The NDA & NA examination is a gateway for candidates looking forward to joining Defence Forces. This is a national level exam conducted twice a year: NDA I and NDA II to help candidates make a Defence service career. National Defence Academy & Naval Academy or NDA & NA Examination will be a two-step process where candidates first need to take the exam, then qualify for the personality test or interview conducted by the Service Selection Board (SSB). The UPSC is solely responsible for issuing guidelines for selection and the final conduct of the entrance examination.
The Notification for the NDA & NA Examination is usually released in October and June, and the examinations are conducted in February and November, respectively. Only unmarried graduates are eligible to sit for the exam. Successful candidates are admitted into the respective Academies after an interview conducted by the Services Selection Board (SSB).
Admission Process of NDA & NA Examination
Applicants to the NDA are selected via a written exam conducted by the UPSC in 1995, followed by extensive interviews by the Services Selection Board covering general aptitude, psychological testing, team skills, and physical and social skills, along with medical tests. Incoming classes are accepted twice a year for semesters starting in July and January.
Applicants who join the Air Force through the flying branch also go through a test called Computerized Pilot Selection System or CPSS for short.
Cadets who are accepted and complete the program are sent to their respective training academies for one year of training before granting of commission: army cadets go to Indian Military Academy (IMA) at Dehradun, air force cadets to Air Force Academy (AFA) at Dundigal, Hyderabad, and naval cadets to Indian Naval Academy (INA) at Ezhimala, Kerala.
Squadrons and Battalions
A cadet is allotted to one of the 18 Squadrons.
- No. 1 Battalion: Alpha Squadron, Bravo Squadron, Charlie Squadron, and Delta Squadron.
- No. 2 Battalion: Echo Squadron, Foxtrot Squadron, Golf Squadron, and Hunter Squadron.
- No. 3 Battalion: India Squadron, Juliet Squadron, Kilo Squadron, and Lima Squadron.
- No. 4 Battalion: Mike Squadron, November Squadron, Oscar Squadron, and Panther Squadron.
- No. 5 Battalion: Quebec Squadron and Romeo Squadron.
Each squadron has approximately 100 to 120 cadets drawn from senior as well as junior courses under training in the Academy.
As the number of cadets joining the NDA increased annually, the Defence Ministry of India sanctioned the raising of 16th, 17th, and 18th squadrons in 2012, with the initial letter of their names being “P”, “Q” and “R” respectively. The newly raised “Panthers” squadron won the Academy cross-country run championship in its first participation in Spring 2012. The rudimentary import of the NDA’s motto “Service before Self” is first taught in the environs of the Squadron, where a cadet learns the importance of putting the Squadron’s requirements well above his own.
