DSSSB Junior Engineer (Electrical) — Tier-II Technical Merit Exam 2026

Advertisement 06/2026 · Post Code 809/26 · 150 objective questions · 200 marks · 150 minutes · final JE merit stage.

What changes from Tier-I?

Tier-II is entirely technical, not a repeat of the 100-mark General Awareness/language section from Tier-I. Its first part checks knowledge across the qualifying Electrical Engineering subject, while the second probes whether candidates can apply concepts, reason through engineering contexts and solve problems. Both parts have separate mandatory minimum qualifying requirements. DSSSB then adds the marks of both parts for the final merit list; the first-tier score qualifies candidates for this stage but is not added to create a 400-mark final result.

📊 JE Tier-II: questions in technical parts

📊 JE Tier-II: marks from each technical part

Part I: technical knowledge, 100 questions/100 marks

The Board states that Part I is an objective paper of one-mark questions covering the entire syllabus of the qualifying subject. For this Electrical Engineering competition, preparation should connect fundamentals to applied engineering: network laws and AC calculations, single/three-phase transformers, rotating machines, electrical drives, switchgear/protection, electrical power networks and distribution, instrumentation and metering, earthing and electrical safety, and core electronics/power electronics. These are practical study categories compiled to support preparation; no exact chapter-wise distribution or separately notified engineering textbook is given on pages 14–15 of Advertisement 06/2026.

A useful technique is to identify whether a question is primarily a circuit-law calculation, a machine characteristic, a protective-device selection, an installation safety judgement or a measurement principle, then select the relevant model rather than memorising a formula detached from its assumptions. The employer-specific degree-versus-diploma rule has no effect on the question count: all applicants to the post code face the same published Tier-II structure.

Part II: application and engineering problem-solving, 50 questions/100 marks

Each Part II item carries two marks, and the advertisement explicitly describes evaluating application of concepts, problem solving, comprehension of context and application of theoretical aspects. Candidates should practise multi-step engineering reasoning: translating conditions into equivalent circuits, checking whether rated equipment and protective arrangements fit the scenario, interpreting test measurements, selecting appropriate operating assumptions and estimating losses, efficiency or electrical quantities. Avoid presuming an announced compulsory practical test or a descriptive written answer: Part II is also MCQ-based.

A mistake on a Part II question costs 0.50 mark, while a wrong Part I question costs 0.25 mark. Those deductions reflect the same quarter-of-mark rule for questions of different values. A blank answer is not an incorrect marked answer. As Part II contributes half the stage's total marks from only one-third of its questions, it deserves deliberate practice without sacrificing the separate Part I qualifying requirement.

Qualification, merit and tie handling

For Tier-II, the applicable minimum is enforced separately in Part I and Part II as well as the combined standing under the rules. The general DSSSB minimum table states 40% General/EWS, 35% Delhi OBC and 30% SC/ST/PwBD (and eligible ex-servicemen concession); final category cutoffs can be higher. Combined Tier-II marks, not Tier-I marks, determine the JE selection merit subject to the reservation roster, document eligibility and department preferences. If candidates tie on Tier-II marks, the older candidate ranks first, and identical birth dates lead to alphabetical first-name ordering in English.

Timing: 2 hours 30 minutes for 150 questions. The notice does not divide Tier-II into separately timed subtests. It does not give an actual 2026/27 examination date, centre, call-letter date, official technical textbook list or result date. Consult a DSSSB examination notice, rather than a speculative calendar, before arranging travel.
