Bihar Police Constable Syllabus 2026 – New Exam Pattern, Subject-wise Topics & Physical Standards

The Bihar Police Constable 2026 recruitment — conducted by the Central Selection Board of Constables (CSBC), Bihar — is one of the most anticipated government job openings in the state, with 22,771 posts notified for Bihar Police Constable and 993 posts for the Police Operator vacancy.​​

For lakhs of aspirants from Bihar, Jharkhand, and eastern UP, this is one of the most accessible central-government-equivalent state recruitment drives — with a Class 10 (Matric) level written exam, a clear physical test standard, and no interview or negative marking in the written test.

What most candidates don’t realise until too late: the Bihar Police Constable written exam is qualifying in nature — you need only 30% marks to proceed to the Physical Efficiency Test (PET). But the PET is the real eliminator — underprepared candidates who ignore physical fitness and focus only on the written exam get eliminated at the physical stage after clearing the written one.

This guide covers the complete Bihar Police Constable syllabus, exam pattern, subject-wise topic breakdown, physical standards for PET, and a preparation strategy.

Bihar Police Constable 2026 – Recruitment Overview

Selection Process – All Three Stages

Important rule: The final merit list for Bihar Police Constable is prepared based on PET performance — not written exam marks. The written exam only qualifies you for the PET; your PET performance ranks you for selection.

This means a candidate scoring 70% in the written exam but performing poorly in PET will rank below a candidate who scored 35% in written but excelled in PET.

Bihar Police Constable Written Exam Pattern 2026

The written exam is a 100-question, 100-mark, OMR-based objective test conducted in 2 hours:

Key exam rules:

• Negative marking: 0.25 marks deducted per wrong answer (one-quarter mark penalty).

• Duration: 2 hours (120 minutes).

• Mode: Objective MCQ — OMR sheet-based.

• Standard of questions: Class 10+2 (Intermediate) level — especially for Physics, Chemistry, and Mathematics.

• Minimum qualifying marks: 30% (30/100) — candidates scoring below 30% are eliminated and not called for PET.

• Medium: Hindi and English (bilingual paper).

Note on negative marking: Some sources indicate 0.25 negative marking while the CSBC official notification should be the final authority. Verify from csbc.bihar.gov.in at the time of your specific recruitment cycle.
