The Union Public Service Commission conducts the Civil Services Examination (CSE) to recruit for the Indian Administrative Service (IAS), the Indian Police Service (IPS), the Indian Foreign Service (IFS), the Indian Revenue Service and a range of other Group A and Group B central services.

The CSE 2026 notification carried 933 vacancies, of which 66 are reserved for PwBD candidates — a figure lower than each of the preceding two years. Alongside it, 80 vacancies were notified for the Indian Forest Service.
Two points cause more confusion in this examination than any others, and both are addressed at the outset below: “IFS” refers to two entirely different services, and a candidate cannot apply for IAS directly.

The 2026 cycle is presently at the Mains stage. The Preliminary Examination was held on 24 May 2026, and the Mains application window is open from 13 July to 22 July 2026.

1. The Two Meanings of “IFS”
This is the single most common confusion in Civil Services preparation, and it has practical consequences.
| Service | Abbreviation | Recruited through | Degree required |
|---|---|---|---|
| Indian Foreign Service | IFS | CSE — the same examination as IAS and IPS | Any bachelor’s degree |
| Indian Forest Service | IFoS | A separate examination, which shares only the CSE Preliminary | Bachelor’s degree in specified subjects only |
The Indian Foreign Service (IFS) is a central service allocated through the Civil Services Examination, exactly as IAS and IPS are. Any graduate is eligible.
The Indian Forest Service (IFoS) is a distinct all-India service with its own examination. Candidates sit the common CSE Preliminary, but thereafter the paths diverge entirely.
Indian Forest Service — The Differences That Matter
| Aspect | IFoS |
|---|---|
| Degree | Bachelor’s in science, agriculture, forestry or engineering subjects — not any degree |
| Age | 21 to 32 years, with relaxations |
| Prelims | Shared with CSE — General Studies I and CSAT |
| Mains | General English, General Knowledge, and four optional papers from two subjects |
| Interview | Separate |
| Physical standards | Stringent — a genuine selection factor |
| Vacancies (2026) | 80 |
IFoS is widely regarded as tougher than IAS, on account of the limited vacancies, the higher cut-off, the specialised science-based optional subjects, and the stringent physical standards required for final selection.
The practical instruction: a candidate with an Arts or Commerce degree cannot sit IFoS. A candidate with a science, agriculture, forestry or engineering degree may sit both, using the shared Prelims — and should consider doing so, since the marginal cost is a second Mains application rather than a second Prelims.
2. You Cannot Apply for IAS Directly
IAS, IPS and IFS are all recruited through the same Civil Services Examination. The Prelims, Mains and Interview are common to all.
Service allocation is determined after the interview, on the basis of rank and the candidate’s stated preference, subject to availability.
A candidate cannot apply for a specific service. You sit the common examination, and you are allocated.
This has a direct planning consequence: the preference order submitted with the application is the only instrument a candidate has over which service they enter, and it operates only within the constraint of rank. Preferences should be considered carefully rather than filled by default.
3. Eligibility
Educational Qualification
A bachelor’s degree from a Central or State university incorporated by an Act of the Central or State Legislature, an institution established by an Act of Parliament, or an institution declared deemed to be a University.
There is no minimum percentage requirement.
| Situation | Position |
|---|---|
| Final-year students | May apply for Prelims, but must produce proof of passing the degree examination before the Mains |
| MBBS final passed, internship pending | Provisionally allowed to appear for Mains |
| Diploma only | Not eligible. A diploma alone does not satisfy the requirement |
| Diploma followed by a degree | Eligible — for example, Polytechnic diploma followed by B.Tech, on completing the degree |
| Professional and technical qualifications | Eligible, where recognised by the Government as equivalent to a professional or technical degree |
| Degree from other universities | UPSC may, in exceptional cases, permit a candidate whose institution’s standard it approves |
Age
21 to 32 years as on 1 August 2026.
Candidates must have been born not earlier than 2 August 1994 and not later than 1 August 2005.
Relaxations apply to reserved categories as per UPSC norms. No age relaxation is provided for EWS candidates.
Attempts
| Category | Attempts |
|---|---|
| General | 6 |
| OBC | 9 |
| SC / ST | Unrestricted, within the age limit |
The rule that matters: an attempt is counted only when the candidate appears in the Preliminary Examination. Merely filling the form does not count as an attempt.
Once a candidate has exhausted the permitted number of attempts in the Prelims, they are no longer eligible.
Nationality
| Service | Requirement |
|---|---|
| IAS, IPS | Must be a citizen of India — non-negotiable |
| Other central services | Indian citizens; subjects of Nepal or Bhutan; Tibetan refugees who came to India before 1 January 1962 intending to settle permanently; persons of Indian origin who migrated from Pakistan, Burma, Sri Lanka, or the East African countries of Kenya, Uganda, the United Republic of Tanzania, Zambia, Malawi, Zaire, Ethiopia, or Vietnam, intending to settle permanently |
Candidates in the latter categories must hold a certificate of eligibility issued by the Government of India. This is mandatory before applying — an application without it is liable to rejection. Such candidates may appear for the examination before obtaining the certificate, but the offer of appointment issues only after the Government issues it.
NRIs and OCIs are not eligible for IAS, IPS or IFS. These services require Indian citizenship, and an NRI would need to reacquire Indian citizenship to be eligible.
4. Service Restrictions — The Rules Serving Officers Miss
The notification sets out specific conditions for candidates already appointed to or allocated a service. They are precise, and they change what a serving officer can do.
| Situation | Position |
|---|---|
| Already appointed to IAS or IFS and continuing | Not eligible to apply |
| Appointed to IAS/IFS after Prelims but before Mains | Not allowed to appear for the Mains |
| Appointed to IAS/IFS after Mains but before final results | Not considered for the final result |
| Serving IPS officer | Cannot opt for IPS again in a future examination |
The One-Time Window
Candidates allocated services on the basis of CSE 2025 or earlier are provided a final one-time opportunity to appear in either CSE 2026 or CSE 2027 without resigning from their allocated service.
To appear in CSE 2028 or later, resignation from the allocated service is mandatory.
And critically: joining the allocated service automatically cancels the option to appear in future examinations without resignation. A candidate intending to use remaining attempts beyond this window must avoid joining.
This is a genuine decision point for anyone allocated a service in 2025 or earlier who still wants IAS. The window is CSE 2026 or CSE 2027 — and it does not repeat.
5. The Three Stages
| Stage | Nature |
|---|---|
| Preliminary Examination | Objective-type screening test. Marks do not count toward the final merit |
| Main Examination | Descriptive papers — essay and general studies |
| Personality Test (Interview) | Final stage |
Candidates qualifying the Prelims appear for the Mains. Candidates clearing the Mains are called for the Personality Test.
Service allocation follows the interview, on rank and preference.
6. Physical and Medical Standards
This is more differentiated than most candidates assume.
| Service | Position |
|---|---|
| IAS | No formal physical fitness test during selection. All recommended candidates undergo a medical examination after the interview and must be physically and mentally fit |
| IPS | Specific physical standards — height, chest measurement and vision. Relaxation for SC, ST and specified categories per UPSC norms |
| IFoS | Specific physical fitness requirements, described as stringent |
| Non-technical services | No stringent standards, but candidates must be physically fit and mentally stable |
Physical standards apply principally to technical and uniformed services — IPS, the Indian Railway services, and the police services of Pondicherry, among others.
The standards are set out in Appendix-III of the Rules for Examination, published in the Gazette of India Extraordinary dated 2 February 2023.
All recommended candidates undergo a medical examination after the interview, conducted to UPSC and government medical authority standards.
7. The 2026 Cycle
| Stage | Date |
|---|---|
| Online application | 4 February 2026 to 24 February 2026, extended to 27 February 2026 (6 pm) |
| Preliminary Examination | 24 May 2026 |
| Mains timetable released | 10 July 2026 |
| Mains application window | 13 July to 22 July 2026 |
Note the extension. The 2026 application deadline was extended by three days. Candidates who treat a stated deadline as final occasionally miss an extension — monitor the official portal rather than assume.
Vacancy Context
933 vacancies for CSE 2026, 66 of them reserved for PwBD candidates. The figure is lower than each of the past two years.
80 vacancies for the Indian Forest Service.
Candidates should plan on the basis that vacancy counts have been contracting, and that the ratio of applicants to posts in this examination is among the most demanding in India.
8. Application Procedure
- Complete One-Time Registration (OTR) on the UPSC application portal.
- Apply online within the notified window. Complete the registration well before the last date — server load in the final hours is a recurring problem, and the window closes at a stated hour, typically 6 pm, not at midnight.
- Enter particulars accurately and set service preferences deliberately — this is the only control a candidate has over allocation.
- Pay the fee and submit; retain the printed application.
- On qualifying the Prelims, submit the Detailed Application Form for the Mains within the stated window — 13 to 22 July 2026 in the current cycle.
- Final-year candidates must produce proof of passing the degree examination with the Mains application.
Download the official notification PDF and read it in full. It contains the exam dates, eligibility rules, vacancy details, application process, fee structure and the service list.
9. Documents Checklist

10. Assessment
The Civil Services Examination is the most competitive graduate recruitment in India, and the honest framing is that of a multi-year commitment rather than an application.
What the eligibility permits, and candidates under-use:
- Any bachelor’s degree, with no minimum percentage. A third-class graduate from any discipline is fully eligible.
- Final-year students may sit the Prelims, which means a candidate can begin a year earlier than most assume.
- An attempt is counted only on appearing in the Prelims — a form filled and not sat costs nothing.
- Science, agriculture, forestry and engineering graduates may sit both CSE and IFoS on a shared Prelims, doubling the outcome from one screening examination.
What the eligibility forecloses:
- 32 years as on 1 August, with no EWS relaxation.
- 6 attempts for General candidates.
- IFoS excludes Arts and Commerce degrees entirely.
- IAS, IPS and IFS require Indian citizenship, without exception.
For serving officers: the one-time window to appear in CSE 2026 or CSE 2027 without resigning is the material provision, and it does not recur.
Frequently Asked Questions
Q1. Can I apply directly for IAS? No. IAS, IPS and IFS are all recruited through the same Civil Services Examination, with common Prelims, Mains and Interview. Service allocation is determined after the interview on the basis of rank and preference, subject to availability.
Q2. Is IFS the Indian Foreign Service or the Indian Forest Service? Both abbreviations are in use. The Indian Foreign Service (IFS) is allocated through the CSE and requires any bachelor’s degree. The Indian Forest Service (IFoS) is a separate examination sharing only the CSE Prelims, and requires a bachelor’s degree in science, agriculture, forestry or engineering subjects.
Q3. What is the age limit and how many attempts do I get? 21 to 32 years as on 1 August 2026 — born between 2 August 1994 and 1 August 2005. Attempts: 6 for General, 9 for OBC, unrestricted for SC/ST within the age limit. No age relaxation for EWS.
Q4. Is there a minimum percentage in graduation? No. A bachelor’s degree from a recognised university is the requirement, with no percentage condition.
Q5. When is an attempt counted? Only when the candidate appears in the Preliminary Examination. Filling the application form does not count as an attempt.
Q6. Can final-year students apply? Yes, for the Prelims. Proof of passing the degree examination must be produced before the Mains. Candidates who have passed the final MBBS examination but not completed the internship are provisionally allowed to appear for the Mains.
Q7. Are there physical standards for IAS? No formal physical fitness test is conducted for IAS. All recommended candidates undergo a medical examination after the interview. IPS has specific standards for height, chest and vision, and IFoS has stringent physical fitness requirements.
Q8. Can a serving officer reappear? Candidates already appointed to IAS or IFS and continuing are not eligible. Serving IPS officers cannot opt for IPS again.
