The Indian Economic Service and Indian Statistical Service are Group A Central Civil Services recruited through a single UPSC examination — and they are the only central examinations built specifically for Economics and Statistics postgraduates.

The IES was established in 1961, to give the government a dedicated cadre of professional economists driving data-driven policy. Officers work on economic analysis, policy advisory, budget formulation and the monitoring of economic schemes across central ministries — including the Ministry of Finance and NITI Aayog.
The 2026 cycle notified 44 vacancies — 16 IES and 28 ISS. The written examination was held on 19, 20 and 21 June 2026; the answer key is out and interview dates are awaited.

There is an asymmetry between the two services that determines which one most candidates should target, and it is not the one they expect: IES requires a postgraduate degree. ISS does not.
Overview
| Point | Detail |
|---|---|
| Conducting Body | Union Public Service Commission |
| Notice | Examination Notice No. 07/2026-IES/ISS |
| Services | Indian Economic Service (IES) · Indian Statistical Service (ISS) |
| Grade | Grade IV (Junior Time Scale), Group A |
| Vacancies (2026) | 44 — IES 16, ISS 28 |
| IES qualification | Post-Graduate degree in Economics / Applied Economics / Business Economics / Econometrics |
| ISS qualification | Bachelor’s with Statistics as a subject — or Master’s in Statistics |
| Age | 21 to 30 as on 1 August 2026 |
| Written | 1000 marks, 6 papers |
| Interview | 200 marks — final merit out of 1200 |
| Pay | Level 10 — ₹56,100 – ₹1,77,500 |
| Fee | ₹200 — nil for women, SC, ST, PwBD |
| Portal | upsc.gov.in / upsconline.nic.in |
1. The Asymmetry — IES Needs a Master’s, ISS Does Not
| Service | Qualification |
|---|---|
| IES | Post-Graduate Degree in Economics, Applied Economics, Business Economics or Econometrics, from a recognised university or a foreign university approved by the Central Government |
| ISS | Bachelor’s Degree with Statistics / Mathematical Statistics / Applied Statistics as a subject — or a Master’s degree in Statistics / Mathematical Statistics / Applied Statistics |
For IES, a simple graduation degree is not sufficient. The Master’s is mandatory.
For ISS, it is not. A bachelor’s degree with Statistics as a subject qualifies — one source specifies Statistics in all years of the degree.
And ISS carries more vacancies: 28 against IES’s 16.
So the service with the lower qualification bar has the larger intake. A candidate with a B.Sc carrying Statistics through all three years is eligible for 28 posts; a candidate with a Master’s in Economics is eligible for 16.
This is worth stating plainly because IES has the higher public profile, and candidates with statistics backgrounds routinely assume they need a Master’s to apply.
Note: a Master’s in Statistics also qualifies for ISS. The bachelor’s route is an alternative, not a substitute.
2. Eligibility
| Criterion | Detail |
|---|---|
| Age | 21 to 30 years as on 1 August 2026 — born between 2 August 1996 and 1 August 2005, both dates inclusive |
| Relaxation | Per UPSC rules for reserved categories |
| Nationality | Indian citizen; subjects of Nepal or Bhutan; persons of Indian origin who migrated from Pakistan, Burma, Sri Lanka, or the East African countries of Kenya, Uganda, Tanzania, Zambia, Malawi, Zaire, Ethiopia, or Vietnam, with intention of permanent settlement — with a Government of India eligibility certificate |
| Final-year candidates | May apply provisionally, but must submit proof of passing the degree by document verification |
On attempts: published sources are inconsistent on the attempt limit for IES/ISS. Verify the position in the notification rather than relying on secondary guidance.
Note the final-year provision. Unlike ISRO, which excludes result-awaited candidates entirely, UPSC permits provisional application — as do UGC NET and CSIR NET. A candidate in the final year of a Master’s in Economics can sit IES.
3. Examination Pattern
Two stages. Both services carry 1000 marks written and a 200-mark interview — but the papers differ entirely.
IES — Six Papers, All Descriptive
| Paper | Subject |
|---|---|
| I | General English |
| II | General Studies |
| III | General Economics I |
| IV | General Economics II |
| V | General Economics III |
| VI | Indian Economics |
All questions in IES are subjective — conventional type. There are no objective papers. Each paper is 3 hours.
The consequence for preparation is direct. Answer writing is the examination. As one preparation guide puts it: “All papers are descriptive — your ability to present economic arguments clearly, with diagrams and equations, determines your score.”
UPSC tests clarity of economic thinking, not rote memorisation.
ISS — Two Objective, Two Descriptive
| Paper | Subject | Type |
|---|---|---|
| I | General English | Descriptive |
| II | General Studies | Descriptive |
| III | Statistics I | Objective |
| IV | Statistics II | Objective |
| V | Statistics III | Descriptive |
| VI | Statistics IV | Descriptive |
Statistics I and II are objective — 80 questions, 200 marks each.
Statistics III and IV are descriptive, with short-answer and long-answer questions. It is compulsory to attempt the short answer and one long answer question from each section.
All four Statistics papers are calculated out of 800 marks. All six papers total 1000 marks. The final cut-off is calculated out of 1200 marks, including the interview.
Negative Marking — ISS Only
A penalty of 0.33 marks applies for every wrong answer in the ISS objective papers — Statistics I and II.
IES has no negative marking, because it has no objective papers.
Minimum qualifying marks are reported at 10% per paper for General, OBC, ST and PH candidates. Confirm in the notification.
The Interview
Viva Voce / Personality Test — 200 marks. It evaluates personality, knowledge and aptitude.
Only candidates who qualify the written examination are called. Final selection is on the combined marks of the written examination and the interview — out of 1200.
Note the weighting: 1000 written to 200 interview — approximately 83:17. Heavier on the written stage than ISRO (50:50) or AIIMS walk-ins (100% interview), and comparable to IBPS PO (80:20).
4. Salary and Career
| Component | Detail |
|---|---|
| Grade | Grade IV — Junior Time Scale, Group A |
| Pay Level | Level 10, 7th CPC |
| Basic | ₹56,100, scale to ₹1,77,500 |
| Gross | Approximately ₹90,000 to ₹1,00,000+ with DA, HRA, Transport Allowance and other benefits |
| Highest post | Principal Adviser / Secretary level — approximately ₹1,82,200+ in basic pay |
Context across this series: Level 10 at ₹56,100 is the same entry as ISRO Scientist/Engineer ‘SC’ and DRDO Scientist ‘B’, and a gross of ₹90,000–₹1,00,000 places it alongside them — above IBPS PO (₹74,000–76,000), below RBI Grade B (₹1,54,936).
The distinction is the ceiling. IES and ISS run to Principal Adviser / Secretary level at approximately ₹1,82,200+ basic — a Group A career track into the senior economic and statistical leadership of the Government of India.
Posting is anywhere in India, under Central Government Ministries and Departments as decided by the authority. Selection does not guarantee posting in a preferred city.
What the Officers Do
IES officers work on economic analysis, policy advisory, budget formulation and the monitoring of economic schemes across central ministries — including the Ministry of Finance and NITI Aayog. The service was created to provide professional economists driving data-driven economic policy-making, analysis and development planning.
ISS officers manage the statistical data processing and national statistical services of the Government of India.
5. The Competition
44 vacancies. For IES specifically, one source places the selection rate below 0.30%.
Vacancy history: the 2023 cycle carried 18 IES and 33 ISS posts. 2026 carries 16 and 28. The numbers are small and have contracted slightly.
Vacancy figures are tentative and may be changed by UPSC.
The honest framing: this is a specialised examination with a tiny intake, and it should be approached as such. But the competing field is correspondingly narrow — Economics postgraduates for IES, Statistics graduates for ISS — rather than the two-crore field of a general recruitment.
For candidates already preparing for the Civil Services Examination, one source notes that the General Studies and English papers will be familiar — the overlap is real, though the subject papers are not.
6. Application
Entirely online. The 2026 window ran 11 February to 3 March 2026.

- Log in and select the IES/ISS module from the examination dashboard.
- Choose either Indian Economic Service or Indian Statistical Service.
- Enter category, disability status, address, educational qualifications and exam centre preference.
- Upload photograph and signature. The system also captures a live photo during the process.
- Pay the fee — ₹200 for General/OBC/EWS male candidates. Women, SC, ST and PwBD candidates pay nothing.
- Submit and download the confirmation page.
Apply Early — And Not for the Usual Reason
Exam centre allotment follows a “first-apply-first-allot” basis for most cities.
This is a concrete reason to apply on day one rather than day twenty. It is not merely about avoiding server congestion — the centre you sit in is decided by when you apply.
Applications are processed online only. No offline applications are accepted.

8. Assessment
In favour:
- The only central examination designed specifically for Economics and Statistics postgraduates
- Group A Central Civil Service at entry — Grade IV, Junior Time Scale
- Level 10, ₹56,100, gross ₹90,000 – ₹1,00,000+, with a ceiling at Principal Adviser / Secretary level around ₹1,82,200+ basic
- ISS accepts a bachelor’s with Statistics — and carries 28 of the 44 posts
- Fee ₹200, and nil for women, SC, ST and PwBD
- Final-year candidates may apply provisionally
- A narrow competing field — not a general recruitment
- General Studies and English overlap with CSE preparation
- Direct influence on national economic and statistical policy
Against:
- 44 vacancies — 16 IES, 28 ISS. Among the smallest intakes covered in this series
- IES selection rate reported below 0.30%
- Age 21 to 30 — narrower than State PSC (40–42) and RRB NTPC graduate (36)
- All IES papers are descriptive — a different skill from every objective examination in this series
- 0.33 negative marking in the ISS objective papers
- Posting anywhere in India, with no preferred-city guarantee
- Pen-and-paper offline mode
Recommendations:
If you hold a bachelor’s degree with Statistics through all years, check ISS before assuming you need a Master’s. It is the wider door and it holds 28 of the 44 posts.
If you are an Economics postgraduate, IES is the only central service built for you — but understand that it is an answer-writing examination. Six descriptive papers, three hours each. Reading economics is not preparing for it; writing economics is. Practise full-length answers with diagrams and equations, and work the Economic Survey and Union Budget directly.
If you are already preparing for CSE, the General Studies and English papers transfer. The subject papers do not — but two of six are already covered.
And apply on the first day. Exam centres are allotted first-apply-first-allot.
