The National Defence Academy (NDA) Examination is a competitive entrance exam conducted by the Union Public Service Commission (UPSC) of India. The exam serves as a gateway for candidates who wish to join the Indian Army, Navy, and Air Force as officers. The NDA is located in Khadakwasla, Pune, and provides training to cadets who are selected through this exam.
The examination is held twice a year: typically in April and November. Successful candidates from the written exam proceed to the Service Selection Board (SSB) Interview, which includes multiple stages of testing for mental and physical aptitude, after which they are selected for training at the National Defence Academy (NDA).
What Does the NDA Examination Entail?
The NDA exam is divided into two major parts:
1. Written Examination
The written exam is conducted in two papers:
- Paper 1: Mathematics

Each paper is of 2.5 hours duration and carries 300 marks, making the total marks for the written exam 900.

2. SSB Interview (Service Selection Board)
After qualifying for the written exam, candidates who meet the cutoff are invited for the SSB Interview, which is held at various selection centers across India. The SSB interview assesses a candidate's physical fitness, psychological aptitude, and overall personality.
The SSB Interview consists of five main stages:
Stage 1: Screening Test
- This includes an intelligence test (verbal and non-verbal reasoning) and an aptitude test. Candidates are required to clear both tests to proceed to the next stage.
- Candidates also undergo a Picture Perception and Description Test (PPDT), where they interpret and describe a picture shown to them.
Stage 2: Psychological Tests
- These are designed to assess the mental and emotional suitability of the candidates. Tests like the Thematic Apperception Test (TAT), Word Association Test (WAT), and Situation Reaction Test (SRT) are conducted.
Group Testing Officer (GTO) Tasks
- Candidates are evaluated in group tasks that test leadership, teamwork, and problem-solving abilities. The tasks include group discussions, group planning exercises, outdoor group activities, and individual obstacles.
Personal Interview
- The candidate’s personality, background, and thought processes are assessed during a one-on-one interaction with the interview board.
Medical Examination
- Finally, the selected candidates undergo a medical check-up to ensure they meet the physical health standards required for military service.
3. Final Merit List
Once the written exam and the SSB interview are complete, the final selection is made based on the combined scores. The selection is determined by the written exam marks and the SSB performance.
Candidates are then sent for training at the National Defence Academy in Pune, where they receive rigorous training for three years, followed by further specialized training at their respective services' academies (Indian Military Academy (IMA), Indian Naval Academy (INA), and Air Force Academy (AFA)).
