CDS

CDS is the graduate-level route into the armed forces — the Indian Military Academy, Naval Academy, Air Force Academy and Officers' Training Academy. It is the natural next step for a defence aspirant who begins their groundwork at school and continues it through college.

Who can appear

Graduates, or final-year students, who meet the age and academy-specific conditions (the Air Force and Naval academies require an engineering or Physics/Maths background). Like the NDA, it is conducted by the UPSC twice a year and is followed by the SSB interview.

ℹ️

Selection follows the same written-exam-plus-SSB-interview process as the NDA, and is similarly competitive — which is why the groundwork for it is worth starting at school, not left until college.
