Bihar Police Constable 2026: CSBC Calendar, Vacancies, Exam Pattern and PET Guide
Bihar Police Constable 2026: CSBC Calendar, Vacancies, Exam Pattern, PET and Selection
Bihar Police constable recruitment in 2026 is not one exam. It is eleven separate CSBC drives running on one published calendar, and the post you apply for decides your exam month, your physical test window and your result date.
This guide puts the whole 2026 picture in one place: who conducts it, how many posts are on the table, what the written paper actually looks like, what the PET demands of your body, and where the popular coaching pages get the details wrong. Every figure below is dated, and where sources disagree you will see both numbers instead of a confident guess.
Who actually conducts Bihar Police Constable recruitment
The recruiting body is the Central Selection Board of Constable (CSBC), Bihar, based in Patna. CSBC handles constable-rank hiring across the police department and its allied wings, including prohibition constable, jail warden, forest guard, driver constable and the technical constable posts.
Two other Bihar boards get confused with it constantly. BPSSC runs Sub-Inspector and Sergeant recruitment, which is a different advertisement with a different pattern; you can see how that cycle behaved in our write-up on the Bihar Police SI PET postponement and what it changed for candidates. BSSC is the Bihar Staff Selection Commission and handles clerical and inter-level posts, not police constables.
Getting this right matters practically. If you are hunting for a constable notification on the BSSC portal, you are on the wrong site and you will miss the window.
Bihar Police Constable 2026 at a glance
One honest caveat before you go further. The 32,202 total comes from a detailed post-wise table, while several aggregator headlines carry 31,603 for the same February calendar. Neither number is confirmed against a CSBC PDF in this write-up, so treat the total as approximate and the post-wise rows below as the more reliable part.
The CSBC 2026 exam calendar, post by post
This is the single most useful table for planning your year. It tells you which drives have already gone past their written stage and which ones still have a paper ahead of them.
Read that table with today's date in hand. If you are sitting on 30 August 2026, the Forest Guard, Forester and Prison Driver written exams in September 2026 are the nearest papers, and the June 2026 group has already moved into its physical stage. The main constable drive of 19,838 posts is at the result end of its cycle, not the application end.
Calendar dates from any board are indicative. CSBC has revised its own schedule before, so treat a month here as a planning anchor and the admit card as the only binding document.
Eligibility: age, qualification and who gets relaxation
Educational qualification
For the general constable post you need a Class 12 or Intermediate pass from a recognised board. Technical constable, radio operator and driver constable posts carry their own extra requirements such as a diploma or a valid heavy vehicle licence, and those are spelled out only in the individual advertisement for that post.
Age limits
The relaxations are the standard Bihar pattern: two years for BC and EBC men, three for BC and EBC women, five for SC and ST candidates of both genders, and five for serving Bihar Home Guards. The cut-off date for calculating age is fixed inside each advertisement, so check it there rather than assuming 1 January.
Domicile is worth a line. Category-based reservation and relaxation in Bihar recruitment generally apply to candidates domiciled in Bihar, and candidates from other states are usually considered in the unreserved pool. That rule shows up the same way in other state hiring, including the posts covered in our BSSC Inter Level 2026 vacancy, eligibility and syllabus breakdown.
Written exam pattern
The choice in Part 2 is the single most underrated feature of this paper. You pick two subjects out of eight, which means an arts student and a science student can both build a comfortable fifty marks without touching each other's territory.
Pick on the basis of scoring reliability, not affection. Polity and Geography reward a fixed syllabus and short revision cycles. Mathematics rewards speed but punishes a bad day. History is wide but predictable. Choose the pair you can revise fully in a weekend by December, not the pair that sounds impressive.
Syllabus break-up you can actually revise
Part 1: Hindi, English, Current Affairs and General Awareness
- Hindi: grammar basics, sandhi, samas, upsarg and pratyay, muhavare, paryayvachi and vilom, error spotting, short comprehension.
- English: parts of speech, tense, articles, prepositions, spotting errors, fill in the blanks, one word substitution, a short passage.
- Current Affairs: the last eight to twelve months, with Bihar-specific news carrying real weight in this paper.
- General Awareness: Indian history landmarks, geography of India and Bihar, Constitution basics, economy terms, general science, sports and awards.
Part 2: your two chosen subjects
- Mathematics: number system, percentage, ratio, average, profit and loss, simple and compound interest, time and work, time and distance, mensuration, basic algebra.
- Physics: motion, force, work and energy, light, sound, electricity, magnetism, units and measurement.
- Chemistry: matter, atomic structure, periodic table, acids bases and salts, metals and non-metals, carbon compounds, everyday chemistry.
- Biology: cell, tissues, human body systems, nutrition, diseases, plant physiology, environment.
- History: ancient, medieval and modern India, the freedom movement, and Bihar's role in it.
- Geography: physical geography, Indian rivers and soils, climate, Bihar's districts and rivers, world geography basics.
- Polity: Constitution, fundamental rights and duties, Parliament, judiciary, panchayati raj, state government structure.
- Economics: basic concepts, budget and taxation, banking, poverty and unemployment, Bihar's economy.
The academic level sits around Class 10 and 12 NCERT. You do not need degree-level depth in any of these, and a candidate who has genuinely finished the NCERT chapters for two chosen subjects is already ahead of most of the hall.
Application fee
The fee reported for the 2026 constable application is ₹100 for all categories. This is single-source in the material checked for this guide, and CSBC has used a two-tier fee structure in earlier cycles with a lower amount for SC and ST candidates of Bihar.
Do not budget on the basis of this line alone. Open the advertisement PDF on csbc.bihar.gov.in, read the fee clause, and pay only through the official payment gateway inside the application portal.
Selection process: written is a gate, PET is the scoreboard
The stages run in a fixed order and each one filters the pool for the next.
- Written examination: 100 marks, qualifying at 30 per cent.
- Physical Standard Test (PST): height, chest and weight measurement, purely pass or fail.
- Physical Efficiency Test (PET): running, high jump and shot put, scored out of 100.
- Document verification and medical: final appointment list.
Physical Standard Test (PST)
Physical Efficiency Test (PET), 100 marks
Read the running slabs carefully because this is where most candidates lose the post. Full 50 marks go to the fastest band, and the marks slide down towards 20 as your time creeps towards the outer limit. Crossing the limit is not a low score, it is elimination.
The sources checked for this guide describe the written paper as a qualifying screen and PET as the scored stage feeding the merit list, but no page reached this run carried the exact merit formula. Confirm the weightage clause in the advertisement before you decide how much time to give the written paper.
What most Bihar Police guides get wrong
Four errors show up again and again on aggregator pages, and each one can cost you a cycle.
- They call the board BSSC. Constable hiring is CSBC. BSSC is a different commission with different exams, and BPSSC is the SI board. Three acronyms, three portals.
- They print one exam date for all eleven drives. The 2026 calendar runs written papers in three separate clusters, from a completed September 2025 paper through June 2026 to September 2026. Your post decides your date.
- They treat the written score as your rank. It is a 30 per cent gate. Candidates who scored 70 in the written and 40 in the PET routinely lose to candidates who scored 45 and 85.
- They copy last cycle's fee and age cut-off. Fee figures and age reference dates change between advertisements, and every year a batch of applications is rejected for an age miscalculation that was correct two cycles ago.
There is a fifth, quieter mistake: preparing Part 2 for all eight subjects because a website listed all eight. You answer two. Reading all eight is not thoroughness, it is a way to be shallow in every one of them.
A prep plan that fits a real timeline
Assume you are targeting a written paper roughly twelve weeks out, which fits the September 2026 forest guard cluster or an early-2027 advertisement. Physical training runs in parallel from day one, not after the result.
Weeks 1 to 4: build the base
- Finish NCERT Class 9 and 10 for both chosen subjects. One chapter a day, notes in your own handwriting.
- Hindi grammar for 30 minutes daily, focused on sandhi, samas and muhavare.
- Start current affairs from month one of your window, not from today backwards.
- Running from week 1. Three sessions a week, building from 2 km slow to 3 km comfortable.
Weeks 5 to 8: convert reading into marks
- Two sectional tests a week per chosen subject. Log every wrong answer with a one-line reason.
- Bihar-specific GK block: districts, rivers, schemes, recent state news.
- Full English grammar revision, 45 minutes daily.
- Timed running: 1.6 km attempts once a week, plus high jump and shot put practice twice a week.
Weeks 9 to 12: exam-shape practice
- Two full 100-question mocks a week, in 2 hours, on paper with an OMR sheet.
- Rebuild your error log into a single revision sheet and read it every third day.
- Current affairs revision only from your own notes, no new sources.
- Peak physical block: two timed 1.6 km runs a week, then taper in the final ten days.
Keep one backup application open in the same window. Candidates who put every hope on a single constable advertisement lose a year when a date shifts, and a parallel clerical attempt costs you very little extra preparation. Our guide to the BSSC Inter Level 2026 syllabus and vacancies covers the closest overlapping option, and you can track other Bihar cycles on the ExamAtlas Bihar recruitment hub.
Practise on the paper, not around it
The Bihar Police constable paper rewards a very specific skill: answering 100 mixed questions in 120 minutes without losing five minutes to one stubborn sum. That is a habit, and habits only form under a clock.
Use the ExamAtlas Bihar exam hub to find full-length mocks in the CSBC format, take them at the same hour as your real slot, and treat every attempt as data. Your accuracy in the last twenty questions is the number that tells you whether your stamina is real.
Frequently asked questions
Who conducts Bihar Police Constable recruitment in 2026?
The Central Selection Board of Constable (CSBC), Bihar, based in Patna, through its official site csbc.bihar.gov.in. BPSSC handles Sub-Inspector recruitment and BSSC handles inter-level clerical posts. All three are different boards with different portals.
How many vacancies are on the CSBC 2026 calendar?
The calendar released on 24 February 2026 covers eleven drives. The post-wise table totals 32,202 posts, while several trackers headline the same calendar as 31,603. The largest single drive is the general constable recruitment with 19,838 posts, though one news report gives 19,383 for the same drive.
What is the Bihar Police Constable written exam pattern?
One offline OMR paper of 100 questions and 100 marks in 2 hours. Fifty questions cover Hindi, English, current affairs and general awareness. The other fifty come from two subjects you select from Mathematics, Physics, Chemistry, Biology, History, Geography, Polity and Economics. The qualifying mark is 30 per cent.
Is there negative marking in the Bihar Police Constable exam?
None of the sources checked for this guide stated a negative marking rule for the 2026 cycle. Since a wrong answer costing you marks changes your entire guessing strategy, read the marking clause in the advertisement PDF before your paper rather than relying on any coaching page.
What is the running requirement in the Bihar Police PET?
Male candidates run 1.6 km within a maximum of 6 minutes, female candidates run 1 km within a maximum of 5 minutes. The event carries 50 of the 100 PET marks, with the score sliding down from full marks towards 20 as your time approaches the limit. Crossing the limit is a disqualification, not a low score.
What are the height and chest requirements?
Male candidates in the general and BC categories need 165 cm height and an 81 cm unexpanded chest expanding to 86 cm. EBC, SC, ST and Gorkha male candidates need 160 cm, with 79 cm expanding to 84 cm for SC and ST. Female candidates in all categories need 155 cm height and a minimum weight of 48 kg. Chest measurement does not apply to female candidates.
Can a candidate from outside Bihar apply?
Candidates from other states can generally apply but are considered against unreserved posts, since category reservation and age relaxation in Bihar recruitment are tied to Bihar domicile. The exact clause is written into each advertisement, so read it before paying the fee.
Which two subjects should I choose in Part 2?
Choose the pair you can revise completely in one weekend by the last month of preparation. Polity and Geography suit most candidates because the syllabus is finite and the questions are direct. Mathematics is a strong pick only if your accuracy under a clock is already above eighty per cent.
Final word
One point deserves more attention than it usually gets: the 2026 calendar changes what a serious candidate should be doing right now. With eleven drives spread from a completed 2025 paper to a February 2027 result, the winning move is to apply across more than one post in the constable family rather than waiting for the one advertisement you had in mind.
The physical standards are almost identical across prohibition constable, jail warden, forest guard and general constable. The written paper follows the same 100-mark shape. That means the preparation you build once can be spent three or four times inside a single calendar year, and the candidate who applies to four drives has four chances at the same body of work.
Verify every date in this guide against csbc.bihar.gov.in before you act on it. Calendars move, fees change, and the advertisement PDF is the only document that counts on exam day.
