Moreover, it provides opportunity for entrance in Indian Army, Indian Navy and Indian Air Force. Once the cadet clears this examination, They need to undergo a training of three years in the Academy. This training is in sync with the graduation with BA/BSc or BCs (Computer Science) degree of Jawaharlal Nehru University.

Besides academic training, the candidates are also equipped with outdoor skills like drilling, physical training and games. In the first place, NDA always puts more stress on character building, esprit-de-corps, mental and physical flexibility and rigidness, leadership and a sense of observation.
