BPSC TRE 4.0 Eligibility 2026: Which Paper Do You Actually Need - CTET, BTET or STET?
BPSC TRE 4.0 Eligibility 2026: Which Paper Do You Actually Need - CTET, BTET or STET?
BPSC released the TRE 4.0 notification (Advt. No. 14/2026) on 18 August 2026 with 32,388 teacher vacancies, and the online form opens on 1 September 2026. Within a week, the same three questions flooded every Telegram group: "Can I apply for 6-8 with only CTET Paper-I?", "Is STET compulsory for 9-10?", "Does B.Ed. work for primary?"
The answers decide whether your form survives document verification or gets rejected after you spent months preparing. This guide breaks down the eligibility for each of the four levels, sorts out the CTET vs BTET vs STET confusion, and flags the traps that got forms cancelled in TRE 2.0 and 3.0. Everything below is compiled from the notification coverage; before paying the fee, verify each condition against the official Advt. 14/2026 PDF on bpsc.bihar.gov.in.
BPSC TRE 4.0 at a Glance
Important Dates
One month of window sounds like a lot. It is not. In TRE 3.0 the BPSC server crawled in the final three days, and candidates from Saharsa and Kishanganj reported OTP delays at midnight. Apply in the first two weeks.
Level-Wise Vacancy Breakdown
Read that table twice. Nearly half the posts (16,101) are for classes 11-12, which means STET Paper-II holders with a post-graduate degree are sitting on the best vacancy-to-competition ratio TRE has ever offered. Primary, with only 3,847 seats, will be the bloodbath this time.
Eligibility, Level by Level
Primary Teacher (Classes 1-5)
- Education: Senior Secondary (12th) with at least 50% marks plus a 2-year D.El.Ed. Graduation-based routes listed in the official PDF also apply.
- Teacher eligibility test: CTET Paper-I or BTET Paper-I qualified.
- Minimum age: 18 years.
The classic trap: CTET Paper-II does not make you eligible for classes 1-5. Paper-I is for 1-5, Paper-II is for 6-8, and BPSC treats them as separate qualifications, not a hierarchy.
Middle School Teacher (Classes 6-8)
- Education: Graduation plus D.El.Ed. or B.Ed.
- Teacher eligibility test: CTET Paper-II or BTET Paper-II qualified.
- Minimum age: 21 years.
Note the difference from 9-10: for classes 6-8 the accepted tests are CTET/BTET, not Bihar STET. If you cleared STET Paper-I but never wrote CTET or BTET Paper-II, the 6-8 door stays closed.
Secondary Teacher (Classes 9-10)
- Education: Graduation or Post-graduation in the concerned subject with at least 50% marks, plus B.Ed.
- Teacher eligibility test: Bihar STET Paper-I qualified (in the relevant subject).
- Minimum age: 21 years.
Senior Secondary Teacher (Classes 11-12)
- Education: Post-graduation in the relevant subject with at least 50% marks, plus B.Ed.
- Teacher eligibility test: Bihar STET Paper-II qualified (in the relevant subject).
- Minimum age: 21 years.
Subject matching matters here. STET Paper-II in Physics does not qualify you for the Mathematics post even if your M.Sc. is in Maths. BPSC verifies the STET subject against the post subject, and mismatches were a common rejection reason in TRE 3.0 counselling.
CTET vs BTET vs STET: Which Test Opens Which Door
A follow-up question we get daily: "STET ka form abhi bhara hai, result nahi aaya - can I apply?" The aggregator articles are silent on whether STET-appearing candidates get provisional entry this cycle. Do not assume. Check the exact wording in the official Advt. 14/2026 PDF, because TRE cycles have flip-flopped on this rule before.
Age Limit (as on 1 August 2026)
Minimum age is 18 for primary and 21 for the other three levels. Age is counted as on 1 August 2026, so calculate from your matric certificate date, not from memory.
Application Fee
Pay by 29 September even if you submit the form later; an unpaid form is an unsubmitted form in BPSC's system.
How to Apply
- Go to bpsc.bihar.gov.in and complete the one-time registration (OTR) if you have not already.
- From 1 September, open the TRE 4.0 (Advt. 14/2026) apply link and log in.
- Fill personal details exactly as they appear on your matric certificate.
- Select your level and subject carefully. TRE allows multiple levels if you are eligible for each, but every level needs its own eligibility proof.
- Upload photo, signature, and documents in the prescribed size.
- Pay the fee, submit, and download the confirmation PDF.
Documents to Keep Ready Before 1 September
- Matric certificate (for date of birth) and marksheets of 12th, graduation, and post-graduation as per your level.
- D.El.Ed. or B.Ed. degree with final marksheet, not just the provisional slip.
- CTET, BTET, or STET certificate with roll number and qualifying year visible.
- Caste certificate, domicile certificate, and EWS certificate where applicable, all in the current format issued from Bihar.
- Scanned photo and signature in the size BPSC specifies, plus a working mobile number that stays with you through counselling.
Scan everything this week. Half the last-minute panic in TRE 3.0 was people hunting for a working scanner in their block market on 29 September.
Mistakes That Got Forms Rejected in Earlier TRE Cycles
- Applying for 6-8 with CTET Paper-I only. Paper-I covers 1-5, nothing above it.
- STET subject not matching the post subject for 9-10 and 11-12.
- Percentage below 50% in the qualifying degree without checking the category-wise relaxation table in the PDF.
- Uploading a B.Ed. provisional certificate where the final one was required.
- Waiting for the "last date extension" rumour. TRE 3.0 got no extension.
My honest advice: spend 30 minutes with the official PDF and a highlighter before touching the form. One eligibility clause read carelessly costs a whole cycle, and the next TRE may be a year away.
Eligible? Here Is Your Next 5 Weeks
The exam pattern this cycle has its own twist. BPSC has signalled a two-phase Prelims plus Mains structure for TRE 4.0, which changes how you should prepare from day one; we covered the announced structure in our TRE 4.0 Prelims + Mains pattern explainer. Negative marking figures reported by coaching sites differ from each other, so treat the official PDF as the last word there too.
Start with the level-wise syllabus (our TRE 4.0 syllabus breakdown maps it topic by topic), then move to daily practice. ExamAtlas has free TRE-focused mock tests with AI analytics that show your topic-wise accuracy, which matters more than total attempts when the paper has 80 marks riding on your subject section. The mock test section also carries Bihar GK sets that TRE papers love.
Frequently Asked Questions
Is STET compulsory for all TRE 4.0 posts?
No. STET (Paper-I or II) is required only for classes 9-10 and 11-12. For classes 1-5 you need CTET Paper-I or BTET Paper-I, and for 6-8 you need CTET Paper-II or BTET Paper-II.
Can I apply for more than one level in TRE 4.0?
Yes, if you hold the separate eligibility for each level, you can apply for multiple levels. Each level checks its own qualification, TET/STET paper, and subject match.
What is the last date to apply for BPSC TRE 4.0?
The online form runs from 1 September to 30 September 2026, with fee payment closing on 29 September 2026.
I have B.Ed. but no D.El.Ed. Can I apply for primary (1-5)?
The reported qualification for 1-5 centres on D.El.Ed. with 12th (50%). B.Ed.-route eligibility for primary has shifted across TRE cycles after the NCTE and court rulings, so confirm the exact clause in the official Advt. 14/2026 PDF before applying.
What is the age limit for TRE 4.0?
Minimum 18 years for primary and 21 for other levels; maximum 37 (UR male), 40 (UR female, BC, EBC), and 42 (SC/ST), all counted as on 1 August 2026.
How many vacancies are there for classes 11-12?
16,101 out of 32,388 total posts, the single largest share in TRE 4.0. STET Paper-II qualified post-graduates should not miss this cycle.
Final Word
Eligibility is not the boring part of TRE 4.0; it is the part that eliminates more candidates than the cut-off does. Match your TET/STET paper to the right level, verify your subject mapping, and file the form early in September. Then forget the form and give the remaining weeks to the syllabus, because with 32,388 posts on the table, this is the cycle where prepared candidates from every district of Bihar get their shot.
