Indian Oil Corporation Limited — a Maharatna PSU and a Fortune Global 500 company — hires technical staff through two entirely separate tracks, and candidates routinely apply to the wrong one.
Advertisement
The apprentice track engages Trade, Technician and Graduate Apprentices under the Apprentices Act, 1961/1973/1992. It runs for 12 months, pays a stipend, requires no written examination — and, as IOCL’s own notifications state, does not guarantee permanent employment.
The permanent track fills posts such as Junior Engineering Assistant, Junior Quality Control Analyst, Technical Attendant and Junior Operator through separate notifications with written tests.

The apprentice track is live now. 1,524 vacancies across the Bongaigaon, Gujarat, Mathura and Paradip refineries, with applications open until 28 July 2026 (5 PM).
And it carries a rule that disqualifies the best-qualified applicants: B.E./B.Tech, MBA, MCA, CA and LLB holders are not eligible.

1. The Rule That Disqualifies the Over-Qualified
“Candidates possessing higher professional degrees like B.E./B.Tech, MBA, MCA, CA or LLB are not eligible to apply for these positions.”
A B.Tech holder cannot apply for an IOCL apprenticeship. Neither can an MBA, an MCA, a Chartered Accountant or a law graduate.
This is the second time this shape has appeared in this series. RRB Technician does not accept an engineering diploma in lieu of an ITI for Level 2 posts. IOCL does not accept a B.Tech at all.
The principle is consistent across the technical tier: these are entry-level training and trade positions, and a higher qualification is a disqualification rather than an advantage.
For an ITI or diploma holder, that is good news. It removes the entire engineering-degree population from the competing field.
2. Eligibility — Discipline by Discipline
| Post | Qualification |
|---|---|
| Trade Apprentice — Fitter (Mechanical) | Matriculation + 2-year ITI (Fitter), NCVT/SCVT recognised, pass class |
| Trade Apprentice — Attendant Operator (Chemical Plant) | 3-year B.Sc in Maths, Physics, Chemistry or Industrial Chemistry |
| Trade Apprentice — Boiler (Mechanical) | 3-year B.Sc in Maths, Physics, Chemistry or Industrial Chemistry |
| Technician Apprentice — Chemical | 3-year Diploma in Chemical / Petrochemical Engineering, Chemical Technology, or Refinery & Petrochemical Engineering |
| Technician Apprentice — Mechanical | 3-year Diploma in Mechanical Engineering |
| Technician Apprentice — Electrical | 3-year Diploma in Electrical Engineering |
| Technician Apprentice — Instrumentation | 3-year Diploma in Instrumentation / Instrumentation & Electronics / Instrumentation & Control / Applied Electronics & Instrumentation |
| Graduate Apprentice | Regular full-time Graduate Degree in any discipline, AICTE/UGC recognised |
| Trade Apprentice — Accountant | 3-year B.Com |
| Secretarial Assistant | 3-year B.A. / B.Sc. / B.Com |
| Data Entry Operator (Fresher) | Class 12 pass |
| Domestic Data Entry Operator | Class 12 + NSQF Domestic DEO skill certificate |
The Marks Rule — And the ITI Exception
A minimum of 50% aggregate marks is required — 45% for SC/ST/PwBD candidates considered against reserved seats.
“ITI qualification requires pass class only.”
Read that carefully. The 50% threshold applies to B.Sc, Diploma, B.Com and degree holders. An ITI holder needs only a pass class.
For a Fitter-trade ITI candidate, there is no percentage bar at all — an advantage no other qualification in this notification carries.
All qualifications must be from a regular full-time course at a recognised Board, University or Institute.
Lateral-entry diploma holders are eligible — candidates admitted directly into the second year on the strength of Class XII or an ITI — provided they meet the percentage requirement based on the aggregate of all semesters.
Age
18 to 24 years, calculated as on the date specified in the notification — 30 June 2026 for the current cycle.
| Category | Relaxation |
|---|---|
| OBC (NCL) | +3 years |
| SC / ST | +5 years |
| PwBD | +10 years |
| PwBD–SC/ST | +15 years |
Note the upper limit: 24. This is the narrowest age band of any post covered across this series — narrower than Agniveer’s 21-to-… well, comparable, and narrower than every civilian post. An apprenticeship is for the recently qualified.
3. Selection — Merit, Not Examination
| Stage | Detail |
|---|---|
| 1. Merit List | Based entirely on the percentage of marks secured in the prescribed qualification for the post |
| 2. Document Verification | At the selected refinery; originals required |
| 3. Pre-Engagement Medical Examination (PEME) | Prescribed IOCL medical standards |
There is no written examination.
Shortlisted candidates are notified via their registered email addresses — so the email entered in the application must be one you monitor.
The Tie-Break Rule
Stated precisely in the notification:
“In cases where two candidates have the same percentage, the candidate with the earlier date of birth — older in age — will be given preference. If the dates of birth are also the same, the candidate with a higher percentage of marks in matriculation will be considered.”
The older candidate wins the tie. The same principle appears in Post Office GDS and Navy SSR shortlisting — the candidate with fewer remaining chances is preferred.
And the second tie-break is Class 10 marks — which is why the Matriculation certificate matters even for a graduate applicant.
4. The Two-Step Application — Miss Either and You Are Rejected
This is the most common cause of rejection in IOCL apprentice recruitment, and it is entirely avoidable.
Step I — Portal registration:
| Apprentice type | Portal |
|---|---|
| Trade Apprentices | NAPS — National Apprenticeship Promotion Scheme |
| Technician and Graduate Apprentices | NATS — National Apprenticeship Training Scheme |
Step II — IOCL application:
Apply against the IOCL notification through the Microsoft Forms link available on the IOCL website, matching your preferred refinery.
“Missing either Step I (NAPS/NATS portal) or Step II (Microsoft Forms) will result in rejection of candidature.”
Both steps are mandatory. Registering on NAPS or NATS is not applying to IOCL.
Additionally: complete E-KYC, and keep the Portal Registration Number available — it is required at document verification.
There is no application fee.
Where to Find It
iocl.com → ‘What’s New’ or the Careers / Apprenticeships section → the notification for your refinery.
5. The Refinery-Wise Structure
IOCL does not run one national apprentice notification. Each refinery issues its own, with its own advertisement number, vacancy count and dates.
| Refinery | Vacancies | Advertisement |
|---|---|---|
| Panipat Refinery & Petrochemical Complex | 637 | PR/P/Apprentice/59(2025-26) |
| Paradip Refinery | 582 | PDR/HR/01/Apprentices-26 |
| Bongaigaon, Guwahati & Digboi | 372 | Three separate notifications |
| Haldia Refinery | 279 | — |
| Bongaigaon, Gujarat, Mathura, Paradip (combined) | 1,524 | — |
Dates differ by refinery. The Bongaigaon and Guwahati window ran 29 June to 28 July 2026; Digboi ran 8 July to 31 July 2026; Haldia closes 30 July 2026 with document verification around 11 August.
Check the notification for your refinery, not the general one.
A Vacancy Concentration Worth Knowing
At Paradip, Code 101 (Chemical Plant Attendant Operator) and Code 104 (Technician – Chemical) together account for 310 of the 582 seats — the chemical discipline is the largest block.
And at the other extreme: Code 109 (Accountant) carries a single seat for the UR category — the most competitive position in that notification.
Read the code-wise table before choosing. A discipline with 310 seats and one with a single seat sit in the same advertisement.
6. Documents
The list is long, and two items are frequently missed:
- ☐ Matriculation certificate — proof of date of birth, and the second tie-break
- ☐ Class XII marksheet
- ☐ Semester-wise / year-wise marksheets of ITI, Diploma or Graduation
- ☐ Final certificate from the Board or Authority
- ☐ Conversion certificate from CGPA/OGPA/Letter Grade to percentage, where applicable
- ☐ Certificate from the Principal of the School, Polytechnic, College or Institute — confirming the date of publication of result, regular full-time mode of study, and good conduct
- ☐ SC/ST/OBC(NCL)/PwBD/EWS certificate in the prescribed central format
- ☐ Caste validity certificate — applicable only to candidates from the Western Region
- ☐ PAN Card / Aadhaar
- ☐ Portal Registration Number (NAPS/NATS)
- ☐ Passport-size colour photograph
The Principal’s certificate — confirming regular full-time study and good conduct — is a requirement few candidates anticipate and which takes time to obtain from an institution you may have left.
The CGPA conversion formula must come from the institution or university. As with the Coast Guard notification covered earlier in this series, it is a routine cause of delay at verification.
7. What the Apprenticeship Is — And Is Not
IOCL states the position plainly: “Apprenticeship is a training-based engagement and does not guarantee permanent employment after completion.”
What it provides:
- 12 months of structured industrial experience at a major refinery
- A stipend as prescribed under the Apprentices Act and IOCL’s guidelines
- Exposure to world-class technology, safety standards and professional work culture
- Experience at a refinery such as Haldia or Paradip — described as highly valued in the industrial sector and significantly enhancing employability
- A completion certificate under the Apprentices Act
Who it suits, on IOCL’s own framing:
- Candidates who recently completed ITI, Diploma or Graduation and want industrial experience
- Freshers preparing for PSU or government technical jobs
- Students planning careers in refinery, petrochemical or manufacturing
- Candidates struggling to obtain first-job experience, using the apprenticeship as an entry point
And note the cross-reference from the previous guide in this series: a Course Completed Act Apprenticeship is an accepted qualification for RRB Technician Grade III — a permanent Level 2 railway post — on the same footing as an ITI. An apprenticeship completed under the Apprentices Act is not only experience; it is a qualification that other recruiters accept.
8. The Permanent Track
Separate from the apprenticeship, IOCL recruits directly to permanent posts, including:
- Junior Engineering Assistant
- Junior Quality Control Analyst
- Engineering Assistant
- Technical Attendant
- Junior Operator
- Junior Engineer
- Officer and Engineer grades — some through GATE
These are advertised separately, on their own cycles, with written tests — unlike the merit-based apprentice engagement.
They are the destination. The apprenticeship is not a route into them automatically — but the experience, and the completion certificate, are what a candidate carries into those applications.
Monitor iocl.com’s Careers section for both tracks. They do not appear together.
9. Assessment
In favour:
- 1,524 vacancies live, across four refineries, with more at Haldia, Panipat, Guwahati and Digboi
- No written examination — selection purely on qualifying marks
- No application fee
- ITI candidates need only a pass class — no percentage bar
- B.E./B.Tech, MBA, MCA, CA and LLB holders are excluded — which removes the degree-holding field
- Lateral-entry diploma holders are eligible
- Experience at a Maharatna PSU refinery, and a completion certificate that RRB accepts as a qualification
- Tie-break favours the older candidate
Against:
- No guarantee of permanent employment. IOCL says so directly
- Age 18 to 24 — the narrowest band in this series
- 12 months only
- Two-step application — missing either step means rejection
- Refinery-wise notifications with different dates — no single national window
- The Principal’s certificate and CGPA conversion formula take time to obtain
- Vacancy concentration is uneven — 310 seats in one discipline, a single seat in another
Recommendations:
If you hold an ITI, apply. You need only a pass class, there is no fee, no examination, and the B.Tech population is excluded from competing with you.
Complete both application steps. NAPS or NATS registration is not an application to IOCL. The Microsoft Form is the second half, and missing it is a rejection.
Read the code-wise vacancy table before selecting a discipline. Chemical carried 310 of 582 seats at Paradip; Accountant carried one.
Obtain the Principal’s certificate and the CGPA conversion formula now, not at document verification.
And treat the apprenticeship for what it is — 12 months of refinery experience and a certificate, which feed the permanent IOCL posts, the RRB Technician Grade III route, and the wider PSU technical market. Not a job. A qualification.
Frequently Asked Questions
Q1. Can a B.Tech holder apply for the IOCL apprenticeship? No. “Candidates possessing higher professional degrees like B.E./B.Tech, MBA, MCA, CA or LLB are not eligible to apply for these positions.”
Q2. What is the qualification for IOCL Trade Apprentice? It varies by discipline. Fitter (Mechanical): Matriculation + a 2-year ITI in Fitter trade, NCVT/SCVT recognised, pass class. Attendant Operator (Chemical Plant) and Boiler: a 3-year B.Sc in Maths, Physics, Chemistry or Industrial Chemistry. Technician Apprentice: a 3-year Diploma in the relevant engineering stream.
Q3. Is there a written exam? No. Selection is entirely on the percentage of marks secured in the prescribed qualification, followed by Document Verification and a Pre-Engagement Medical Examination.
Q4. What are the minimum marks? 50% aggregate — 45% for SC/ST/PwBD candidates against reserved seats. ITI qualification requires pass class only.
Q5. How do I apply? Two mandatory steps. Step I: register on NAPS (Trade Apprentices) or NATS (Technician and Graduate Apprentices). Step II: apply against the IOCL notification through the Microsoft Forms link on the IOCL website. Missing either step results in rejection. There is no application fee.
Q6. Does the apprenticeship lead to a permanent IOCL job? No. IOCL states that “apprenticeship is a training-based engagement and does not guarantee permanent employment after completion.” IOCL recruits separately to permanent posts such as Junior Engineering Assistant, Junior Quality Control Analyst, Technical Attendant and Junior Operator, through their own notifications with written tests.
Q7. What is the age limit? 18 to 24 years as on the date specified in the notification. Relaxation: OBC (NCL) +3, SC/ST +5, PwBD +10, PwBD–SC/ST +15.
Q8. What happens if two candidates have the same marks? The candidate with the earlier date of birth — the older candidate — is preferred. If dates of birth are also the same, the candidate with higher Matriculation marks is considered.
Disclaimer: This article is for general information only. IOCL issues separate apprentice notifications for each refinery, with their own advertisement numbers, vacancy counts, disciplines and dates; figures and dates cited are from specific 2026 notifications and are not applicable across all locations. Apprenticeship under the Apprentices Act is a training engagement and does not guarantee permanent employment. Permanent posts are recruited separately. Candidates must read the official notification for their chosen refinery on iocl.com before applying and treat it as the final authority.
