IOCL Bongaigaon Apprenticeship 2026: 144 Seats Across 11 Trades, Apply by July 28

Your Chance to Join India's Largest Oil Refiner as an Apprentice

If you're fresh out of school or college and looking to build real skills in India's energy sector,​ Indian Oil Corporation Limited (IOCL),​ Bongaigaon has just opened 144 apprenticeship seats. This isn't a typical entry-level job posting. IOCL is a Fortune Global 500 company,​ and a placement here on your resume carries weight. The refinery is offering structured apprenticeships across 11 different trades and disciplines,​ each with its own training timeline and career path.

What makes this opportunity stand out? The selection process is merit-based with zero written exam. You don't study for weeks hoping to crack a test. Instead,​ IOCL ranks candidates by their academic performance in the prescribed qualification. If you've done well in your board exams or college,​ you have a genuine shot. You'll also receive a monthly stipend,​ 32 days of general leave annually,​ accident insurance,​ and safety gear for plant-based roles. No hidden costs. No surprise deductions.

But here's what you need to know upfront: this is an apprenticeship contract,​ not a permanent job offer. After training ends,​ IOCL has no obligation to hire you as a full-time employee. That said,​ completing an apprenticeship at a Fortune 500 refinery opens doors elsewhere in the industry and beyond.

Breaking Down the 11 Apprenticeship Codes

Indian Oil Corporation Limited (IOCL),​ Bongaigaon has structured this recruitment into 11 distinct apprenticeship codes,​ each targeting a specific trade or discipline. Let's walk through what each one offers so you can identify which fits your background.

Graduate-Level Apprenticeships (B.Sc. Required)

Code 101: Trade Apprentice–Attendant Operator (Chemical Plant) is the largest intake with 43 seats. You need a three-year B.Sc. in Mathematics,​ Physics,​ Chemistry,​ or Industrial Chemistry with at least 50% marks (45% for SC/​ST/​PwBD). The training lasts 12 months. This role involves hands-on work in chemical plant operations at the refinery.

Code 103: Trade Apprentice (Boiler) offers 14 seats for B.Sc. graduates with the same subject requirements. Training runs for 24 months,​ the longest in this batch. Boiler operation is a specialized technical skill crucial to refinery operations.

Important note: if you have a B.Sc.,​ you can apply to only one of codes 101,​ 103,​ or 108 (the Trade Apprentice Secretarial Assistant,​ which also requires a degree). Applying to more than one will result in automatic rejection.

Diploma-Level Technician Apprenticeships

If you've completed a three-year diploma,​ Indian Oil Corporation Limited (IOCL),​ Bongaigaon has four technician apprenticeship codes tailored for you.

Code 104: Technician Apprentice (Chemical) requires a Diploma in Chemical Engineering,​ Petrochemical Engineering,​ Chemical Technology,​ or Refinery and Petrochemical Engineering. It offers 14 seats with a 12-month training period.

Code 105: Technician Apprentice (Mechanical) is the second-largest intake at 20 seats. You need a three-year Diploma in Mechanical Engineering. Training lasts 12 months. This code also includes 2 PwBD (Persons with Benchmark Disabilities) seats.

Code 106: Technician Apprentice (Electrical) requires a Diploma in Electrical Engineering or Electrical and Electronics Engineering. It offers 15 seats with 1 PwBD seat reserved. Training is 12 months.

Code 107: Technician Apprentice (Instrumentation) is more specialized,​ with only 9 seats. You need a Diploma in Instrumentation Engineering,​ Instrumentation and Electronics,​ Instrumentation and Control Engineering,​ or Applied Electronics and Instrumentation Engineering. Training runs 12 months.

ITI Trade Apprenticeship

Code 102: Trade Apprentice (Fitter) is the only ITI-based code here,​ offering just 6 seats. You need Matriculation (Class X pass) plus an ITI in Fitter Trade of at least two years' duration with a pass grade. The training period is 12 months. Notably,​ ITI qualifications only need a pass grade,​ not the 50% marks required for degrees and diplomas.

Commerce and Administrative Roles

Code 108: Trade Apprentice Secretarial Assistant opens to B.A.,​ B.Sc.,​ or B.Com. graduates. It offers 15 seats with a 15-month training period. This is the only administrative code in the batch.

Code 109: Trade Apprentice Accountant requires a three-year B.Com. degree. Only 1 seat is available. Training runs 12 months. If you're a B.Com. graduate,​ you can apply to either code 108 or 109,​ but not both.

Data Entry Operator Roles (Two Pathways)

Code 110: Trade Apprentice Data Entry Operator (Fresher Apprentices) requires only Class XII pass. It offers 5 seats with a 12-month training period. This is one of the lowest eligibility thresholds in the batch.

Code 111: Trade Apprentice Data Entry Operator (Skill Certificate Holders) also requires Class XII pass but adds a requirement: a Skill Certificate in Domestic Data Entry Operator from an NSQF-recognized awarding body. Only 2 seats are available. Training is 12 months.

The 144 total seats are distributed across these 11 codes. Code 101 alone accounts for nearly 30% of the intake,​ making it the most competitive. Codes 109 and 111 have very limited seats,​ so your chances depend heavily on how many other qualified candidates apply.

Important Dates and Application Timeline

You have exactly 29 days to apply. That sounds like plenty of time,​ but don't procrastinate. The portals can get slow in the final days,​ and submission errors happen. Aim to complete both application steps by mid-July.

Merit-Based Selection: How You Get Shortlisted

Here's the best part: there's no written exam. Indian Oil Corporation Limited (IOCL),​ Bongaigaon selects apprentices purely on academic merit. The ranking is based on the percentage of marks in your prescribed qualification in descending order. So if you scored 75% in your B.Sc. and another candidate scored 72%,​ you rank higher.

Tiebreakers matter. If two candidates have the same percentage,​ IOCL gives preference to first-time applicants (those who haven't applied to IOCL apprenticeships before). If that's still tied,​ seniority of age (older candidate wins) is the next tiebreaker. If still tied,​ higher Matriculation marks decide the winner.

This system is transparent and fair. You don't need to study for months or guess what IOCL wants. Your board exam performance is what counts. If you've scored well,​ your chances are solid.

How to Apply: Two-Step Process

The application has two mandatory steps,​ and you must complete both between 29 June and 28 July 2026.

Step I: NAPS or NATS Portal Registration

Your first step depends on which code you're applying for. Codes 101,​ 102,​ 103,​ 108,​ 109,​ 110,​ and 111 use the NAPS (National Apprenticeship Promotion Scheme) portal. Codes 104,​ 105,​ 106,​ and 107 use the NATS (National Apprenticeship Training Scheme) portal.

When registering,​ you'll need to enter the correct Establishment ID for IOCL Bongaigaon:

• For NAPS: E07191800001
• For NATS: EASCHC000001

Use the wrong ID,​ and your application won't link to IOCL Bongaigaon. Register on the appropriate portal,​ fill in your details,​ upload required documents (as specified by the portal),​ and complete the registration.

Step II: Microsoft Form Submission

After NAPS or NATS registration,​ you must submit additional details on a Microsoft Form accessible through www.iocl.com. This form collects information the portal doesn't capture. Both steps must be completed within the same 29-day window. Completing only one step disqualifies you.

Document Verification and Medical Fitness

After the application window closes,​ IOCL publishes a tentative list of shortlisted candidates on 5 August 2026. If your name is on it,​ you'll be called for document verification between 11 and 18 August 2026. Bring originals of:

• Matriculation certificate
• Qualification marksheets and certificates (B.Sc.,​ B.Com.,​ Diploma,​ ITI,​ or Class XII as applicable)
• CGPA conversion certificates (if applicable)
• Caste or category certificate (SC,​ ST,​ OBC,​ EWS,​ or PwBD as applicable)
• NAPS or NATS registration printout

After document verification,​ you'll undergo a pre-engagement medical fitness examination. Only candidates medically fit are issued offers of engagement. The medical check is standard for refinery roles because the work involves hazardous environments.

Age Limit and Relaxations

Your age must be between 18 and 24 years as on 30 June 2026 for General and EWS categories. Reserved categories get relaxations:

The relaxations are combinable for PwBD candidates. If you're a PwBD candidate from the SC category,​ you get both the 5-year SC relaxation and the 10-year PwBD relaxation,​ totaling 15 years extra.

Category-Wise Seat Distribution

All 144 seats are reserved across six categories. Here's the breakdown:

PwBD is a horizontal reservation,​ meaning the 5 seats come from the above categories,​ not in addition to them. If you belong to SC,​ ST,​ or OBC-NCL and also have a benchmark disability,​ you may get additional age relaxation. We'll cover that in the eligibility section below.

Why This Opportunity Matters

A Fortune Global 500 company like IOCL doesn't recruit apprentices casually. This is structured,​ professional training at one of India's largest refineries. You'll gain hands-on experience in chemical plants,​ mechanical systems,​ electrical grids,​ or administrative work depending on your code. You'll work alongside experienced professionals in a regulated,​ safety-conscious environment.

The merit-based selection also means your hard work in school or college directly translates to your chances. No coaching required,​ no exam strategy needed. Your marks speak for themselves.

Plus,​ the stipend,​ leave,​ and insurance provide financial stability during training. For candidates from modest backgrounds,​ this is meaningful support.
