SSB Interview Eligibility & Age Limit (NDA, CDS, AFCAT)

Eligibility for the SSB interview is set by the specific entry scheme you apply through — NDA, CDS, AFCAT, TES, TGC, or direct Short Service Commission entries — and covers age, educational qualification, nationality, marital status (for some entries), and physical standards. There is no separate eligibility criterion for the SSB stage itself beyond clearing the preceding written exam or screening for that entry; if you qualify for the exam and are shortlisted, you are eligible to appear at SSB.

Age brackets, permitted educational streams, and marital status rules are revised across notification cycles, so treat the comparison below as a general orientation and always verify exact current figures against the official notification for your specific intake before applying.

General eligibility principles across entries

Regardless of which entry you apply through, a few principles hold broadly:

• You must meet the age bracket specified for that entry at the time of a specific cutoff date mentioned in the notification, not at the time you apply.
• You must hold (or be pursuing, for some entries like NDA) the educational qualification specified — this varies significantly by entry and by the specific service/branch.
• Nationality and other statutory eligibility conditions (Indian citizenship, or specified categories of other nationals) apply as per the notification.
• Marital status restrictions apply to some entries at the time of joining training, even if not at the time of application.
• Meeting exam and age eligibility does not guarantee an SSB call; that also depends on your rank in the written exam or shortlisting process.

Eligibility comparison across major entries (general orientation)

This table is indicative only. Age brackets, exact qualifying percentages, and permitted degree streams change across notification cycles — always confirm exact figures from the current official notification (UPSC for NDA/CDS, Indian Air Force for AFCAT, Indian Army/Navy recruitment portals for technical and direct entries) before applying.

Physical and medical eligibility

Beyond age and education, candidates must meet minimum physical standards (height, weight proportional to height, and vision standards vary by entry and branch, with some flying branches having stricter vision and anthropometric criteria) and pass a medical examination after being recommended at SSB. These standards are entry- and branch-specific and are detailed in each notification's medical standards annexure — refer to the guide linked below and the official notification for specifics rather than a generic figure.

Attempt limits

Some entries cap the number of attempts within a candidate's eligible age window (particularly relevant for NDA and CDS, since candidates can usually reattempt in the next cycle if still within the age bracket), while others are simply bound by the age bracket itself rather than a numeric attempt cap. Repeaters should check both the age eligibility and any attempt-specific conditions mentioned in the current notification.

Where to verify current eligibility

Always cross-check final eligibility details directly against:

• UPSC official notification for NDA & NA and CDS
• Indian Air Force official recruitment website for AFCAT
• Indian Army and Indian Navy official recruitment portals for TES, TGC, and direct SSC entries

Since these figures are revised periodically, relying on a single older source (including this guide) for exact cutoffs can lead to avoidable disqualification.

Age Calculation: A Frequent Source of Confusion

Age eligibility is calculated as of a specific cutoff date stated in each notification, not the date you submit your application or the date you sit for the exam. Candidates sometimes miscalculate their eligibility by using their age on the application date instead of the notified cutoff date, or by miscounting inclusive/exclusive date ranges. Read the exact wording in the notification ("not below X years and not above Y years as on [date]") carefully, and when in doubt, calculate conservatively and verify with the recruiting authority rather than assuming borderline eligibility will be accepted.

Educational Qualification Nuances Worth Checking Carefully

Beyond the broad "10+2" or "graduate" labels, several entries specify additional detail that is easy to miss — minimum aggregate percentage in specific subjects, a requirement that a degree be from a UGC-recognised university, or that certain technical entries require specific engineering disciplines rather than any engineering degree. Candidates in their final year of graduation are often eligible to apply provisionally for some entries, subject to producing proof of having passed by a specified date — confirm this provisional-eligibility clause for your specific entry rather than assuming it exists or does not.

Reservation and Category-Based Eligibility

Age relaxation and other eligibility relaxations for reserved categories (SC/ST, OBC, and other categories as applicable under government policy) apply to several entries, with the exact relaxation period specified in each notification. These provisions are entry-specific and subject to standard government reservation policy; check the relevant clause in your specific notification for the precise relaxation applicable to your category rather than assuming a blanket rule across all entries.

What Happens If You Are Found Ineligible After Selection

Eligibility is typically verified at multiple stages — at the time of written exam registration, again during document verification before or after SSB, and finally before joining the training academy. If a discrepancy in age, education, or other eligibility criteria is discovered at any stage, even after an SSB recommendation, it can lead to disqualification at that later stage. This is why accuracy on your original application form and PIQ, consistent with your original certificates, matters throughout the process and not just at the point of applying.
