Key qualification rules:
- Only regular full-time courses from recognized Boards/Universities/Institutes are accepted — part-time, correspondence, or distance-mode qualifications are not eligible.
- Diploma/Graduation/ITI must be in the exact specified branch/subject; other branches are rejected.
- Candidates with BE/B.Tech, MBA, CA, LLB, MCA or equivalent higher qualifications are not eligible, even if pursuing and completed before joining.
- B.Sc (PCM/Industrial Chemistry) candidates can apply to only one of codes 101, 103, or 108. B.Com holders can apply to only one of codes 108 or 109.
- Candidates applying to more than one trade/discipline will be summarily rejected.
This qualification matrix makes it easy for candidates to instantly check which IOCL apprentice trade matches their degree or diploma before applying.
📉 Minimum Qualifying Marks
| Category | Minimum Aggregate Marks |
|---|---|
| General / EWS / OBC(NCL) | 50% |
| SC / ST / PwBD (on reserved seats) | 45% |
- CGPA/OGPA/Letter Grade must be converted to equivalent percentage as per the issuing Board/University norms, and a conversion certificate must be submitted at Document Verification.
- For ITI trades, only pass marks are required (no minimum percentage threshold).
- Minimum qualifying marks are relaxed by 5% for SC/ST/PwBD candidates against reserved positions.
Since there’s no written exam, your qualifying degree/diploma percentage directly decides your merit rank — so these cutoff marks matter more than in most other government jobs.
🎂 Age Limit
As on 30 June 2026 (cut-off date for all 4 refineries):
- Minimum Age: 18 years
- Maximum Age: 24 years (General/EWS)
Age Relaxation (on reserved seats):
| Category | Relaxation |
|---|---|
| SC/ST | 5 years |
| OBC (NCL) | 3 years |
| PwBD | 10 years (irrespective of seat reservation) |
| PwBD + SC/ST | 5 years additional |
| PwBD + OBC(NCL) | 3 years additional |
Only the Matriculation (Class X) certificate is accepted as proof of date of birth — no other document will be considered.
💰 Application Fee
There has been no fee mentioned by IOCL in all the four notifications. The process of engagement at IOCL is completely free through the portals of NAPS/NATS and Microsoft Forms. (It is advised to always refer to the official notification to avoid any fraudulent claims of fee payment.)
⚙️ Selection Process
There is NO Written Test / CBT / Interview for any of these four IOCL apprentice posts. Selection is purely:
- Merit List based on percentage of marks (aggregate of all years/semesters) in the qualifying examination.
- Tie-breaker: older date of birth wins; if still tied, higher Matriculation percentage decides.
- Document Verification of shortlisted candidates.
- Pre-Engagement Medical Fitness examination.
- Offer of Engagement to candidates clearing both DV and medical fitness.
Preference is given to first-time apprentices over those repeating apprenticeship in a different trade. This no-exam process means your academic percentage is everything — there’s no second chance to “perform better” on exam day.
📚 Examination Syllabus
Not Applicable – Due to lack of an examination paper, there is no syllabus provided by IOCL for these positions of apprenticeship. There is no exam at all in the selection process, hence only your percentage matters here.
📅 Important Dates (Same for All 4 Refineries)
| Event | Date |
|---|---|
| Online Application Opens (NAPS/NATS + MS Forms) | 29 June 2026, 10:00 hrs |
| Last Date to Apply | 28 July 2026, 17:00 hrs |
| Tentative DV Candidate List Publication | 5 August 2026 |
| Tentative Document Verification | 11–18 August 2026 |
With just one month between opening and closing date, candidates should not wait till the last day — portal congestion near the deadline is common in large PSU recruitment drives like this.
📝 How to Apply (2-Step Process — Mandatory for All Refineries)
STEP 1 — Register & Apply on NAPS or NATS Portal:
- For Codes 101, 102, 103, 108, 109, 110, 111 → Register on NAPS portal: https://apprenticeshipindia.gov.in/
- For Codes 104, 105, 106, 107 → Register on NATS / BOAT portal: https://nats.education.gov.in
- Search for the relevant IOCL Refinery Unit location and select your trade.
- Log in and apply using the refinery’s Establishment ID:
| Refinery | NATS Establishment ID | NAPS Establishment ID |
|---|---|---|
| Bongaigaon | EASCHC000001 | E07191800001 |
| Gujarat | WGJVDS000002 | E03202408538 |
| Mathura | NUPMTC000001 | E12150900008 |
| Paradip | EORJSC000003 | E07192100001 |
STEP 2 — Fill the Microsoft Form (Mandatory):
- After applying on NAPS/NATS, visit www.iocl.com and fill the refinery-specific Microsoft Form (links given on the official site / notification).
- Submit only one response per Microsoft Form.
- Ensure your Enrolment No./Student ID/Application Code matches exactly across both Step 1 and Step 2.
Both steps are compulsory — completing only one step makes your application “Invalid” and it will be summarily rejected. This two-step process trips up a lot of first-time applicants, so cross-check your details carefully before final submission.
📜 General Conditions
- Candidates must already possess the prescribed qualification — those awaiting results cannot apply.
- Only one application per trade/discipline is allowed; multiple trade applications get rejected outright.
- No employment obligation arises after apprenticeship completion — IOCL clearly states apprentices cannot claim regular job rights.
- Furnishing false/incorrect information at any stage leads to cancellation of candidature and possible criminal prosecution.
- Original Photo ID (Aadhaar/PAN/Voter ID/DL/Passport) is mandatory at Document Verification.
- Disputes are subject to the local court jurisdiction of the respective refinery location (Chirang for Bongaigaon, Vadodara for Gujarat, Mathura for Mathura, and the court near Paradip for Paradip).
- IOCL has issued a fraud warning — rely only on www.iocl.com for genuine updates; do not trust job ads circulated via email/social media.
These conditions are strict, and even small mismatches between your NAPS/NATS and Microsoft Form data can get your application rejected — so accuracy is non-negotiable here.

There are 1524 total apprentice vacancies combined — 144 at Bongaigaon, 647 at Gujarat, 151 at Mathura, and 582 at Paradip Refinery.
