What is the NDA Exam?
The National Defence Academy (NDA) is the Joint Services academy of the Indian Armed Forces, where cadets from the Army, Navy, and Air Force train together before proceeding to pre-commissioning training at their respective service academies. Located in Khadakwasla near Pune, Maharashtra, the NDA is the world’s first tri-service academy.
NDA alumni have led and participated in every major conflict involving the Indian Armed Forces since the academy’s establishment. The alumni include 3 recipients of the Param Vir Chakra and 9 recipients of the Ashoka Chakra.
The NDA, or National Defence Academy, is a premier institution for training selected young men for officer-level entry into the Armed Forces of India. It is not merely an institution but a way of life that transforms young cadets into honorable, physically and mentally competent officers prepared for any adversity.
The training at the NDA is rigorous. In addition to service training specific to the Army, Navy, and Air Force, cadets also receive academic instruction to complete a graduation-level degree in Arts, Sciences, or Computers. The training is divided into six terms, with a total duration of three years. Upon completing their training, cadets are awarded their bachelor's degree at the NDA passing-out parade. They then proceed to their respective service institutes: the Indian Military Academy (IMA) for Army cadets, the Air Force Academy in Hyderabad for Air Force cadets, and the Indian Naval Academy in Kerala for Naval cadets.
