Who Cannot Apply
BE/B.Tech, MBA, CA, LLB or MCA holders (or those pursuing one, completing it on or before joining); engineering graduates/diploma/vocational holders with 1 or more years of job experience after the qualification; candidates who completed 5 years since acquiring the prescribed qualification as on 30.11.2026. Earlier apprenticeship is allowed in a different trade/discipline only after a gap of at least 1 year from completion (with exceptions). More than one trade/discipline leads to applications being summarily rejected. Preference is given to first-time apprentices; an Annexure-A affidavit is needed at Document Verification.
Stipend and Benefits
This is apprenticeship training, not regular employment — a monthly stipend is paid as per the Apprentices Act/Rules and Corporation guidelines; no amount is stated in the notification.
- Leave: 32 days of General Leave per calendar year (8 per quarter, covering medical grounds) + 12 days of Casual Leave per calendar year pro-rata, plus establishment holidays; leave not availed lapses at the end of the apprenticeship.
- PPE: one pair of safety shoes + helmet for codes 101/103/105/107 (returnable).
- Accident insurance for all apprentices.
- DV travel: SC/ST/PwBD candidates are reimbursed a single second-class railway fare from the nearest station and back on production of tickets, where the distance is at least 30 km.
- No HRA or company accommodation.
- No obligation of employment after the apprenticeship; training may be extended under Rule 7 of the Apprentices Rules 1992.
Selection Process
- Merit List — percentage of marks in descending order in the prescribed qualification (aggregate of all subjects of all years/semesters); first-time apprentices get preference; in case of a tie, the senior candidate by date of birth comes first, then the higher percentage in Matriculation (Class X).
- Document Verification — shortlisted by merit and seats per trade; bring originals + a self-attested copy of: 10th/Matriculation certificate (proof of date of birth); CGPA/OGPA/letter-grade conversion certificate if applicable; Principal’s certificate (result publication date if not on the marksheet, regular full-time mode, good conduct); SC/ST/Disability/OBC (NCL) certificate with Declaration or EWS Income and Asset Certificate in the prescribed format; print of NATS/NAPS registration; Annexure-A affidavit; one original Photo ID (Aadhaar, PAN, Voter ID, Driving Licence or Passport).
- Pre-Engagement Medical Fitness — only candidates declared fit under the minimum physical fitness standards of the Apprentices Act are considered; finally shortlisted candidates with documents and medical fitness in order get the offer of engagement.
Note: filling of seats is at the management’s discretion; candidature is provisional, subject to certificate verification at every stage. Candidates must declare ailments/abnormalities, any earlier UNFIT finding in a refinery/PSU medical, and any arrest/prosecution/detention/fine/conviction; false information leads to cancellation.
