Is This Recruitment Right for You?
- Science/Commerce Graduates: If you have completed B.Sc or B.Com and are under 24 years of age (or within relaxation limit), you are eligible for technical apprentice, accountant, or secretarial roles.
- Diploma Holders: Candidates holding a Diploma in Mechanical, Chemical, Electrical, or Instrumentation Engineering can apply for corresponding Technician Apprentice roles within 12 months of qualification.
- ITI/Class XII Pass Candidates: School leavers with Class XII or ITI certifications qualify for Data Entry Operator and Fitter trades; ITI completion in the Fitter Trade specifically opens the mechanical fitter apprenticeship path.
- Candidates with Relevant Age & Marksheet: Aggregate marks of 50% (45% for SC/ST/PwBD) in the prescribed qualification are required; candidates still awaiting final results cannot apply.
- Reserved Category Candidates: SC/ST/OBC (NCL) candidates enjoy age relaxation as listed above and apply against reserved seats with adjusted qualifying marks.
About the Apprentice Role
Apprentices at IOCL Barauni Refinery gain hands-on training in petroleum refining, mechanical maintenance, chemical processing, or administrative functions, depending on their trade. Roles such as Attendant Operator involve shift-based operations in hazardous process areas, requiring strong technical understanding and adherence to safety protocols. The apprenticeship spans 12-24 months, depending on the trade, during which candidates work under supervision, rotate through different departments, and learn industry-standard practices under the Apprentices Act framework. Upon completion of training and medical fitness certification, candidates may transition to permanent roles if vacancies exist, though IOCL explicitly states that no employment guarantee is extended solely for completing an apprenticeship.
Apprentice Stipend and Benefits
| Benefit | Details |
|---|---|
| Monthly Stipend | As per the Apprentices Act 1961/1973 and the Apprentices Rules 1992 |
| PPE (Codes 101-107) | One pair of safety shoes and one helmet (returnable after training) |
| General Leave | 32 days per annum (8 days per quarter) |
| Casual Leave | 12 days per calendar year (pro-rata for partial year) |
| Accident Insurance | Coverage provided under statutory norms |
| Accommodation | Not provided |
| HRA/Allowances | Not applicable during apprenticeship |
The stipend amount varies based on the Apprentices Act guidelines and is not a fixed flat sum; candidates should verify the exact stipend schedule on the IOCL website or from the refinery HR department. IOCL has explicitly clarified that completion of apprenticeship training does not confer any automatic right to regular employment.
Selection Process
The IOCL Barauni Apprentice selection process is merit-based with no written examination. Candidates are ranked by their aggregate percentage of marks in the prescribed qualification (all years/semesters combined) in descending order. First-time apprenticeship applicants receive preference in tie-breaking situations.
Merit Listing and Tie-Breaking
Merit is determined by the total aggregate percentage scored in the qualifying examination. If two candidates have identical aggregate marks, the candidate senior in age (older date of birth) is ranked higher. If dates of birth also match, the candidate with higher Class X/Matriculation marks is ranked higher.
Document Verification
Shortlisted candidates-identified from the merit list on 05/08/2026-are called for document verification between 11/08/2026 and 18/08/2026. All original documents and self-attested photocopies must be brought to the verification centre. Missing or incorrect documents result in summary rejection.
Pre-Engagement Medical Fitness
Candidates shortlisted after document verification undergo pre-engagement medical examination as per Apprentices Act standards. Only those declared medically fit proceed to the engagement offer stage.
Final Engagement
An offer of engagement is issued to candidates whose documents are verified as correct and who have obtained medical fitness clearance from the appointed medical examiner.

Common Mistakes to Avoid While Applying for the IOCL Barauni Apprentice 2026
- Skipping the Microsoft Form submission: Registering only on NAPS/NATS without filling out the mandatory Microsoft Form results in an incomplete application and automatic rejection. Both steps must be completed.
- Applying for multiple trades: Candidates who submit applications for more than one trade or discipline will have all applications summarily rejected without refund or appeal opportunity.
- Mismatched details between portals: Enrolment numbers, registration numbers, personal details, and educational qualifications must match exactly between NAPS/NATS and the Microsoft Form. Any discrepancy leads to rejection at document verification.
- Using invalid contact information: If your email or mobile number becomes inactive before document verification or engagement offer, you will miss all official communications and forfeit your position.
- Missing CGPA conversion certificates: Candidates whose qualifications use CGPA/OGPA grading must obtain an official percentage conversion certificate from their institute before document verification. Absence of this document at verification results in immediate rejection.
- Applying with pending qualification results: Candidates whose final exam results were not declared as of 30/06/2026 are ineligible. Do not apply if you are awaiting result announcements.
