Is NDA SSB Different from CDS SSB Interview? – Complete Guide for 2026 Aspirants

Introduction to NDA & CDS SSB Interviews

The Services Selection Board (SSB) interview is the ultimate test for those who aspire to wear the prestigious uniform of the Indian Armed Forces. Whether you enter through NDA (National Defence Academy) after 12th standard or CDS (Combined Defence Services) after graduation, the SSB remains the gateway to becoming an officer.

But one common doubt persists among aspirants:
👉 Is NDA SSB different from CDS SSB?

The short answer is No – the procedure is the same.
However, the candidate profiles, maturity levels, and evaluation expectations differ significantly. This guide breaks down every aspect of the NDA SSB vs CDS SSB so that 2026 aspirants can prepare with clarity.

While both follow the same 5-day testing procedure, there are subtle differences in approach, candidate maturity, and preparation expectations. Let’s break it down in detail.

NDA SSB vs CDS SSB – The Eligibility Factor

NDA SSB Eligibility (Age & Qualification)

  • Age: 16.5 to 19.5 years

  • Education: Must have passed 12th standard (Physics & Maths required for Air Force and Navy).

  • Profile: Young candidates with minimal professional exposure, assessed more on potential than experience.

CDS SSB Eligibility (Age & Qualification)

  • Age: 19 to 25 years

  • Education: Graduate (final-year students can also apply).

  • Profile: Candidates are older, more educated, and expected to showcase maturity and leadership readiness.

Key takeaway: The eligibility difference shapes the evaluation lens. NDA candidates are judged on raw trainability, while CDS candidates are expected to demonstrate developed officer-like qualities (OLQs).

So structurally, there is no difference in the procedure.
