Overview

BARC OCES/DGFS recruits engineering and science graduates into India's Department of Atomic Energy network through the BARC Training School — a rigorous one-year orientation programme covering nuclear science, engineering fundamentals and specialised coursework, before trainees are posted into BARC, NPCIL, or other DAE constituent units. Selection for engineering disciplines primarily uses GATE scores (or a BARC-specific written test, depending on the discipline and cycle), followed by a Personal Interview. The programme is highly selective and academically demanding, reflecting the specialised, research-intensive nature of India's atomic energy sector.

What's New in the 2026 Cycle

What changed in the 2026 cycle

  • OCES (for engineering/science graduates) and DGFS (a fellowship scheme integrated with select IITs for select disciplines) are the two primary entry routes into the BARC Training School.
  • GATE score is commonly used for engineering-discipline shortlisting, though BARC may also conduct its own written test depending on the specific discipline and cycle.
  • The one-year BARC Training School programme itself is intensive, combining coursework with practical/lab components before final placement.
  • Selected candidates may be posted to BARC, NPCIL or other DAE units based on training performance and organisational requirements.

BARC OCES/DGFS Detailed Subject-Wise Syllabus

Below is the complete topic-wise BARC OCES/DGFS syllabus for every subject tested across all stages, with a short note on what each section actually rewards — use this to build a section-wise study plan rather than relying on generic topic summaries.

1

GATE Score / Academic Record (discipline-specific)

Given the programme's selectivity, both a strong GATE score and a consistently strong academic record matter — this isn't a single-test gateway.

  • Refer to the GATE syllabus for your specific engineering discipline, or your MSc-level Physics/Chemistry coursework for science-stream applicants
2

BARC Training School Curriculum (post-selection, not examined at entry)

Understanding this curriculum's demands helps you demonstrate genuine readiness during the Interview stage.

  • Nuclear physics & reactor theory fundamentals
  • Radiation safety & protection
  • Discipline-specific advanced engineering/science coursework
  • Practical/laboratory components relevant to atomic energy applications

Selection Process

  1. Shortlisting based on academic record and/or GATE score, depending on the discipline and cycle.
  2. Personal Interview.
  3. Selection into the one-year BARC Training School programme.
  4. Final placement into BARC, NPCIL or other DAE units based on training performance and organisational requirements.

Salary & Job Profile

During the one-year Training School programme, trainees receive a fixed stipend; on successful completion, they're absorbed as Scientific Officers starting at Pay Level 10 (₹56,100 basic) of the 7th CPC matrix, plus Dearness Allowance, HRA and DAE-specific research allowances.
