Bihar Police Constable 2026 – CSBC Recruitment Guide

Bihar Police Constable recruitment is one of the state's highest-volume government job opportunities, consistently attracting millions of applicants. The Central Selection Board of Constables (CSBC) conducts recruitment across multiple constable categories including general district police, special branch, radio operators (Constable Operator), jail warders, and prohibition constables. Each category has specific eligibility requirements, exam patterns, and selection criteria.

The 2026 recruitment cycle is particularly active with multiple CSBC notifications: 83 Special Branch Constables (written exam is the merit-determining stage — unique among Bihar Police recruitments) and 993 Constable Operators (Class 12 PCM required, written exam + PET). The horizontal reservation of 35% for women candidates applies across categories.

CSBC also released notification for Special Branch Constables (83 posts, Advt. 01/2026) with applications from February 6 to March 5, 2026. The Special Branch exam pattern is unique — two written papers (Paper 1: Reasoning + English + Hindi; Paper 2: GS + Maths + Bihar GK) with merit based 100% on written exam, unlike other constable posts where PET determines merit.

Constable Operator (993 posts): Written Exam (100 marks, OMR-based) covering GK/Current Affairs, Physics, Chemistry, and Mathematics at Intermediate level. –0.25 negative marking per wrong answer. Qualifying marks: 50% (General), 45% (SC/ST). After written exam: PET (qualifying only — 1-mile run for males in 6 minutes, 1-km for females), then Document Verification and Medical.

Special Branch Constable (83 posts): Two written papers of 100 marks each (90 minutes each). Paper 1: Reasoning & Analytical Ability (50) + English Grammar/Comprehension (30) + Hindi Grammar (20). Paper 2: General Studies & Current Affairs (50) + Maths & QA (30) + Bihar GK (20). –0.25 negative marking. Merit is 100% written exam-based.

Domicile

Candidates must be original inhabitants of Bihar (Mul Niwasi). Domicile proof is required at the document verification stage.

• Bihar GK Is High-Value Especially for Special Branch: Bihar-specific GK (Bihar History — Mauryan Empire, Magadha, modern Bihar freedom movement), Bihar geography (major rivers: Ganga, Gandak, Kosi, Sone; districts), Bihar government schemes, and famous Bihar personalities carry high marks in Special Branch Paper 2. Prepare a dedicated Bihar GK module.
• PCM at Class 12 Level for Constable Operator: Constable Operator requires Physics, Chemistry, and Maths at Class 12 level — significantly more technical than regular constable posts. If you're a PCM student, this is an easier exam; if not, you'll need to prepare these subjects from scratch.
• Special Branch Written Exam Determines 100% Merit: Special Branch Constable is unique — there is no PET-based merit scoring. The written exam is the ONLY merit-determining stage (PET is only qualifying). This means a strong written exam performance with high accuracy gives a clear advantage.
• ₹100 Fee For All Categories — Apply Without Hesitation: CSBC Bihar has a uniform ₹100 application fee for all categories (General, OBC, SC, ST). There is no fee waiver but also no differential pricing. The low fee makes it financially accessible to apply as soon as eligible.

Solving previous year question papers is the single most effective exam preparation strategy for Bihar Police Constable 2026. Past papers reveal question patterns, recurring topics, and difficulty level. Solve 3–5 years of papers to gain a measurable advantage in accuracy and time management.
