BPSC TRE Notification 2026 at a Glance

Here's a quick overview of the current recruitment. Each row is explained in more detail further down.

You'll apply on the BPSC online portal (bpsconline.bihar.gov.in), where you first complete your One Time Registration.

What Changed: BPSC TRE Vacancy Raised from 32,388 to 33,320

This is the update that brought TRE 4.0 back into the headlines. BPSC added 932 posts to the recruitment through a revised vacancy notice under Advertisement No. 15/2026. All the new posts are at the secondary and higher secondary levels.

Reports say the extra posts came from a revised supplementary requisition received through the General Administration Department. One report dates the corrigendum to 29 September 2026. National news outlets carried the increase in early October 2026.

Where the 932 New Posts Went

Reading the table: most of the new posts are in languages, the arts and special education. If you studied Maithili, Bhojpuri, Music, Dance or one of the classical languages, check the revised subject-wise list carefully. You may have more seats to compete for than you expected.

Level-wise Vacancies After the Revision

Coaching and job portals report the revised level-wise split below. The four figures add up to exactly 33,320, but please confirm them against the official revised vacancy notice before you rely on them.

Higher secondary teaching (Classes 11–12) has by far the most posts. BPSC has also published district-wise lists for each class level and a separate district-wise list for transgender candidates, so look up your preferred district too.

BPSC TRE Important Dates You Must Not Miss

These are the dates that matter right now. The application window is already open, so the deadlines are close.

A Note on Conflicting Dates

You may see different dates on different websites, so here is why.

• Notification date: Some pages give 18 August 2026 as the notification date. That was the date of Advertisement No. 14/2026, which BPSC has since cancelled. The current notification is Advertisement No. 15/2026, dated 22 September 2026. Other pages give different dates again, so go by the advertisement number.
• Fee deadline: Most sources list 25 October 2026 as the last date for fee payment, but a few list 26 October 2026. Our advice: pay the fee by 25 October, one day before the application deadline, so you're safe whichever date is right.
• Old dates: The earlier advertisement gave an application window of 1 to 30 September 2026. Those dates no longer apply. Ignore any page that still shows them.

BPSC TRE Application Fee

The good news is that the fee is low.

A few points to keep in mind:

• Some sources say the ₹100 fee applies to each class level you apply for. If you're applying for more than one level, check the official notification for the exact total.
• You pay online, and bank charges may be added.
• The fee is reported to be non-refundable, so make sure you're eligible before you pay.
• Entering your Aadhaar number saves you the extra ₹200 biometric fee.

How to Apply for BPSC TRE 4.0: Step by Step

The whole process is online. Set aside an unhurried hour and have your documents scanned and ready before you start.

1. Visit the official portal. Go to bpsc.bihar.gov.in and follow the link to the online application portal.
2. Complete your One Time Registration (OTR). You'll need a working mobile number and email ID.
3. Log in and choose TRE 4.0. Select the advertisement for Advertisement No. 15/2026.
4. Fill in your details. Enter your personal, educational and category information carefully.
5. Select your class level and subject. Read the revised vacancy list first, especially if your subject is one of those that gained posts.
6. Upload your documents. Reports say candidates can upload the web copy of their marksheet. If you're appearing in STET 2026, use the self-declaration form BPSC has provided.
7. Pay the fee. Pay ₹100 online (plus ₹200 if you're not using Aadhaar), preferably by 25 October 2026.
8. Review and submit. Check every entry, submit the form, and download or print the confirmation.

Tip: Don't wait until 26 October. Websites often slow down near the deadline, and a failed payment on the last day is a stress you can avoid.

What Changed from the Last Cycle

If you followed TRE 3.0 or the first version of the TRE 4.0 notice, here's what's different.

From Advertisement 14/2026 to 15/2026

• Advertisement No. 15/2026 cancels and replaces Advertisement No. 14/2026 of 18 August 2026. If you started an application under the old notice, you'll need to apply again under the new one.
• The application window moved to 25 September to 26 October 2026.
• Vacancies rose from 32,388 to 33,320 in the later revision.

Rule Changes Reported for TRE 4.0

Coaching sources that have studied the notification list these major changes:

• Negative marking of one-third of a mark for each wrong answer has been introduced.
• A STET 2026 self-declaration option has been added.
• The application fee has been reduced to ₹100.
• Applications now go through a new OTR and DigiLocker/profile-based system.

Negative marking is the change that will affect your strategy most. Guessing blindly now costs marks, so accuracy matters as much as speed.

Compared with TRE 3.0

TRE 3.0, held in 2024, recruited for 87,774 vacancies. TRE 4.0 is smaller at 33,320 posts, so expect tougher competition for each seat. That's all the more reason to start serious preparation now.

Eligibility in Brief

To apply, you need the right degree or diploma for your class level and subject, a qualifying teacher eligibility test (STET or CTET, depending on the level), and you must fall within the age limits. Reports say the revised notice also clarifies the pass marks for the teacher eligibility test.

For the full details, including age limits, relaxations and qualifications by subject, read our detailed guide: BPSC TRE 4.0 Eligibility 2026: Age, STET/CTET & Degree.

Selection Process and Exam Date

Sources describe the selection process differently, so here are both versions.

• Several coaching sources describe a single objective written exam followed by document verification, with no interview.
• Others say the process has a Preliminary Test and a Main Examination, in line with the BPSC exam calendar, followed by document verification.

The official notification is the final word on this, so check the selection scheme in the PDF itself. The exam had originally been scheduled for 22–27 September 2026 but was postponed. BPSC will announce the new exam date separately.

How to Use the Time Before the Exam

Once your form is in, put your energy into preparation. Here's a simple plan:

• Master the syllabus first. Build your basics from SCERT and NCERT textbooks, then add focused material. Our Books for competitive exams cover teaching-exam subjects and general studies.
• Practise under exam conditions. With negative marking in place, timed mock tests teach you when to attempt a question and when to skip it. Try our Online test series to track your progress.
• Stay current. The general studies section rewards regular reading. Spend 20 minutes a day on our Daily current affairs, with special attention to Bihar-related news.
• Revise weekly. Short, regular revision sessions work better than last-minute cramming.

Conclusion

To sum up the BPSC TRE notification and important dates: TRE 4.0 now offers 33,320 teaching posts under Advertisement No. 15/2026, after 932 posts were added for Classes 9–10 and 11–12. The application window closes on 26 October 2026. Pay your ₹100 fee by 25 October to be safe. The exam date will be announced later.

Don't let the deadline catch you out. Apply this week, check the revised subject-wise list for your subject, and start your preparation. You can do this, and every day of steady work now puts you closer to your own classroom. All the best!
