|---|---|---|
| NDA 1 | January | 16.5 – 19.5 years |

Why NDA Calculations Are Strict?
NDA is a defence entry at a young age. Training standards require candidates to be within physical and mental developmental range.
Hence:
- Even 1 day outside the DOB range makes a candidate ineligible.
- Age is checked using matriculation certificate only (no alternative proof accepted).
- No relaxation is provided except for minor administrative cases.
- Female and male candidates have the same age limit.
Eligibility Requirements Linked to Age
Your age alone is not enough. You must fulfil:
✔ Educational Eligibility
- 12th pass / appearing
- For Air Force & Naval Wing: Physics + Maths mandatory
- For Army Wing: any stream acceptable
✔ Marital Status
- Must be unmarried
- Married candidates are strictly ineligible
✔ Citizenship
Must be:
- Indian citizen
OR - Subject of Nepal
OR - Bhutan
OR - Tibetan refugee (with specific dates)
✔ Physical Standards (Age-dependent)
You must meet the Ministry of Defence medical norms.

Height Requirements (Important Age Connection)
| Wing | Minimum Height |
|---|---|
| Army | 157 cm |
| Navy | 157 cm |
| Air Force | 162.5 cm |
Age affects height expectations — UPSC considers bone growth parameters for 16.5–19.5 year candidates.
NDA Age Limit for Girls (Female Candidates)
Ever since Supreme Court allowed women to appear for NDA, both genders share the same age requirements:
- Minimum: 16.5 years
- Maximum: 19.5 years
Female candidates must also meet:
- UPSC educational eligibility
- MoD medical standards (with separate parameters for female candidates)
NDA Age Limit for Army, Navy & Air Force
There is no separate age limit for different wings.
All wings follow: 16½ to 19½ years.
However, educational eligibility differs:
- Army → any stream
- Navy/Air Force → Physics + Maths
NDA Age Limit for Class 12 Students
Yes, class 12 appearing (current year) students are eligible.
They must:
- Meet age range
- Pass class 12 before the date mentioned by UPSC
Age limit remains the same.
