The CDS 1 2027 eligibility criteria determine whether candidates can apply for the UPSC Combined Defence Services Examination to join the Indian Military Academy (IMA), Indian Naval Academy (INA), Air Force Academy (AFA), or Officers Training Academy (OTA). Before submitting the application form, aspirants must check the age limit, educational qualification, nationality, marital status, and other conditions applicable to their preferred academy.

The eligibility requirements are not identical for every academy. For example, IMA and OTA require a recognised university degree, INA requires an engineering degree, and AFA has specific educational requirements involving Physics and Mathematics at the 10+2 level or an engineering degree.

CDS 1 2027 Eligibility Criteria at a Glance

CDS 1 2027 Age Limit

The CDS 1 2027 age limit differs according to the academy selected by the candidate. UPSC generally specifies eligibility through exact dates of birth rather than relying only on a general age range.

The following ranges are indicative projections based on the pattern of previous CDS examination cycles. They are not confirmed official CDS 1 2027 date-of-birth limits.

Candidates must use the dates printed in the CDS 1 2027 notification to determine their actual eligibility. The academy's course commencement date and UPSC's specified conditions also matter.

Age Limit for Indian Military Academy (IMA)

Candidates applying for IMA must satisfy the prescribed age requirements and the applicable marital-status conditions. Under the established rules, IMA is open to eligible unmarried male candidates.

Applicants should verify their date of birth against the official CDS 1 2027 notification before selecting IMA as a preference.

Age Limit for Indian Naval Academy (INA)

INA applicants must meet the academy's age requirements and possess the prescribed engineering qualification. The established entry conditions require unmarried male candidates.

Candidates should check both the age window and educational requirements before applying.

Age Limit for Air Force Academy (AFA)

The standard age range for AFA is generally 20–24 years, subject to the official date-of-birth conditions. Eligible candidates holding a valid and current Commercial Pilot Licence issued by the Directorate General of Civil Aviation (DGCA), India, may receive an upper-age extension up to 26 years under the prescribed conditions.

The age extension is not automatic for every candidate. Applicants must satisfy the applicable licence requirements and verify the official notification.

Age Limit for Officers' Training Academy (OTA)

OTA has separate eligibility provisions for its men's and women's courses. The general age range is approximately 19-25 years, but the official date-of-birth window determines eligibility.

Candidates should also check the specific marital-status conditions for the course they intend to select.

CDS 1 2027 Educational Qualification

The CDS educational qualification depends on the academy for which the candidate is applying. Candidates must hold the required degree from a recognised university or institution, or meet the permitted final-year conditions.

Educational Qualification for IMA

Candidates applying for the Indian Military Academy must possess a degree from a recognised university or an equivalent qualification.

Graduates from recognised streams such as BA, BSc, BCom and other eligible degree programmes may apply, subject to the remaining conditions. Candidates in the final year of their degree may also be eligible under the applicable UPSC rules.

Educational Qualification for INA

Candidates applying for the Indian Naval Academy must possess a degree in Engineering from a recognised university or institution, as prescribed in the notification.

A general graduation degree without the required engineering qualification does not ordinarily satisfy the INA educational requirement.

Educational Qualification for AFA

Candidates applying for the Air Force Academy must satisfy one of the prescribed educational routes:

• A degree from a recognised university with Physics and Mathematics at the 10+2 level.
• A Bachelor of Engineering degree.

Candidates must verify the detailed requirements in the official notification. Having a degree alone does not automatically establish AFA eligibility if the required subject conditions are not met.

Educational Qualification for OTA

Candidates applying for the Officers Training Academy must possess a degree from a recognised university or an equivalent qualification.

Graduates from different academic streams may apply, subject to the prescribed age, marital status, and other conditions.

Can Final-Year Students Apply for CDS 1 2027?

Yes, candidates studying in the final year or final semester of their degree may apply if they satisfy the conditions specified in the applicable UPSC notification.

However, applying as a final-year student does not mean that the degree requirement is waived. Candidates must submit proof of passing the degree examination by the deadline prescribed for their academy.

Before applying, final-year students should check:

• Whether their course and university meet the requirements.
• The deadline for submitting proof of graduation.
• Whether they have any pending examinations or results.
• The documents required by UPSC or the relevant academy.
• Whether the proof-submission deadline differs between academies.

Failure to submit the required proof by the prescribed deadline can lead to cancellation of candidature. Candidates should consult the CDS 1 2027 notification for the exact deadlines rather than relying on dates from an earlier examination.

CDS 1 2027 Nationality Criteria

The nationality conditions for CDS are prescribed by UPSC. Under the established rules, a candidate must belong to one of the eligible categories below:

• A citizen of India.
• A subject of Nepal.
• A person of Indian origin who has migrated from the countries specified in the notification with the intention of permanently settling in India.

The listed migration categories have historically included Pakistan, Burma, Sri Lanka, certain East African countries and Vietnam, subject to the exact terms in the applicable notice.

Candidates who are not Indian citizens may need to provide a certificate of eligibility issued by the Government of India. The notification also specifies exceptions, including the applicable provision for Gorkha subjects of Nepal.

Applicants should carefully read the nationality section of the official notice and confirm whether they need a certificate or other documentation.

CDS 1 2027 Marital Status Rules

The CDS marital-status requirements vary by academy and course. Candidates should not assume that the same rules apply to IMA, INA, AFA and OTA.

Marital Status for IMA and INA

The established rules require candidates applying to IMA and INA to be unmarried men who satisfy the prescribed eligibility conditions. Applicants should also review the restrictions relating to marriage during training.

Marital Status for AFA

Candidates below 25 years of age must generally be unmarried. 

Eligible married candidates aged 25 or above may apply under the applicable provisions, but restrictions apply during training. These may include restrictions on married accommodation and living with family outside the academy premises.

Candidates must verify the precise terms in the relevant notification.

Marital Status for OTA Men

Under the established rules, the OTA men's course is open to eligible unmarried male candidates. Male divorcees and widowers are not automatically treated as unmarried for CDS eligibility.

Applicants should check the exact course conditions before submitting their forms.

Marital Status for OTA Women

Eligible women may apply under the prescribed OTA women's course conditions. These include unmarried women and certain issueless widows or issueless divorcees who have not remarried and meet the documentation requirements.

Candidates should check the official notice for the applicable definitions and supporting documents.

Is There Any Age Relaxation in CDS 1 2027?

Under the established CDS eligibility rules, there is generally no category-based age relaxation for candidates belonging to SC, ST, OBC, EWS or other categories.

Candidates must fall within the date-of-birth window specified for their academy. Do not assume that a relaxation available in another recruitment examination also applies to CDS.

AFA's provision for certain eligible Commercial Pilot Licence holders is a specific academy-related age provision, not a general category-based relaxation.

CDS 1 2027 Physical and Medical Standards

Meeting the educational and age requirements does not guarantee final eligibility. Candidates must also meet the prescribed physical and medical standards for their respective services and academies.

Medical assessment may consider factors such as general health, vision, hearing, physical measurements and other service-specific requirements. The standards can differ depending on the entry.

Candidates should:

• Read the medical standards in the official notification.
• Review the applicable service-specific requirements.
• Seek qualified medical advice if they have concerns about their fitness.
• Avoid relying on unofficial claims about automatic exemptions.
• Check the requirements for their preferred academy before applying.

Final admission is subject to the prescribed selection process, medical fitness and other applicable conditions.

CDS 1 2027 Eligibility: Important Documents

Candidates should prepare the relevant information and documents before filling in the online application form. The exact document requirements must be checked in the official notification and application instructions.

Commonly relevant records include:

• Matriculation or secondary school certificate for date-of-birth proof.
• Graduation certificate or degree-related records, where applicable.
• Final-year or final-semester academic details, if applying provisionally.
• Engineering qualification documents for INA candidates.
• Educational records establishing the required Physics and Mathematics subjects for AFA, where applicable.
• Nationality or certificate-of-eligibility documents, if required.
• Commercial Pilot Licence details for eligible AFA applicants seeking the relevant age provision.
• Other certificates or declarations required by UPSC.

The date of birth should match the accepted school certificate or other document specifically permitted under UPSC rules. Candidates should not enter an estimated date or assume that it can be changed later.

How to Check CDS 1 2027 Eligibility Before Applying

Follow these steps to check your eligibility:

1. Visit the official UPSC website.
2. Open the examination notifications section.
