If you've been waiting for a government teaching job in Bihar, you've probably heard the name TRE 4.0 a dozen times already. Bihar has been running these Teacher Recruitment Exams almost like clockwork since 2023, filling lakhs of school teacher posts across the state. TRE 4.0 is the next one, and this time the government has promised something students have wanted for years: an exam every year, not once in three.
This post lays out everything on BPSC TRE 4.0 as things stand in August 2026 — vacancy numbers, dates, eligibility, exam pattern, syllabus, salary and how to prepare. Numbers have moved around across different announcements, so we'll flag where things are still tentative.
Quick Answer
BPSC TRE 4.0 has been announced but the final detailed notification (advertisement PDF) from BPSC is still awaited as of early August 2026. The Bihar government has confirmed close to 32,388 to 46,595 teacher vacancies (the number has varied across official statements) for classes 1 to 12, with the written exam tentatively set for 22 to 27 September 2026. Online applications are expected to open around March-April 2026 through the BPSC OTR portal, and candidates with a valid TET/CTET/STET certificate can apply. Keep checking bpsc.bih.nic.in for the confirmed advertisement.
Latest notification and important dates
The Bihar Education Minister announced vacancy numbers and a tentative exam window in February 2026, but the detailed BPSC advertisement was still pending as of the last update. Here's the timeline as it stands, with tentative items marked clearly.
| Event | Date / Status |
|---|---|
| Vacancy and exam date announcement | 17 February 2026 (announced by state government) |
| Detailed BPSC notification (advertisement) | Awaited — expected soon |
| Online application (OTR + form) | Tentative, around March 2026 |
| Last date to apply | Tentative, around April 2026 |
| Written exam | Tentative, 22 to 27 September 2026 |
| Admit card | Expected 1 to 2 weeks before exam |
| Result | Tentative, November 2026 |
Since the official PDF hasn't dropped yet, treat these dates as a working estimate. Once BPSC releases the actual notification, dates could shift by a few weeks either way — this is normal for TRE cycles, since TRE 3.0 also saw its exam pushed back more than once. For a running update, check pareeksha.in's exam news section.
What the job actually is
A TRE-recruited teacher is a regular government school teacher posted under the Bihar Education Department. Depending on which post you clear, you'll teach all subjects to young children (Class 1-5), specialise in two or three subjects for middle school (Class 6-8), or teach one subject as a specialist at secondary or senior secondary level (Class 9-12).
Day to day, the job means classroom teaching, correcting notebooks, handling mid-day meal and attendance registers, and helping run school exams. Postings can land you anywhere in Bihar, often far from your home district, at least for the first few years. It's a stable, pensionable-track government job with a fixed pay scale, which is why lakhs of candidates apply for every TRE cycle.
Vacancy details / post breakdown
Different official statements have given different total numbers for TRE 4.0, ranging from about 32,388 to over 46,000 posts. The most commonly repeated breakdown by class level looks like this (treat exact figures as provisional until BPSC confirms them):
| Level | Posts | Approx. Vacancies |
|---|---|---|
| Primary Teacher | Class 1-5 | around 3,800-8,000 |
| Middle School Teacher | Class 6-8 | around 8,500-10,000 |
| Secondary Teacher (TGT) | Class 9-10 | around 3,800-6,000 |
| Senior Secondary Teacher (PGT) | Class 11-12 | around 16,000-20,000 |
The senior secondary (11-12) segment has consistently had the largest chunk of vacancies across TRE cycles, mainly because Bihar keeps opening new +2 schools and needs subject specialists. Once the final advertisement is out, the subject-wise and district-wise split will be published as an annexure — don't lock in your prep around unofficial numbers.
Eligibility
You need to be a graduate with a teacher training qualification and a valid TET/STET score to apply for BPSC TRE 4.0. Requirements differ slightly by post.
Age limit (as of the cut-off date, typically 1 August of the exam year):
| Category | Minimum age | Maximum age |
|---|---|---|
| General (Male) | 18 (Class 1-8) / 21 (Class 9-12) | 37 years |
| General (Female) / BC / EBC | 18 (Class 1-8) / 21 (Class 9-12) | 40 years |
| SC / ST | 18 (Class 1-8) / 21 (Class 9-12) | 42 years |
| PwD (Divyang) | 18 (Class 1-8) / 21 (Class 9-12) | 47 years |
A key change from earlier TRE cycles: for Class 9-12 posts, the minimum age has been raised to 21, unlike the Class 1-8 posts where 18 is enough.
Education and TET requirements: Primary Teacher (1-5) needs graduation with D.El.Ed or B.Ed, plus CTET Paper 1 or Bihar TET. Middle School (6-8) needs a graduate/postgraduate degree with B.Ed or D.El.Ed, plus CTET Paper 2 or Bihar TET. Secondary/TGT (9-10) needs a relevant subject degree with B.Ed, plus Bihar STET Paper 1. Senior Secondary/PGT (11-12) needs a postgraduate degree in the subject with B.Ed, plus Bihar STET Paper 2.
Bihar domicile isn't compulsory to apply, but it matters for reservation and fee benefits — SC, ST, EBC, BC and EWS concessions apply only to Bihar domicile holders. Candidates from outside Bihar can apply under the general category. Women get 35% horizontal reservation within each category if they hold Bihar domicile.
Application process, fee and how to apply
You apply online through the BPSC OTR (One Time Registration) system on bpsc.bih.nic.in, and the fee is 750 rupees for general category and 200 rupees for SC/ST/PwD/Bihar-domicile women.
| Category | Fee |
|---|---|
| General / OBC / EWS (all India) | ₹750 |
| SC / ST / PwD | ₹200 |
| Female candidates with Bihar domicile | ₹200 |
Steps to apply: complete One Time Registration (OTR) on the BPSC website first, since it's a one-time candidate profile reused across all BPSC exams. Once the TRE 4.0 link is live, log in with your OTR credentials and fill in personal, educational and TET/STET details, choosing your preferred post and subject. Upload your photo, signature, marksheets, degree certificate, TET/STET certificate and category/domicile certificate if applicable. Pay the fee online, then review everything and submit. Download the confirmation page for your records.
Don't rush the OTR step — a mismatch in your name, DOB, or photo specs is one of the most common reasons applications get rejected later at document verification.
Exam pattern
BPSC TRE 4.0 is a single-stage written exam with objective questions and no interview. The pattern differs slightly by post level.
| Post | Duration | Questions/Marks | Sections |
|---|---|---|---|
| Primary Teacher (1-5) | around 2.5 hours | 150 questions, 150 marks | Language (qualifying) + General Studies, Maths, Reasoning |
| Middle/Secondary/Senior Secondary | around 2.5 hours | 150 questions, 150 marks | Language (qualifying, 30 marks) + Subject/General Studies (120 marks) |
The Language paper (Hindi/English/Urdu/Bangla) is qualifying in nature — you need to clear a minimum score, but marks from it don't count toward the final merit. The second part, covering General Studies for lower levels and the relevant subject for TGT/PGT posts, is what actually decides your rank. There's no negative marking in TRE exams, which is a relief compared to many other government papers — attempt every question you can.
Detailed syllabus
For Primary and Middle school posts (Class 1-8), the General Studies section covers General Science (Physics, Chemistry, Biology basics), Indian History with focus on the freedom struggle and Bihar history, Geography (Indian and Bihar-specific), Polity basics, current affairs, basic Maths (arithmetic, percentage, ratio, interest), Reasoning (analogy, series, coding-decoding, blood relations), and Bihar-specific GK covering culture, festivals and government schemes.
For Secondary and Senior Secondary posts (Class 9-12), the subject-specific section decides your rank. A Maths TGT/PGT paper covers algebra, geometry, trigonometry, calculus (PGT level) and statistics at graduation depth. Science teachers get questions from their specific stream at graduate level, mixed with some pedagogy questions.
Practising subject questions daily matters more here than general awareness cramming. Use topic-wise practice sets to test yourself section by section, and don't skip free mock tests that simulate the real 150-question format under time pressure.
Salary, pay scale and career growth
A BPSC TRE teacher earns a starting basic pay depending on post level, with total in-hand salary ranging roughly from 32,000 to 60,000 rupees a month after allowances. Bihar has moved teachers hired through TRE cycles onto a pay-scale structure similar to other state government employees, replacing the older honorarium system used for earlier "Niyojit" teachers.
Rough in-hand numbers reported across TRE cycles: Primary Teacher around ₹32,000-40,000, Middle School Teacher around ₹35,000-45,000, Secondary (TGT) around ₹42,000-50,000, and Senior Secondary (PGT) around ₹50,000-60,000. On top of basic pay, you get Dearness Allowance, House Rent Allowance and Travel Allowance, along with pension benefits under the New Pension Scheme. Career growth happens through seniority-based promotions to headmaster and higher administrative posts over the years, plus periodic pay revisions.
Previous year cut-off (TRE 3.0, for reference)
Since TRE 4.0's own cut-off won't exist until after the exam, here's what TRE 3.0 (2024) looked like for Primary Teacher — General subject, out of 150 marks, to give you a sense of the competition level.
| Category | Male | Female |
|---|---|---|
| Unreserved (UR) | 67 | 57 |
| EWS | 56 | 48 |
| EBC | 55 | 44 |
| BC | 60 | 50 |
| SC | 47 | 39 |
| ST | 46 | 39 |
Cut-offs for TGT and PGT posts vary a lot by subject — Science or English see tougher competition, while niche subjects can have lower cut-offs. Don't fixate on one number; aim to comfortably clear the UR cut-off regardless of your category if you want a safety margin.
Best books and preparation strategy
Start with the basics and build up. If you have 5-6 months before the exam, here's a rough plan: spend the first two months on NCERT Class 6-10 for Science, History, Geography and Polity, along with Bihar GK, using the General Awareness guide. Month three is for Maths and Reasoning fundamentals with the Quantitative Aptitude guide and Reasoning guide — both scoring if you practice daily. TGT/PGT candidates should give month four almost entirely to their subject, revising graduation textbooks and weak topics. In month five, add daily current affairs from Pareeksha's current affairs section and start weekly full mocks. In the final month, only revise and take timed mocks — 2-3 a week from the free test series to build speed for the 150-question format.
For books, standard state PSC publications (Lucent's General Knowledge, NCERT sets, and any updated Bihar TRE-specific guide) cover most of what's asked. Don't buy five different guides — one solid book per subject, revised three or four times, beats five books read once.
Common mistakes / honest advice
A lot of candidates lose marks not because the paper is hard, but because of avoidable errors. Applying under the wrong post or subject due to TET/STET confusion is common — check your certificate validity before filling the form. Many candidates also barely scrape through the qualifying language paper, which is risky if that cut-off is strict. TGT/PGT aspirants often spend too much time on general awareness and too little on their actual subject, when the subject paper is what really decides the rank. And there's no real reason to wait for the "final" notification before starting prep — the syllabus and pattern rarely change much between TRE cycles.
