The Indian Naval Academy inducts a fresh batch of trainees called 'cadets' every six months for two broadly different types of entries and conducts four different types of courses for the Navy and the Coast Guard. All permanent commission officers in the Navy graduate from either the flagship Indian Naval Academy Course (INAC) of four years duration with a BTech degree, or the MSc (Applied Electronics and Communications) course, which the ex-National Defence Academy (NDA) cadets undergo after passing out from the NDA.

Indian Naval Academy Course (MSc)

The INAC (MSc) cadets are essentially those who have completed their three year training at National Defence Academy (NDA), Khadakwasla and join their INAC (BTech) counterparts during the final year of training at Indian Naval Academy (INA). These cadets undergo a carefully-structured two year MSc in Applied Electronics & Communication, run under the aegis of the Jawaharlal Nehru University (JNU), New Delhi, of which the first year is completed here at the INA and the final year onboard the 1st Training Squadron during their afloat training phase. The INAC (MSc) cadets pass out through the portals of INA along with their INAC (BTech) counterparts on successful completion of first year of MSc programme.
