Union Public Service Commission IES

UPSC IES is a recruitment exam conducted by Union Public Service Commission, relevant to engineering graduates targeting technical government and PSU roles.

UPSC IES Study Material

UPSC IES, officially the Engineering Services Examination (ESE), is conducted by the Union Public Service Commission to recruit engineers for Group A and Group B technical services of the Government of India. Selected candidates join services such as the Central Engineering Service, Indian Railway Management Service, Central Water Engineering Service, Indian Telecommunications Service and the Indian Defence Service of Engineers. The exam is held in four streams: Civil, Mechanical, Electrical, and Electronics and Telecommunication Engineering.

The UPSC IES 2027 cycle is under way. UPSC issued the notification on 16 September 2026, applications closed on 6 October 2026, and the preliminary exam is scheduled for 31 January 2027. This page brings together the dates, vacancies, eligibility, exam pattern, syllabus, cut-offs, pay and a preparation plan, with links to a detailed page on each topic.

UPSC IES eligibility

Educational qualification

Candidates need a degree in engineering from a university or institution recognised under Indian law, or an accepted equivalent such as Sections A and B of the Institution of Engineers (India) examinations or an approved foreign engineering degree. For two posts, an M.Sc. with Wireless Communication Electronics, Radio Physics or Radio Engineering is also accepted: Indian Naval Armament Service (Electronics Engineering Posts) and Indian Radio Regulatory Service. Final-year students can apply, but must show proof of passing within the window given after the main result.

Stage III: Personality test

The interview carries 200 marks, with no minimum qualifying marks. In objective papers, one-third of the marks for a question is deducted for each wrong answer, and a blank answer carries no penalty. Calculators are allowed in the conventional main papers only.

What this means for you:

  • Prelims marks count: Your 500 prelims marks are added to the final merit, so prelims is not only a screening test.

  • Discipline papers carry most weight: 900 of the 1,300 marks come from your engineering stream, across one objective and two conventional papers.

  • Guessing has a cost: Three wrong answers cancel one correct answer, so attempt questions only where you can rule out options.

Older pages may still show outdated paper names, marks or durations, so follow the current notification. See the UPSC IES exam pattern page for a worked example.

UPSC IES selection process

  1. Preliminary exam (500 marks): UPSC sets minimum qualifying marks in both papers. About six to seven times the number of vacancies are admitted to the main exam.

  2. Main exam (600 marks): Two conventional papers in your discipline, answered in English. About twice the number of vacancies are called for the personality test.

  3. Personality test (200 marks): Assesses leadership, initiative, intellectual curiosity, tact, practical application and integrity.

  4. Final merit (1,300 marks): Prelims, mains and interview marks are added. Services are allotted by rank, preference, vacancies and medical fitness.

UPSC IES salary and career growth

The ESE notification does not state pay. Group A services recruited through ESE generally start at Level 10 of the 7th Pay Commission pay matrix, where the basic pay begins at Rs. 56,100 a month, plus dearness allowance, house rent allowance and other allowances. Junior Telecom Officer is a Group B post and starts at a lower level.

How to prepare for UPSC IES

Prelims

  • Build the discipline base first: Paper II and the main papers share one syllabus, so strong concepts serve both stages.

  • Do not skip General Studies: Paper I is 200 marks and covers 10 fixed topics, each worth 5 to 15 percent of the paper.

  • Practise without a calculator: Objective papers do not allow calculators, so build quick approximation habits.

Mains

  • Write answers early: Practise derivations, neat diagrams and step-by-step numericals in timed sessions.

  • Start mains preparation before the prelims result: The gap between prelims and mains is about four and a half months.

Mock tests and revision

Full-length mocks in the current pattern show you how much time each paper needs and how negative marking affects your score. Concise UPSC IES study notes on Testkart can help with fast revision in the last weeks.
