Important Rule for Candidates Who Have Already Completed an Apprenticeship
Candidates who have previously completed apprenticeship training must also satisfy the conditions mentioned in the IOCL Recruitment 2026 notification.
Generally, there must be a minimum gap of one year from the completion of the previous apprenticeship as of the eligibility cut-off date.
However, certain exceptions apply. If the previous apprenticeship contract was terminated because of the employer’s failure, no waiting period is required.
Candidates whose previous apprenticeship was terminated by themselves because of circumstances such as health or financial hardship, relocation, transportation difficulties, career change or language barriers may apply after a minimum gap of three months. The notification states that there is no waiting period for women candidates in this particular situation.
Candidates applying for apprenticeship training for a second time must submit the prescribed affidavit during document verification if selected.
How Will Selection Take Place in IOCL Recruitment 2026?
One of the most important features of IOCL Recruitment 2026 is the selection process.
No Written Examination
IOCL has clearly stated that there will be no written test for these apprenticeship vacancies.
Instead, eligible candidates will be shortlisted on the basis of their academic performance. The merit list will be prepared according to the percentage of marks obtained in the prescribed qualification, with candidates ranked in descending order of marks.
IOCL will consider the aggregate marks of all subjects and all years or semesters of the prescribed qualification.
Preference will be given to candidates who are undertaking apprenticeship training for the first time.
Tie-Breaking Rule
If two or more candidates obtain the same percentage of marks, the candidate who is older in age will receive preference in the merit ranking.
If the candidates also have the same date of birth, the candidate with the higher percentage of marks in Class 10 will be considered higher in the merit list.
Candidates shortlisted on the basis of merit will subsequently be called for:
- Document Verification
- Pre-Engagement Medical Examination
- Final engagement, subject to fulfilling all applicable conditions
Only candidates whose documents are verified and who are declared medically fit will receive the offer of engagement.
Documents Required for IOCL Recruitment 2026
Candidates shortlisted for document verification must bring the original documents along with self-attested copies.
The important documents include:
- Class 10 marksheet/certificate as proof of date of birth
- Class 12 marksheet
- Semester-wise or year-wise marksheets of graduation/diploma
- Graduation or diploma certificate
- CGPA/OGPA/letter-grade conversion certificate, wherever applicable
- Certificate mentioning the date of publication of the qualifying examination result, wherever required
- SC/ST certificate, if applicable
- OBC (NCL) certificate and required declaration, if applicable
- EWS Income and Asset Certificate, if applicable
- PwBD/Disability certificate, if applicable
- NAPS/NATS registration details or printout
- Prescribed affidavit regarding apprenticeship eligibility, where applicable
- Any other certificate or document specified by IOCL
- Original photo identity proof
Accepted photo ID documents include Aadhaar Card, PAN Card, Voter ID, Driving Licence or Passport.
Candidates should carefully check all documents before submitting their application because candidature can be cancelled if incorrect, false or misleading information is discovered at any stage.
How to Apply for IOCL Recruitment 2026?
Candidates who meet the eligibility requirements can apply online for IOCL Recruitment 2026 by completing the required registration and application steps.
The application process involves two important stages.
Step 1: Register on NAPS/NATS
Candidates must have an active Apprentice Registration/Enrolment Number on the relevant apprenticeship portal.
For Post Codes 101 and 103, candidates are required to register on the NAPS portal and apply for the relevant apprenticeship opportunity at Bongaigaon Refinery.
For Post Code 107, candidates must register on the NATS portal and apply for the relevant IOCL Bongaigaon Refinery opportunity through their dashboard.
Candidates should make sure that their profile information on the respective portal is complete and accurate before submitting the application.
Step 2: Fill the Mandatory Microsoft Form
After applying through the relevant NAPS/NATS portal, candidates must complete the additional information form provided by IOCL.
This Microsoft Form is a mandatory part of the application process. Simply registering on NAPS or NATS does not complete the application.
Candidates should therefore complete both stages before the deadline.
Step 3: Check the Details Carefully
Before final submission, candidates should carefully verify:
- Personal information
- Educational qualifications
- Category details
- Contact information
- Apprenticeship registration details
- Marks and percentage
- Trade/discipline selected
A candidate can apply for only one trade/discipline under this recruitment. Candidates applying for more than one trade or discipline may have their applications rejected.
