Becoming an officer in the Indian Army is a proud and respected goal for many young Indians. An Army officer leads soldiers, takes important decisions, and serves the nation with honour. But many aspirants are confused about one thing: how does a person actually become an Army officer?
The good news is that there is no single path. The Indian Army offers many entry routes – some after Class 12, and some after graduation. This article explains all the main routes in simple language. It covers the types of commission, the entry schemes, the eligibility, the common selection process, and the training. The details here are based on official information, and aspirants should always check the latest notification before applying.
Two Types of Commissions in Indian Army
Before choosing a route, an aspirant should understand the two types of officer commission in the Army. This decides how long the officer serves.
| Type | Meaning | Trained At |
| Permanent Commission (PC) | A full career as an officer, up to the age of retirement | Indian Military Academy (IMA), Dehradun (and OTA Gaya for the TES route) |
| Short Service Commission (SSC) | A shorter career of 10 years, extendable up to 14 years, with a chance to convert to PC | Officers Training Academy (OTA), Chennai |
A Permanent Commission officer serves a full career and can rise to the highest ranks. A Short Service Commission officer serves for a fixed period and may later get the option of a Permanent Commission, based on merit and vacancies. After the initial 10 years, an SSC officer has three options: apply for a Permanent Commission, leave the service, or take a four-year extension (up to 14 years in total).

The Common Selection Process
Although the entry routes are different, they all pass through the same core selection process. No route can skip the SSB interview.
- Application – Apply online. NDA and CDS are applied for on the UPSC website; the other entries are applied for on the Join Indian Army website.
- Written Exam – Only for NDA and CDS. The other entries shortlist candidates on their academic marks.
- SSB Interview – A five-day, two-stage process. Stage I has the Officer Intelligence Rating test and the Picture Perception and Description Test. Stage II has the Interview, Group Testing Officer tasks, Psychology tests and the Conference. The board looks for Officer Like Qualities.
- Medical Examination – Candidates recommended by the SSB undergo a medical test, and only those found fit move ahead.
- Merit List – A final merit list is prepared, and selected candidates receive a joining letter for their academy.
Training and Commission
After selection, candidates train at the academy linked to their route. The three main officer training academies are:
- Indian Military Academy (IMA), Dehradun – for Permanent Commission. Training is about one year for NDA, TGC and UES cadets, and about 18 months for CDS (IMA) cadets. Cadets here are called Gentlemen Cadets and Lady Cadets. The IMA motto is “Valour and Wisdom.”
- Officers Training Academy (OTA), Chennai – for Short Service Commission. Training is about 49 weeks (roughly 11 months), and cadets are also awarded a Post Graduate Diploma in Defence Management and Strategic Studies by the University of Madras.
- Officers Training Academy (OTA), Gaya – for the basic military training of the TES (10+2 technical) entry, before technical training at the Cadet Training Wings.
NDA cadets first spend three years at the NDA, Pune, before moving to the IMA. On successful completion of training, a candidate is commissioned as a Lieutenant in the Indian Army (subject to being medically fit in the “SHAPE-1” category).
From this first rank, an officer can rise step by step to the highest ranks. To see the full ladder of ranks, read our article on the Indian Army Ranks and Insignia, and learn about the highest rank of all in our article on the Field Marshal of India.
A Note for Women Defence Aspirants
Women can also become Army officers. The induction of women into the officer cadre began in 1992, and women officers are trained at the OTA, Chennai. Today, women can apply through several routes, including the NDA, the CDS, SSC Technical, NCC Special Entry and JAG. Over the years, the Army has steadily opened more opportunities for women officers, including Permanent Commission in many branches.
