Educational Qualification Conditions Candidates Must Know
Before applying, candidates should carefully note these qualification-related conditions specified in the official notification:
- Candidates must have already passed the prescribed qualification on the cut-off date (30 June 2026). Those whose results are still awaited are not eligible to apply.
- Minimum 50% aggregate marks required (relaxed to 45% for SC/ST and PwBD candidates against reserved seats).
- Qualification must be from a recognized Board/University/Institute through a regular full-time mode — part-time, correspondence, or distance education qualifications are not accepted.
- For ITI (Fitter) candidates, only courses recognized by NCVET/SCVT in a regular full-time mode are considered.
- Diploma/Graduation/ITI must be in the specific branch/subject mentioned against each trade code; qualifications in unrelated branches will not be considered eligible.
- Candidates holding higher qualifications such as B.E./B.Tech, MBA, CA, LLB, or MCA (completed or in progress, finishing before joining) are not eligible to apply.
- Candidates with one year or more of job experience after acquiring their qualification are not eligible.
- Candidates who completed their prescribed qualification more than 5 years ago (as on the cut-off date) are also not eligible.
- A B.Sc. (Physics, Mathematics, Chemistry/Industrial Chemistry) candidate may apply for only one of Code 101, 103, or 108. Similarly, a B.Com candidate may apply for only one of Code 108 or 109. Applying for multiple trades/disciplines leads to summary rejection of the application.
Selection Process: No Written Examination
Unlike many other PSU apprentice notifications, IOCL Barauni Refinery Apprentice 2026 selection does not involve any written test. Selection is purely merit-based, determined as follows:
- Candidates are ranked by percentage of marks (aggregate of all subjects across all years/semesters) obtained in the qualification prescribed for the trade they applied for.
- Preference is given to candidates applying for apprenticeship training for the first time.
- In case of a tie in percentage, the candidate senior in age (earlier date of birth) is ranked higher. If the date of birth is also the same, the candidate with higher marks in Matriculation is preferred.
- Shortlisted candidates are then called for Document Verification, where original certificates are checked against the submitted application.
This merit-only approach makes it critical for candidates to ensure their percentage/CGPA conversion is accurately filled in the Microsoft Form, since even small calculation errors can affect merit ranking.
How to Apply for IOCL Barauni Refinery Apprentice 2026
The application process for this notification is unusually detailed and involves two mandatory steps. Missing either step means the application will not be considered complete.
Step I: Registration on NAPS or NATS Portal
The portal you register on depends on which trade code you are applying for:
For Codes 101, 102, 103, 108, 109, 110 & 111 — register on the NAPS portal
- Select “Apprenticeship Opportunities” from the top menu
- Search by location for IOCL Barauni Refinery and select the relevant trade
- Complete login and registration with your basic details
For Codes 104, 105, 106 & 107 — register on the NATS portal (Board of Apprenticeship Training)

Use the following Establishment IDs while applying:

After successfully applying through NAPS/NATS, candidates must also submit additional details through the official Microsoft Form titled “Apprenticeship Additional Data Form: Barauni Refinery 2026,” accessible via the IOCL website. Only one response per candidate is allowed.
Important: The application is considered complete only when both Step I and Step II are finished. The Enrollment Number, Student ID, and Registration Number entered must be identical across both steps — any mismatch can lead to rejection of the application.
