But first. Before books. Before coaching. Before physical training. The one question that always comes first is: What is the NDA age limit?

In 2025, NDA is still one of the toughest and most prestigious exams. Candidates in India want to know everything. They search again and again: “NDA age eligibility in 2025.”
This blog gives you the entire guide. From rules to timelines. From age relaxations to age-wise preparation. Everything you want to know about NDA age.
NDA Age at a Glance
| Attribute | Details |
| Exam Name | National Defence Academy (NDA) Exam |
| Conducted By | Union Public Service Commission (UPSC) |
| Frequency | Twice in a year (NDA 1 and NDA 2) |
| Posts Offered | Army, Navy, Air Force cadets |

NDA Age Limit 2025 (Basic Rule)
The age rule is firm. Only candidates of 16.5 years to 19.5 years are eligible.
- Minimum age: 16.5 years
- Maximum age: 19.5 years
This means:
- If you are below 16.5, you are underage.
- If you are above 19.5, you are overage.
The NDA age rule is for boys as well as girls.
NDA 1 2025 Age Limit (April Exam)
| NDA Exam | Exam Month | Date of Birth Range (Eligible) | Age Range |
| NDA 1 2025 | April 2025 | 2 July 2006 – 1 July 2009 | 16.5 – 19.5 years |
If your date of birth falls in this range, you can write NDA 1 in 2025.
NDA 2 2025 Age Limit (September Exam)
| NDA Exam | Exam Month | Date of Birth Range (Eligible) | Age Range |
| NDA 2 2025 | September 2025 | 2 Jan 2007 – 1 Jan 2010 | 16.5 – 19.5 years |
This means NDA 2 2025 gives a chance to a slightly younger group.
Why NDA Age Rules Are Strict
People often ask why NDA age is so fixed. The reasons are:
- Training requires young bodies and minds.
- Cadets must be shaped from teenage years.
- The academy wants discipline and adaptability.
- Defence services need officers to join young, so they serve longer.
This is the reason NDA age has no SC/ST/OBC relaxation. In contrast to other examinations, rules are equal for all.
NDA Age Compared to Other Defence Exams
| Exam | Age Limit | Relaxations |
| NDA | 16.5 – 19.5 years | No relaxation |
| CDS (Combined Defence Services) | 19 – 25 years | Some category relaxations |
| AFCAT | 20 – 24 years | Few relaxations |
| Agniveer Entry | 17.5 – 21 years | Limited relaxations |
This shows NDA is the youngest Indian Armed Forces entry point.
Why NDA Age Matters for Students
NDA age eligibility decides everything for students.
- When to prepare
- When to go for coaching
- When to focus on fitness
- Number of attempts possible
If a student knows about NDA age regulations at an early stage, he can plan. A student who begins preparing from 16 years of age has 3–4 attempts. A student who prepares late will get only 1 attempt.
Year-by-Year Journey (Age 15–20)
| Age | Stage | Action |
| 15 | Class 10 | Build basics, improve English, start fitness |
| 16 | Class 11 | First look at NDA syllabus, go for coaching if available |
| 17 | Class 12 | First NDA attempt becomes viable |
| 18 | After Class 12 | Serious preparation, full attempts |
| 19 | Final attempt | Need to balance NDA with graduation |
| 20 | Too old | Opt for CDS or other exams |
This table shows the importance of NDA age in life planning.
Preparation Timeline by Age
Every age of NDA journey needs to be focused on.
- 16 years: Read newspapers, improve GK. Start running and push-ups daily.
- 17 years: Crack NDA mock tests. Focus on Maths and English. First attempt can be attempted.
- 18 years: Maximum preparation. Solving question papers daily. Interview and SSB preparation.
- 19 years: Maintaining a balance between NDA and college. Final attempt with total energy.
Lifestyle of NDA Cadets by Age
Once selected, cadets adopt a disciplined lifestyle. Age is involved here as well.
- At 16.5 years, cadets acquire discipline quickly.
- At 17–18 years, cadets maintain a balance between studies and drill.
- At 19 years, cadets are seniors guiding juniors.
This proves that NDA age eligibility is best suited.
Myths about NDA Age
All students have wrong notions. Let’s clear them:
- Is there any age concession for SC/ST/OBC? ❌ No. NDA age standards are consistent for all.
- Can married individuals apply? ❌ No. Only unmarried individuals in NDA age bracket are qualified.
- Can girls apply? ✅ Yes, girls can apply as of 2021. NDA age standards are consistent for boys and girls.
NDA Age and Attempts
Students are curious: “How many attempts can I provide?”
It varies depending on your age.
- If you are 16.5 when you begin, you can provide 4–5 attempts.
- If you are 18, you can provide 2 attempts.
- If you are 19, you might have just 1 attempt.
That’s why early preparation is important.
Fitness by Age for NDA
Fitness is equally crucial as exams.
- At 16–17: Develop stamina with running.
- At 18: Develop upper body with push-ups, pull-ups.
- At 19: Work on endurance.
Cadets must be physically fit while they report to NDA. Age gives the opportunity to prepare.
