examination pages and notices.
| Stage | CDS (I) 2026 (official) | CDS (II) 2026 (official) | CDS (I) 2027 |
|---|---|---|---|
| Notification | 10 December 2025 | 20 May 2026 | 2 December 2026 (scheduled) |
| Last date to apply | 30 December 2025, 6:00 PM | 11 June 2026, 6:00 PM (extended) | 22 December 2026 (scheduled) |
| Time table uploaded | 7 January 2026 | 10 August 2026 | Expected: January 2027 |
| e-Admit card | 2 April 2026 | 3 September 2026 | Expected: early April 2027 |
| Written exam | 12 April 2026 (Sunday) | 13 September 2026 (Sunday) | 11 April 2027 (Sunday, scheduled) |
| Written result (roll list) | 8 May 2026 | 19 October 2026 | Expected: May 2027 |
| Final result | 2 November 2026 | Awaited | Expected: late 2027 |
Three patterns stand out. First, the exam is always held on a Sunday. Second, the e-admit card came out ten days before the exam in both 2026 cycles. Third, the CDS (I) 2026 written result came 26 days after the exam, while the CDS (II) 2026 result took 36 days. For CDS 1 2027, this points to an admit card in the first week of April 2027 and a written result in May 2027.
CDS 1 2027 Application Process and Key Dates
Application Window
The application window for CDS (I) 2027 is scheduled to run from 2 December 2026 to 22 December 2026. In the CDS (I) 2026 cycle, the window was open from 10 December to 30 December 2025, and online applications could be filled up to 6:00 PM on the last day. The CDS (II) 2026 deadline was extended by two days, from 9 June to 11 June 2026, but you should never plan around an extension.
Where to Apply
Applications are submitted online only through UPSC’s online application portal. In recent cycles, candidates first completed a one-time registration and then filled the examination-specific form, choosing their academy preferences, exam centre and uploading the required documents.
Check Eligibility Before the Window Opens
Use the time before 2 December 2026 to check your eligibility, because UPSC does not allow changes to key details such as date of birth once the form is submitted. Each academy has its own age band and marital status rule, and the expected DOB windows for this cycle are explained in our guide to the CDS 1 age limit 2027. Educational eligibility is separate: a degree for IMA and OTA, an engineering degree for INA, and a degree with Physics and Mathematics at 10+2 level (or a B.E.) for AFA.
CDS 1 2027 Admit Card: Expected Timeline
As per the CDS (I) 2026 notice, eligible candidates are issued an e-Admit Card on the last working day of the week before the examination, and it is made available only on the UPSC website. It is not sent by post or email. In practice, the admit card was released on 2 April 2026 for the 12 April 2026 exam and on 3 September 2026 for the 13 September 2026 exam.
For CDS 1 2027, with the exam scheduled on 11 April 2027, the e-admit card is expected in the first week of April 2027. UPSC usually releases a detailed time table for the three papers a few months earlier, as it did on 7 January 2026 for the CDS (I) 2026 cycle.
- Download the e-admit card only from the official UPSC website.
- Check your name, photograph, roll number, centre and paper timings carefully.
- Carry a printout of the e-admit card and the original photo ID mentioned in it.
- Report any discrepancy to UPSC immediately, well before the exam day.
CDS 1 2027 Exam Day: Papers and Pattern
The CDS written exam is held on a single day. Candidates for IMA, INA and AFA write three papers, while candidates applying only for OTA write two. The pattern below is the one followed in the latest official CDS notices. It will be confirmed for 2027 in the CDS (I) 2027 notification.
| Course | Subject | Duration | Maximum Marks |
|---|---|---|---|
| IMA, INA and AFA | English | 2 hours | 100 |
| IMA, INA and AFA | General Knowledge | 2 hours | 100 |
| IMA, INA and AFA | Elementary Mathematics | 2 hours | 100 |
| OTA (SSC Men and Women) | English | 2 hours | 100 |
| OTA (SSC Men and Women) | General Knowledge | 2 hours | 100 |
All papers are objective type, and there is a penalty of one-third of the marks assigned to a question for each wrong answer. The SSB interview carries 300 marks for IMA, INA and AFA, and 200 marks for OTA. Because the exam is spread over most of the day, plan your food, water and travel so that fatigue does not affect the last paper.
What Happens After the CDS 1 2027 Exam
Written Result
UPSC first publishes a roll-number list of candidates who have qualified the written exam, followed by a list with names. For CDS (I) 2026, the roll list came on 8 May 2026 and the name list on 20 May 2026. On a similar timeline, the CDS 1 2027 written result is expected in May 2027.
SSB Interview
Qualified candidates are called for the Services Selection Board (SSB) interview, which tests intelligence and personality over a five-day process, including screening, psychological tests, group tasks and a personal interview. In the CDS (I) 2026 notice, candidates who qualified for IMA, INA and/or AFA were to be detailed for SSB in August to September 2026, while candidates who qualified for the SSC (OTA) course only were to be detailed in October to December 2026. A similar pattern is expected for 2027. AFA candidates also go through the Computer Pilot Selection System (CPSS).
Medical Examination and Final Merit List
Candidates recommended by the SSB undergo a medical examination. The final merit list is prepared on the basis of written marks plus SSB marks, separately for each academy. For CDS (I) 2026, the final result was declared on 2 November 2026, about seven months after the exam. The CDS 1 2027 final result can therefore be expected in the last quarter of 2027.
Course Commencement
In the CDS (I) 2026 cycle, the IMA, INA and AFA courses commence in January 2027 and the OTA courses in April 2027. If UPSC follows the same pattern, CDS (I) 2027 will feed courses starting in January 2028 for IMA, INA and AFA and April 2028 for OTA. These months are expected until the 2027 notice confirms them.
CDS 1 2027 Preparation Plan Around the Scheduled Dates
| Period | What to Do |
|---|---|
| Now to 1 December 2026 | Confirm eligibility, keep your Class 10 certificate, degree documents, photo ID and photographs ready, and start a structured study plan. |
| 2 to 22 December 2026 | Apply as early as possible after the notice is released; choose academy preferences carefully. |
| January to February 2027 | Complete the syllabus for English, General Knowledge and Elementary Mathematics; start sectional tests. |
| March 2027 | Full-length mock tests on the three-paper, same-day format; revise current affairs of the last 12 months. |
| Early April 2027 | Download the e-admit card, check the centre and timings, and focus on revision rather than new topics. |
| After 11 April 2027 | Start SSB preparation straight away so that you are ready when the written result is declared. |
Your academy choices affect both eligibility and preparation. If you are close to the upper or lower edge of an age band, check the exact range in our CDS age limit guide before deciding your preferences.
Important Points to Keep in Mind
- Apply only through UPSC’s official online application portal; no other website can submit your form.
- Do not wait for the last day. Server load is highest near the deadline, and an extension is never guaranteed.
- Your date of birth must match your Matriculation or Secondary School certificate, and it cannot be changed after submission.
- Choose academy preferences carefully, because the order of preference is used for allotment after the final result.
- Keep your registered email ID and mobile number active throughout the selection process.
- Read the CDS (I) 2027 notice in full once it is out, because vacancies, course dates and some rules can change from one cycle to the next.
