UPSC CDS 2025 I and II: Notifications and key dates
The UPSC Combined Defence Services Examination is a national-level recruitment process for graduates seeking entry to the Indian Military Academy, Indian Naval Academy, Air Force Academy and Officers’ Training Academy. The Union Public Service Commission conducts two written examinations each year, followed by selection stages managed by the Services Selection Board.
For candidates tracking the UPSC CDS 2025 I and II examination cycle, the notification release date, application deadline and written exam date are the most important milestones. These dates determine when applications must be submitted, when preparation should intensify and when candidates need to arrange travel to an allocated examination centre.
This guide is also useful for Indian citizens living in Australia, including applicants based in Sydney, Melbourne, Brisbane or Perth. Australian Eastern Standard Time is several hours ahead of Indian Standard Time, so an Indian deadline can effectively fall on the following morning in Australia.
What the CDS 2025 examination covers
The CDS examination is designed for graduate-level officer entry into India’s armed forces. CDS I and CDS II use broadly similar eligibility rules, written subjects and selection procedures, although the number of vacancies and academy preferences can change between notifications.
Candidates generally compete for the Indian Military Academy, Indian Naval Academy, Air Force Academy or Officers’ Training Academy. The written examination is followed by an SSB interview for shortlisted applicants, medical assessment and final merit preparation. The Air Force Academy may include additional requirements, such as physics and mathematics at school level.
UPSC notifications remain the controlling documents. They specify age limits, gender and marital-status conditions, educational qualifications, physical standards, fee rules, vacancy details and academy-specific requirements. A previous year’s eligibility should not be treated as automatic proof of eligibility for CDS 2025.
CDS I notification and examination dates
The CDS I 2025 notification was released by UPSC on 11 December 2024. The online application window closed on 31 December 2024, and the written examination was scheduled for 13 April 2025.
This cycle was relevant to applicants seeking an earlier route into the 2025–26 training intake. Candidates needed to complete the online form, upload or enter the required information correctly and preserve their application details. An incorrect academy preference, spelling error or mismatch in personal information can create difficulties later in the recruitment process.
Applicants living in Australia needed to account for the time difference when submitting the form. A deadline displayed in Indian Standard Time should be checked carefully rather than left until a usual Australian evening routine. Sydney and Melbourne candidates may also need to plan for an international trip if the assigned centre is in India.
CDS II notification and examination dates
The CDS II 2025 notification was scheduled for release on 28 May 2025. The application deadline was 17 June 2025, while the written examination was scheduled for 14 September 2025. These dates form the central timetable for the second Combined Defence Services recruitment cycle of the year.
CDS II can provide another opportunity for eligible graduates who missed CDS I, did not apply in time or want to improve their preparation before entering the selection process. However, the later examination does not remove the need to satisfy the relevant age and qualification conditions on the dates specified by UPSC.
A notification may also include instructions about application corrections, fee payment, photograph or signature requirements and examination-city preferences. Candidates should read the complete PDF rather than relying on short social media summaries. Any later revision issued by UPSC takes priority over a secondary calendar.
Eligibility and application checkpoints
Applicants normally need a recognised university degree for most CDS entries. Engineering qualifications can be relevant to the Indian Naval Academy and Air Force Academy, while the Air Force route may require science subjects at school level. Final-year students may be permitted to apply under specified conditions, but they must produce proof of passing when required.
Age requirements differ by academy and are expressed through date-of-birth ranges in the notification. This is particularly important because the limits can vary between CDS I and CDS II. Applicants should compare their birth date with the exact range printed in the relevant 2025 notice instead of using a general age calculator.
The online form should be completed through the official UPSC application system. Before paying any fee, candidates should check their name, date of birth, nationality, educational record, category information, contact details and academy preferences. Keeping a PDF copy of the submitted form and payment receipt is a sensible record-keeping habit.
Written exam pattern and centre planning
For the Indian Military Academy, Indian Naval Academy and Air Force Academy, the written examination generally includes English, General Knowledge and Elementary Mathematics. Each paper is commonly set for 100 marks, with objective questions and negative marking. The Officers’ Training Academy written test normally includes English and General Knowledge.
The written result does not itself guarantee appointment. Successful candidates are called for the SSB interview, which assesses officer potential through intelligence testing, psychological exercises, group tasks and personal interviews. Medical fitness and the final merit list remain essential parts of the recruitment process.
Australian applicants should budget for flights, accommodation and local transport in India well before the SSB stage. A candidate travelling from Perth may face a different route and cost from someone flying from Melbourne or Sydney. Time-zone planning also matters when checking results or downloading an admit card, because a notice released during Indian business hours may arrive during the Australian afternoon or evening.
Tracking admit cards, results and official notices
A reliable tracking routine helps candidates follow every stage after submitting the form. The admit card is usually released before the written exam, while answer keys, written results, SSB updates and final merit lists may appear at separate times. The UPSC admit card updates section can help candidates monitor this stage alongside official UPSC announcements.
Candidates should use the registration number, roll number and date of birth exactly as requested when checking a result or downloading a document. Saving files to a secure cloud folder can be useful for Australians who move between home, university and work, but personal details should not be uploaded to unverified public platforms.
Useful tracking habits include:
- Add the notification, application and examination dates to an Australian calendar in both IST and local time.
- Check the official UPSC website and recruitment notices rather than relying only on messaging groups.
- Keep the submitted application, fee receipt, admit card and result PDF in one labelled folder.
- Confirm the examination city before booking non-refundable flights or accommodation.
- Treat requests for unusual payments or personal documents as possible scams and verify the source first.
Comparing the two 2025 CDS cycles
The two examinations follow a similar structure, but their calendars are separate. CDS I applications opened in late 2024 for an April 2025 written test, while CDS II applications opened in mid-2025 for a September examination. Candidates should always match their preparation and eligibility review to the correct cycle.
For Australians, consumer protection and privacy habits are useful when using online recruitment services. The Australian Consumer Law does not turn a private information website into UPSC, and no third-party portal can issue an official admit card or guarantee selection. Applicants should also avoid sharing identity documents casually and review privacy information before submitting personal data.
| Recruitment cycle | Notification date | Application deadline | Written examination |
|---|---|---|---|
| CDS I 2025 | 11 December 2024 | 31 December 2024 | 13 April 2025 |
| CDS II 2025 | 28 May 2025 | 17 June 2025 | 14 September 2025 |
The dates above should be read with the relevant UPSC notification and any later corrigendum. A candidate’s next practical step is to confirm eligibility, preserve the official application record and monitor the admit card and result stages through dependable recruitment news sources. For additional study-related material, an exam preparation resource may offer broader educational reading, but official UPSC notices remain authoritative for CDS requirements and dates.
Track the CDS 2025 timetable carefully, prepare for the written papers well before the application deadline and keep every recruitment document accessible. Regularly checking verified admit card, answer key, result and merit-list updates can prevent missed deadlines during the journey from application to defence academy selection.
