Updated on: September 11th, 2023

There’s no big Difference Between the NDA and INA. The exam for both is the same which is conducted by UPSC. NDA & NA is known as National Defence Academy & Naval Academy. There are different wings in NDA & NA for which the eligibility criteria are different. Candidates have to choose the wing they aspire to join. To join the Army wing of NDA, candidates must have appeared/passed the 12th or equivalent exam and for Air Force and Naval Wings of NDA and for the 10+2 Cadet Entry Scheme at the Indian Naval Academy, candidates must be appearing/passed 10+2 of the 10+2 pattern of School Education or equivalent with Physics and Mathematics.

Purpose of the National Defence Academy (NDA)

The National Defence Academy is a training facility where students from the Army, Air Force, and Navy are trained together before beginning their pre-commission training.

  • To be admitted to the National Defence Academy, aspirants must first pass the NDA Exam, then undergo thorough interviews with the Services Selection Board (SSB), and finally a medical examination.
  • Those who pass all three rounds of the exam procedure will receive preliminary academic instruction (including physical training) at the National Defence Academy at Khadakwasla, Pune, for a three-year term.
  • The goal of training is to provide high-quality academic and technological education to cadets in order to provide them with the necessary qualifications to begin their service careers.



What is Naval Academy in NDA?

Because of its attractive surroundings, maritime traditions, and rich historical background, the Indian Navy picked Ezhimala, Kerala to house the Indian Naval Academy.

  • This university is renowned as Asia’s largest Naval Academy.
  • Candidates who wish to join the Indian Naval Academy must take the UPSC admission NDA (NA) exams or apply through the 10+2 B.Tech (SPL) route.
  • Those who choose to join the Navy must complete three years of B.Tech at the NDA and one year at the Indian Naval Academy (INA).


  • Those cadets who chose Naval Academy travel straight to INA in Kerala for their four-year program.
  • Cadets are commissioned and join the executive branch of the Indian Navy after successfully completing four years of training.
  • The Indian Navy Academy strives to prepare young men and women for careers as professional naval officers by providing them with a high-quality education as well as the necessary professional naval training.

What is the Difference Between NDA and INA?

Given the NDA Eligibility Criteria, there is no significant difference between the National Defence Academy (NDA) and the Indian Naval Academy (INA). The following are the variations between the two eligibility criteria:

  • Candidates’ age should be between 16.5 to 19.5 to apply for NDA & INA.
  • Candidates for the Army branch of the NDA must have completed class 12th or an equivalent test from a recognized board. Candidates for the NDA’s Air Force and Naval Wings, as well as the 10+2 cadet admission program at INA, must have completed class 12th or equivalent with Physics, Chemistry, and Mathematics.
  • The minimum height required by the NDA is 157.5 cm for the Army and 162.5 cm for the Air Force. INA, on the other hand, requires male candidates to be 157 cm tall and female candidates to be 152 cm tall.
  • In order to qualify for NDA, a candidate must be able to read a distant vision chart with or without spectacles at 6/6 in the better eye and 6/9 in the worse eye. In the INA, the minimum acceptable distance vision standards are 6/60, 6/60 correctable to 6/6, and 6/12 with spectacles. There should be no color or night blindness in the candidates.
  • The difference in the type of duties: There isn’t much of a difference in the kind of responsibilities one can perform if they join through the NDA-NAVY or the Naval Academy. With the help of cases, we will be able to comprehend them.
    • Case 1: If a candidate is selected on the merit list for the NDA’s naval wing, he will be required to complete a three-year course at the National Defence Academy in Khadakwasla. Naval wing cadets receive a B.Sc degree after completing three years of training and are transferred to Indian Naval Academy, Ezhimala, for the last year of training before commissioning as a Sub-Lieutenant in the Indian Navy.
    • Case 2: If a candidate is selected for Naval Academy, he will attend Indian Naval Academy, Ezhimala, for four years of training, after which he will be awarded a B.Tech degree in one of the Engineering Streams and commissioned into the Indian Navy as a Sub-Lieutenant.
  • In both the above cases, the candidate will be entitled to choose the Naval Air Arm if he passes the PABT (Pilot Aptitude Battery Test).
  • Cadets in the Pilot Cadre receive Stage 1 and Stage 2 flight training at the Air Force Academy/Naval Establishment/Indira Gandhi Rashtriya Udaan Academy after being selected (IGRUA). Candidates will be granted the coveted ‘Wings’ after successfully completing training.

NDA Vs INA: Conclusion

Each military academy is exceptional in its own right. As a result, there is no significant difference between NDA and INA.
