IOCL Bongaigaon Apprentice 2026 Phase II: Seats, Eligibility and the Two-Step Application
Indian Oil Corporation Limited (IOCL) has released a fresh apprentice notice for its Bongaigaon Refinery in Assam. Advertisement No. BGR/Appr/2026/04, dated 28 September 2026, offers 58 apprentice seats in three trades. The good news for many of you is simple: there is no written test. Selection is based on the marks you already scored in your B.Sc or Diploma. This is the second 2026 round at Bongaigaon, so if you missed the March round, here is another chance to train inside one of India’s major PSU refineries.
Applications opened on 28 September 2026 and close on 18 October 2026 at 5 PM. This round is open to B.Sc (Maths, Physics, Chemistry or Industrial Chemistry) graduates and Instrumentation Diploma holders. Applying here is a two-part job, and finishing only one part makes the application invalid. This article explains the seats, the eligibility rules that can disqualify you, and both application steps. Read it fully before you start, and follow GovtJobsAlert.in for the next updates on this round.

What Are the Vacancy Details for IOCL Bongaigaon Apprentice 2026 Phase II?
The category split is different for each trade, so check the row for your own trade.
| Trade (Code) | Category-wise Seats | Seats |
|---|---|---|
| Trade Apprentice – Attendant Operator (Chemical Plant), Discipline Chemical (Code 101) | UR 17 / EWS 4 / SC 3 / ST 1 / OBC (NCL) 11 / PwBD 0 | 36 |
| Trade Apprentice (Boiler), Discipline Mechanical (Code 103) | UR 6 / EWS 1 / SC 1 / ST 2 / OBC (NCL) 4 / PwBD 0 | 14 |

| All three trades | – | 58 seats in total |
These seat numbers are tentative and may go up or down at the management’s discretion. The PwBD column shows 0 for every code, and PwBD reservation here is horizontal. The notification also says PwBD candidates can apply against identified seats under Code 107 only.
What Is the Eligibility for IOCL Bongaigaon Apprentice 2026?
Educational Qualification
| Code | Qualification Required | Training Period |
|---|---|---|
| 101 | 3-year B.Sc (Maths, Physics, Chemistry or Industrial Chemistry) | 12 months |
| 103 | 3-year B.Sc (Maths, Physics, Chemistry or Industrial Chemistry) | 24 months |
| 107 | 3-year Diploma in Instrumentation Engg., Instrumentation & Electronics, Instrumentation & Control Engg., or Applied Electronics and Instrumentation Engg. | 12 months |
Your course must be a regular full-time course from a recognised University or Institute, with at least 50% aggregate marks (45% for SC/ST/PwBD against seats reserved for them). Diploma holders who joined through the lateral entry scheme (Class XII Science or ITI, admitted in the 2nd year) are also eligible if they meet the marks rule. Graduates and Diploma holders should still read the conditions table below, because each condition there can disqualify you.
Which code should a B.Sc graduate choose? You can apply for only one of Code 101 or Code 103, so think before you click. Code 101 has more seats (36) and a 12-month training period. Code 103 has fewer seats, 14 in all, but a longer 24-month training, which means two full years of hands-on boiler work inside a running refinery. Seats are filled in merit order within each trade, so pick the trade you really want to learn, not the one that only looks easier.

What Is the Selection Process for IOCL Bongaigaon Apprentice 2026?
| Stage | Detail |
|---|---|
| Merit List | Ranked by aggregate percentage of all years or semesters of your qualification; first-time apprentices preferred |
| Tie-break | Older candidate first, then higher Class X percentage |
| Document Verification | Shortlisted candidates bring originals with self-attested copies |
| Medical Fitness | Pre-engagement medical examination |
| Offer of Engagement | Issued once documents and medical fitness are in order |
The notification says plainly that there is no written test. Your marks are your entire chance, so the percentage in your NAPS or NATS profile must be correct. Filling seats is at management’s discretion, so some may stay vacant if candidates are not suitable.
How to Apply for IOCL Bongaigaon Apprentice 2026 Phase II?
You must finish both steps. Doing only one of them makes your application invalid.
| Step | Action |
|---|---|
| Step I-a (Codes 101, 103) | Register on the NAPS portal, get your enrolment number, then open Apprenticeship Opportunities, pick the IOCL Bongaigaon Refinery location and your trade, and apply (Establishment ID E07191800001) |
| Step I-b (Code 107) | Register on the NATS portal, get your registration number, then apply to the IOCL Bongaigaon Refinery advertisement from your dashboard (Establishment ID EASCHC000001) |
| Check profile | Before applying, make sure your personal, education and category details and aggregate percentage show correctly; corrections are made only through the NAPS/NATS office |
| Step II (compulsory) | Open the IOCL website, go to What’s New, find Engagement of Apprentices at Bongaigaon Refinery 2026-27 (II), and submit the Microsoft Form with your NAPS/NATS registration details before 18.10.2026, 5 PM |
| Keep records | Submit only one Microsoft Form response, and save your NAPS/NATS registration print for document verification |
Use the same email ID and mobile number in both steps, and keep them active for the full apprenticeship. Details that do not match between Step I and Step II lead to summary rejection. For document verification, carry your Class X certificate, all marksheets, your category certificate and the Annexure-A affidavit if this is your second apprenticeship. Queries can go to bgrrecruit@indianoil.in.
