UPSC eligibility: age, attempts, degree & nationality
UPSC eligibility differs sharply across its six exams. CSE asks for a graduate degree, age 21-32 General (with category relaxations) and a capped 6 attempts; NDA goes the other way - 16.5-19.5 years and only Class 12 PCM for Air Force / Navy. CDS, CAPF, ESE and CMS sit between, each with its own age band and qualification floor. This page is the per-exam breakdown for the 2027 cycle.

- Degree:a bachelor's in any discipline from a recognised university. Final-year students may sit Prelims and submit proof before Mains.
- Nationality: Indian citizen for IAS / IPS; some other services allow specified categories of non-citizens per the notification.
- Age & attempts: see the category table below (as on 1 August of the exam year).
How does the age and attempts limit vary by category?
| Category | Upper age | Attempts |
|---|---|---|
| General | 32 | 6 |
| EWS | 32 | 6 |
| OBC | 35 | 9 |
| SC / ST | 37 | Unlimited (up to age limit) |
| PwBD | +10 yrs relaxation | 9 (Gen/EWS/OBC); unlimited SC/ST |
Other UPSC exams - age & qualification
| Exam | Age (indicative) | Qualification |
|---|---|---|
| NDA & NA | ~16.5-19.5, unmarried | 10+2 (PCM for Air Force/Navy) |
| CDS | ~19-25 | Graduate (engineering for IMA/INA/AFA) |
| CAPF (AC) | ~20-25 | Graduate; physical standards apply |
| ESE | ~21-30 | Engineering degree (4 streams) |
| CMS | up to ~32 | MBBS (final-year eligible per notification) |
Common eligibility questions
- Any degree stream? Yes for Civil Services - engineering, arts, science, commerce all qualify.
- Distance / open-university degree? Acceptable if from a recognised university.
- Number of attempts used by Prelims? Each Prelims appearance = one attempt regardless of how far you progress.
- Physical standards? Required for NDA/CDS/CAPF and the IPS/IFoS medical; not for most civil posts beyond a standard fitness check.
Age window in detail: relaxations and the reference date
The 21-32 General-category window for Civil Services is checked as on 1 August of the exam year. A candidate must have completed 21 years and not attained the upper limit by that date. Category-wise upper-age relaxations stack on top of the General ceiling.
- OBC (NCL):+3 years (upper limit 35) on production of a valid OBC non-creamy-layer certificate dated as per UPSC's rule.
- SC / ST: +5 years (upper limit 37).
- PwBD (benchmark disability): +10 years on top of the category ceiling, subject to functional eligibility for the post.
- Defence services personnel: +5 years for those disabled in operations during hostilities; +3 years for ex-servicemen meeting the prescribed service criteria.
- J&K domicile, certain widows / divorced women: additional relaxations apply per the notification - always check the current year's detailed rules.
Attempt counting - what actually consumes an attempt
The attempts limit is a per-life count, not per-year. Once exhausted, the aspirant is out of CSE permanently regardless of age. The rule for what counts is precise.
- Appearing in Prelims = one attempt. Even if you write only one paper and walk out, the attempt is consumed.
- Submitting the form but not appearing does not count as an attempt.
- Disqualification or cancellation of the candidature for malpractice or wrong declaration counts.
- Mains and Interview do not consume separate attempts - they are stages within the same cycle.
Citizenship - the often-misread rule
UPSC's citizenship rules are not uniform across services. The Civil Services Examination feeds many services with different statutory bases, so the eligible pool varies.
| Service | Citizenship required |
|---|---|
| IAS / IPS / IFS | Indian citizen only |
| Other services (Group A & B) | Indian citizen, OR subject of Nepal / Bhutan, OR Tibetan refugee who came to India before 1 Jan 1962 with the intention of permanent settlement, OR a person of Indian origin who migrated from specified countries with the intent of permanent settlement (per notification) |
A candidate other than an Indian citizen must furnish an eligibility certificate from the Government of India before final appointment. They can appear for the exam but service allocation will exclude IAS/IPS/IFS.
The graduate-degree rule - and final-year students
The degree must be from a university incorporated under a central, state or provincial act, or declared as deemed-to-be a university, or any institution authorised by UGC to award a degree. The discipline does not matter for CSE.
- Final-year graduation students are eligible to sit Prelims. They must produce proof of having passed the qualifying examination along with the Mains application (DAF-I).
- Professional and technical degrees from recognised universities (engineering, medicine, law, CA finals) qualify.
- Distance, open-school and correspondence degrees qualify if the awarding university is recognised by UGC / DEB.
- Equivalent foreign degrees need an equivalence certificate from the Association of Indian Universities or equivalent body.

- NDA: unmarried Indian citizens (and certain non-citizens), aged 16.5-19.5 on a notified reference date. Class 12 from a recognised board. The Air Force and Navy wings additionally require Physics, Chemistry and Mathematics at 10+2. The Army wing accepts any 10+2 stream. Female candidates have been admitted since the SSB rules opened.
- CDS:graduate from a recognised university, generally aged 19-25 (varies by wing). IMA accepts any graduate; INA needs engineering; AFA needs a graduate with Physics & Mathematics at 10+2 OR an engineering degree; OTA accepts graduates of any stream including women.
- CAPF (AC): Indian citizen, 20-25 years old, graduate of a recognised university. Physical standards (height, chest, vision) and the PST/PET stage are mandatory. Reserved categories get the standard relaxations.
The most common eligibility rejections
- Wrong category certificate format - OBC-NCL certificates must be on the central-list format with a recent financial-year non-creamy-layer declaration. State-list OBC certificates do not work for CSE.
- Date-of-birth mismatch between Class 10 certificate and the application form. UPSC accepts only the DOB recorded in the matriculation certificate.
- Attempt over-declaration or under-declaration - either inflates risk of cancellation. Maintain an honest log from your first appearance.
- PwBD certificate from non-notified authority - only certificates from notified medical boards are accepted.
- Final-year proof missing at Mains stage - candidates who clear Prelims while in final year must hold the result before Mains begins; otherwise the candidature is rejected.
