What Is the UPSC IES/ISS Exam?
Every year, the Union Public Service Commission (UPSC) conducts two little-known but very important exams in India — the Indian Economic Service (IES) and the Indian Statistical Service (ISS). These are not the common civil services, as they recruit professionals who will design the systems India uses to collect economic data, develop policy, and analyse national data.
Officers selected through the IES are assigned to ministries and departments where they conduct economic research, develop policy, and advise the government on economic and fiscal matters. Their ISS colleagues conduct large-scale surveys, data, and statistical analyses and reports for the National Sample Survey Office and the Ministry of Statistics and Programme Implementation. These are Group A Gazetted Officer positions, which are central government positions that carry significant power and responsibility. The 2026 notification for the UPSC IES and ISS Exams was released on February 11, 2026, with official information available on the UPSC website at upsc.gov.in. There are 44 vacancies — 16 for IES and 28 for ISS.
UPSC IES/ISS 2026: Important Dates
The 2026 application cycle began on February 11, 2026, and ended on March 3, 2026. Those who did not apply in 2026 will have to wait for 2027 notification The three-day written exams will be held from June 19 to 21, 2026. The tests will be conducted in two shifts, and the admit cards will be available on the UPSC portal prior to the test. The written exam results will be posted on the site, and calls for the Personality Test will be made to those shortlisted. Document verification will take place after the interview and the medical examination.
Candidates should keep up to date with the posted results and admit cards on upsc.gov.in. The UPSC does not post individual results which is why they must be checked regularly.
Who is eligible to apply?
The eligibility criterion is age and education level. The age bracket for all applicants must be between 21 and 30 years of age as of the 1st of August, 2026. Relaxations are provided per the policy to the SC and ST candidates by 5 years, 3 years of OBC candidates, and a maximum of 10 years to the persons with benchmark disabilities.
To be eligible for the Indian Economic Service, candidates are required to have a Master’s degree, i.e., MA / MSc, in Economics / Applied Economics / Business Economics / Econometrics from a recognised university. Therefore, a candidate with a simple undergraduate degree in Economics does not qualify.
To be eligible for the Indian Statistical Service, candidates must either possess a Bachelor's degree with one of the following subjects - Statistics / Mathematical Statistics / Applied Statistics or a Master's degree in one of those subjects. Candidates in the final year and awaiting results can provisionally apply, but must provide proof of meeting the educational qualifications before submitting the detailed application form for the Interview. All Indian citizens are eligible to apply. Nationals of Nepal and Bhutan, along with certain categories of Migrants with an Eligibility Certificate granted by the Government, are also entitled to apply, subject to the conditions laid down in the official notification.
Exam Pattern and Selection Process
The selection process involves four steps: a written exam, a Viva Voce or Personality Test, document verification, and a medical exam. The written exam is done for a total of 1,000 marks. There are two papers for each service—General English and General Studies—each for 100 marks, and the remaining papers test the core subjects of the services. In the case of IES, the core subject is economics, while for ISS the core subject is statistics. The evaluation for these subjects is expected to be on the level of a master’s exam at a university in India.
The Personality Test is for 200 marks. The final merit is based on the written exam and the interview. Official answer keys are not published by the UPSC; however, coaching centres unofficially publish answer keys based on the exam question papers. The application fee is Rs. 200 for male candidates from the General, OBC, and EWS categories. Female candidates from the SC, ST, and PwBD categories do not have to pay a fee. Payments can be made online through net banking, debit/credit cards or through an SBI challan.
Career Opportunities and Remuneration
Passing the Indian Engineering Services (IES) and Indian Statistical Services (ISS) examinations will place a candidate in the Junior Time Scale of a central government technical service. Appointments will be made at Pay Level 10 of the 7th Pay Commission matrix with a basic pay range of Rs. 56,100 to Rs. 1,77,500 with applicable allowances. Both the IES and ISS have structured career paths and will result in senior advisory and administrative positions. The postings can be anywhere in India across the central government ministries and departments. The places of postings will be decided by the government. While preferences will be considered, they are not guaranteed.
Both service examinations provide an opportunity to work with senior government officials and provide firsthand experience in the formulation of national policies, something that other government service examinations, that provide an opportunity to work as a subject, do not offer.
Study Plan for Candidates
The Economics papers for the Indian Economic Service (IES) include micro- and macroeconomics, public finance, international trade, and Indian economic policies, whereas the Indian Statistical Service (ISS) papers include concepts such as probability, statistical inference, linear models, sampling theory, and econometrics.
Candidates are encouraged to use their postgraduate studies as a foundation rather than reinventing the wheel. Utilising NCERT texts, university textbooks on economics and statistics, and past years’ UPSC IES/ISS question papers are the best study strategies. Given the descriptive format of both exams, it is crucial to practice past papers under time constraints, as both exams are primarily conceptual. Despite coaching options available in cities like New Delhi and Hyderabad, most candidates have found success through self-study. A small positive review of the descriptive papers is the allowance of a non-programmable scientific calculator.
