UPSC NDA Exam 2026: Complete Guide to Notification, Eligibility, Syllabus, and Selection Process

What is the UPSC NDA Exam?

The NDA exam - full form National Defence Academy - is a national-level entrance examination conducted by the Union Public Service Commission (UPSC) for admission to the National Defence Academy at Khadakwasla, Pune, and the Indian Naval Academy (INA) at Ezhimala, Kerala. Successful candidates join one of the three wings - Army, Navy, or Air Force - for a three-year training programme at NDA, followed by further pre-commissioning training at the respective service academies.

The UPSC NDA is held twice every year, making it one of the few defence examinations with two annual attempts. It is open to unmarried male candidates and, since a landmark Supreme Court ruling in 2021, also to unmarried female candidates, making the NDA one of the most inclusive routes into the Indian Armed Forces for school-leaving aspirants.

For NDA 2, the vacancy is:

Approximate Number of Vacancies to be Filled Through This Examination

Note:

The Indian Army publishes vacancies for men and women separately for various services and entries, based on the operational and administrative requirements of the armed forces. Although vacancies for men and women in NDA/Naval Academy are notified through a common notification and candidates appear in the same written examination, men and women are treated as separate categories for selection purposes. Accordingly, the written examination results, merit lists, and final selections for men and women are prepared separately according to the notified vacancies.

NDA Eligibility Criteria 2026

NDA eligibility is defined across three dimensions - nationality, age, and educational qualification. Candidates must satisfy all three conditions to be eligible to apply.

Nationality

The candidate must be a citizen of India, a subject of Bhutan or Nepal, or a Tibetan refugee who came to India before January 1, 1962 with the intention of permanently settling in India - subject to conditions specified in the official notification.

NDA Age Limit

The NDA age limit is strictly enforced. For NDA 1 2026 (exam expected in April 2026), candidates born between specific dates specified in the notification will be eligible. The exact birth date range is published in each notification.

NDA age limit for girls: The age eligibility for female candidates is the same as for male candidates - between 16.5 and 19.5 years as on the relevant date.

NDA Qualification

NDA after 12th is the standard entry point - the examination is designed specifically for candidates who are appearing in or have cleared the Class 12 (10+2) examination.

NDA exam for 12th pass: Candidates who have already completed Class 12 are eligible. Candidates who are appearing in Class 12 at the time of application are also eligible to apply, subject to meeting all other conditions.

Can arts students apply for NDA? Yes - arts stream students can apply for the Army wing of NDA. However, Physics and Mathematics at Class 12 level are mandatory for the Navy and Air Force wings. Arts students without Physics and Mathematics are eligible only for the Army.

NDA eligibility for girls: Female candidates are now eligible to apply for the NDA examination following the Supreme Court's order in 2021. The eligibility conditions - age, educational qualification, and physical standards - apply equally to female candidates. The marital status condition (unmarried) applies to both male and female candidates.

NDA Syllabus 2026

The NDA syllabus 2026 covers two papers - Mathematics and General Ability Test (GAT). Understanding the syllabus in detail is the first step toward a focused preparation strategy.

NDA Mathematics Syllabus

The NDA maths syllabus is broadly at the Class 11–12 level and covers:

NDA GAT Syllabus – General Ability Test

The NDA GAT syllabus (General Ability Test) is divided into two sections:

Part A - English

The NDA English syllabus covers grammar and usage, vocabulary, comprehension, and cohesion - broadly testing the candidate's ability to use English effectively. Topics include synonyms, antonyms, sentence correction, fill in the blanks, reading comprehension, and ordering of sentences.

Part B - General Knowledge

The NDA general ability test syllabus for General Knowledge covers:

NDA Exam Pattern 2026

The NDA exam pattern 2026 consists of a single-day offline (pen-and-paper) written examination with two papers - Mathematics and General Ability Test (GAT).

NDA Written Exam – Paper-wise Pattern

NDA Marking Scheme

NDA negative marking: One-third of the marks assigned to a question are deducted for every wrong answer. This makes accuracy critical - random guessing is penalised. Candidates should attempt questions they are reasonably confident about and leave genuinely uncertain questions unattempted.

NDA exam pattern – Maths and GAT breakdown: Mathematics carries 300 marks with 120 questions (2.5 marks per question). GAT carries 600 marks with 150 questions (4 marks per question), split between English (200 marks) and General Knowledge (400 marks). The higher weightage of GAT - 600 out of 900 marks - means strong General Knowledge preparation is at least as important as Mathematics proficiency.

NDA Selection Process

The NDA selection process is a three-stage process. Clearing each stage is mandatory to proceed to the next.

Stage 1 - Written Examination

The objective MCQ-based written exam as described in the exam pattern above. Candidates who clear the written exam are called for Stage 2 based on a merit list prepared by UPSC.

Stage 2 - SSB Interview

Candidates shortlisted after the written exam appear before a Services Selection Board (SSB) for a comprehensive five-day assessment. This is the NDA SSB interview process - the most distinctive and demanding stage of NDA selection.

Stage 3 - Medical Examination

Candidates recommended by the SSB undergo a comprehensive medical examination conducted by a Medical Board. Only candidates declared medically fit proceed for final merit list preparation.

Final Merit List: A combined merit list is prepared based on the written exam score and SSB marks (interview and psychological assessment). Final selection and allocation to Army, Navy, or Air Force wings depends on merit rank and vacancies.

NDA SSB Interview

The NDA SSB interview is a five-day process at one of the SSB centres across India, designed to assess the Officers' Intelligence Rating (OIR), psychological suitability, personality, and leadership potential of the candidate.

NDA SSB Process – Day by Day

Day 1 - Screening Test:

• Officer Intelligence Rating (OIR) Test: Verbal and Non-Verbal Reasoning
• Picture Perception and Discussion Test (PPDT): Candidates write a story based on a hazy image and then narrate and discuss it in a group

Candidates who clear Day 1 screening are retained. Those who do not clear are sent back the same day.

Day 2 - Psychological Tests:

• Thematic Apperception Test (TAT): Write stories based on pictures shown
• Word Association Test (WAT): Write a sentence for each word shown briefly
• Situation Reaction Test (SRT): Written responses to everyday situations
• Self-Description Test (SD): Written self-assessment

Day 3 and 4 - Group Testing Officer (GTO) Tasks:

• Group Discussion (GD)
• Group Planning Exercise (GPE)
• Progressive Group Task (PGT)
• Half Group Task (HGT)
• Individual Obstacles
• Command Task
• Final Group Task (FGT)
• Lecturette (speaking on a topic for 3 minutes)

Day 4 - Interview

A personal interview with the Interviewing Officer (IO), typically lasting 30–60 minutes, covering the candidate's background, interests, current affairs awareness, and personality.

Day 5 - Conference

A final conference attended by all assessors (GTO, IO, Psychologist), where a consensus recommendation is reached. Candidates are informed of whether they are Recommended or Not Recommended.

NDA SSB interview process - what assessors look for

The SSB is not testing academic knowledge. It is assessing Officer Like Qualities (OLQs) - including effective intelligence, sense of responsibility, initiative, self-confidence, ability to influence groups, moral courage, stamina, and cooperativeness. Genuine personality traits matter far more than coached responses.

NDA Physical Test and Medical Standards

NDA Physical Test

The NDA physical test is conducted as part of the SSB and involves participation in the GTO tasks described above - outdoor group activities including obstacle courses, rope climbing, group tasks, and command tasks. These tasks assess physical fitness, coordination, stamina, and team spirit rather than elite athletic ability.

There is no separate pre-SSB physical fitness test. However, candidates are expected to be in good general physical condition - the GTO tasks are demanding, and poor physical fitness affects performance.

NDA Physical Eligibility and Medical Standards

After SSB recommendation, candidates undergo a detailed medical examination. The NDA physical eligibility (medical standards) covers:

Height and Weight:

Weight should be proportionate to height as per the medical standards table in the official notification.

NDA physical standards for male and female candidates:

The physical and medical standards for female candidates are specified in the official notification. Height minimums and proportionate weight requirements apply. The specific standards for female candidates may differ from those for male candidates in certain parameters - aspirants should refer to the official notification for the latest details.

Other key medical requirements:

• Vision: Uncorrected visual acuity and corrected visual acuity standards are specified wing-wise. Air Force has the most stringent vision requirements.
• Hearing: No defect in hearing
• No history of mental health conditions, epilepsy, or certain chronic diseases
• Dental fitness as per prescribed standards
• No colour blindness (especially for Navy and Air Force)

NDA medical test: The medical examination is conducted at Military Hospitals. Candidates declared temporarily unfit may be re-examined after a specified period. Candidates declared permanently unfit may appeal to a Review Medical Board.

NDA Salary and Career Prospects

NDA salary begins during training and increases significantly upon commissioning as an officer.

Salary During Training at NDA

Cadets at NDA receive a stipend during the three-year training period at Khadakwasla, plus the pre-commissioning training at the respective service academies.

Salary After Commissioning

Additional benefits: Free accommodation or HRA, ration allowance, transport allowance, medical facilities for self and family, Leave Travel Concession, Canteen Store Department (CSD) facilities, Group Insurance, and pension after qualifying service. Officers also receive kit allowance, field area allowances, and various operational allowances depending on posting.

Career progression: NDA-commissioned officers follow a structured career progression - Lieutenant → Captain → Major → Lieutenant Colonel → Colonel → Brigadier → Major General → Lieutenant General → General (Army equivalent). Promotions are time-bound and merit-based. NDA graduates are among the most respected officer cohorts within the Indian Armed Forces.

Final Result: Published after completion of SSB interviews and medical examinations. Contains the final merit list of recommended candidates with their roll numbers and allocation to wings.

NDA Previous Year Question Papers

NDA previous year question papers are among the most effective preparation tools for understanding the actual difficulty level, question types, and topic distribution across Mathematics and GAT.

What PYQ analysis reveals:

• Mathematics questions are consistently at Class 11–12 level - Calculus, Algebra, and Trigonometry form the bulk of the paper
• GAT English questions test grammar and comprehension at a moderate level - regular reading practice is the most effective preparation
• GAT General Knowledge questions follow current events closely, especially in the areas of defence, science and technology, and national affairs
• Questions from Physics within GAT are particularly application-oriented - expect questions that link physical principles to practical or military contexts
• Solving 5–7 years of past papers is sufficient to identify the recurring topics and calibrate preparation level

NDA Preparation Strategy

The NDA preparation strategy must account for two distinct components - the written examination and the SSB interview - which require fundamentally different approaches.

Written Exam Preparation

Phase 1 - Build the Mathematics Foundation (Months 1–3): Start with NCERT Class 11 and 12 Mathematics - cover all chapters thoroughly, since NDA Mathematics is directly mapped to this level. Focus especially on Calculus, Algebra (Matrices, Determinants, Permutations), and Trigonometry, which collectively account for the majority of the Mathematics paper. Solve exercises from each chapter before moving to NDA-specific practice books.

Phase 2 - Cover GAT Systematically (Months 2–4): Divide GAT preparation into English and General Knowledge. For English, practise grammar rules using Wren and Martin, then shift to past paper questions. For General Knowledge, cover Physics and Chemistry using NCERT (Class 9–12 selected chapters), then build your History, Geography, and Polity base using NCERTs. Current affairs should be a daily habit from day one - read a newspaper or follow a reliable current affairs source focused on defence, science, and national events.

Phase 3 - Practice and Mock Tests (Month 3 onwards): Shift to full-length mock tests under timed conditions. Alternating between Mathematics and GAT papers builds the stamina needed for a five-hour examination day. Analyse every mock test - identify weak topics, recurring mistake patterns, and accuracy issues before attempting the next mock.

Phase 4 - SSB Preparation (Parallel to written prep, intensifying after clearing written): SSB preparation is long-term - it cannot be crammed in a few weeks. Begin building reading habits, newspaper awareness, and social interaction skills from the start. After clearing the written exam, focus on understanding the SSB process in depth, practise WAT and TAT responses, develop the ability to speak clearly and confidently for the Lecturette, and if possible, attend a genuine SSB guidance programme rather than a coached response class.

Key tips for NDA written exam:

• Negative marking makes accuracy more important than speed - do not guess blindly
• Mathematics: solve each chapter's NCERT exercises completely before moving to mock papers
• GAT: current affairs is the highest ROI investment - consistent daily reading adds up significantly over months
• Attempt at least 10 full previous year papers in timed conditions before the exam
