RRB Group D Syllabus

The RRB Group D examination 2027 is one of the largest recruitment drives conducted by the Railway Recruitment Boards for Level 1 posts in Indian Railways. Group D posts include Track Maintainer Grade IV, Helper/Assistant in various departments (Electrical, Mechanical, Signal & Telecommunication, Engineering, Operations & Business Development), Hospital Attendant, Gateman, and other similar positions that form the operational backbone of the railway network.

The minimum qualification for Group D is 10th pass (Matriculation) from a recognised board, or an ITI (Industrial Training Institute) certificate from a recognised institute in the relevant trade. The selection process consists of a single Computer Based Test (CBT) followed by a Physical Efficiency Test (PET) and Document Verification and Medical Examination.

Quick Facts: RRB Group D 2027

RRB Group D Selection Process 2027

•        Stage 1: Computer Based Test (CBT) -- 100 questions, 100 marks, 90 minutes; covers Mathematics, GI&R, General Science, and General Awareness

•        Stage 2: Physical Efficiency Test (PET) -- Conducted for candidates shortlisted from CBT (approx. 3 times the vacancy count); no marks awarded; qualifying in nature

•        Stage 3: Document Verification (DV) -- Verification of original certificates of shortlisted candidates

•        Stage 4: Medical Examination -- Candidates must meet prescribed medical standards for the applied post

Note: PET is qualifying in nature only. The merit list for final selection is prepared based on CBT marks only, subject to clearing PET, DV, and medical.

Preparation Tips for RRB Group D 2027

1. Focus on General Science and Reasoning

Together, General Science (25) and Reasoning (30) account for 55 out of 100 marks in Group D CBT. These are the highest-scoring sections for well-prepared candidates. General Science at Class 10 level is highly accessible to most candidates who revise NCERT Science thoroughly.

2. Start PET Preparation Alongside CBT

The Physical Efficiency Test (PET) is a physically demanding qualifying stage and must not be left until after CBT results. Begin physical training for the 1000m run (men) or 400m run (women) and the 35 kg / 20 kg weight carrying task from the beginning of your preparation.

3. Prioritise Railways GK in General Awareness

Given that Group D is a railway department post, Indian Railways GK questions appear frequently in the GA section. Prepare a dedicated Railways GK notes sheet covering zones, train types, safety systems, major projects, and railway firsts.

Frequently Asked Questions: Group D

Q1. Is Group D a technical or non-technical post?

Group D posts are generally semi-skilled or unskilled Level 1 posts, most of which do not require a technical degree. However, some posts (Helper in technical departments) may require an ITI certificate in a relevant trade. Candidates should check the specific post requirements in the official notification.

Q2. What is the pay scale for Group D posts?

Group D posts are Level 1 posts in the 7th CPC Pay Matrix, with a basic pay of Rs. 18,000 per month plus applicable allowances (HRA, DA, Transport Allowance, etc.).

Q3. Is Group D CBT score used in the final merit list?

Yes. The CBT score is the sole basis for the final merit list, provided the candidate has cleared the PET, DV, and medical examination stages. PET is qualifying only and does not add marks.
