The Indian Naval Academy is the initial officer training establishment of the Indian Navy. Potential candidates to the undergraduate officer-trainee program of the Indian Navy apply through the National Defence Academy. NDA cadets opting to join the Navy complete three years of joint training at NDA, Khadakwasla with the Army and Air Force cadets and then they transfer to INA for the next one year. Candidates also join through 10+2 Navy Tech Entry.
The cadets have the option to major in Electronics and Communication Engineering, Mechanical Engineering or Naval Architecture and are awarded a Bachelor of Technology degree upon graduation. Upon graduation, cadets are commissioned as Sub Lieutenants in the Navy. Cadets majoring in Naval Architecture undergo an additional 6 months training at the Naval Dockyard, Visakhapatnam after graduation. They also have the option to enroll for additional post-graduate specialization in the field at the Indian Institute of Technology, Delhi.
Admission to NAVAC as graduate officer-trainees of the Indian Navy is conducted through a written examination conducted by the UPSC, followed by 5-days of testing and interviews conducted by the Services Selection Board (SSB). These tests cover general aptitude, psychological testing, medical tests, team skills as well as physical and social skills.
For the Short Service Commission (SSC) officer-trainees, selection is through merit. SSC officers have the option to apply for permanent commission based on their performance and track record. Graduating officers often go on for additional training or specialization in areas such as surface warfare, submarine warfare, naval aviation, etc. at other Naval schools.
Officers joining the Indian Coast Guard as Assistant Commandants also undergo basic training along with graduate officer-trainees of the Indian Navy.
