NDA Exam (National Defence Academy)
The NDA exam is one of the few routes that lets students begin officer training for the armed forces straight after Class 12. Selection goes well beyond a written test: the SSB interview and medical standards are just as important, so preparation needs to cover character, fitness and communication too.
- Conducted by
- Union Public Service Commission (UPSC), usually twice a year
- Stages
- Written exam → SSB interview → medical examination → merit list
- Leads to
- Officer training at NDA, followed by academy training for the chosen service
- Open to
- Unmarried men and women meeting age and education conditions
About the exam
The National Defence Academy trains cadets for all three services. Candidates selected through the NDA exam complete about three years of training at the academy, during which they also earn a degree, followed by further training at their service academy before commissioning as officers.
The written exam is conducted by UPSC. Candidates who qualify then attend a multi-day Services Selection Board (SSB) interview that assesses intelligence, personality, teamwork and officer-like qualities, followed by a medical examination.
