BPSC TRE 4.0 Apply Online 2026 (Class 1-5): Last Date 26 October, Eligibility, Fee & Steps

BPSC TRE 4.0 Apply Online 2026: Quick Answer

If you want to apply for BPSC TRE 4.0 (Class 1-5) online, the application window opened on 25 September 2026 and closes on 26 October 2026, with the fee payment deadline falling a day earlier on 25 October 2026. This is per BPSC's Advertisement No. 15/2026 for School Teacher recruitment under the Education Department, Government of Bihar. The preliminary (PT) exam date has not been announced yet — BPSC's own exam calendar states it "shall be published after completion of the advertisement period" — so the smartest use of the next few days is to finish your form carefully and start revising.

BPSC TRE 4.0 Key Dates (Advertisement No. 15/2026)

These dates are as per the official Important Notice on Advertisement 15/2026. Always cross-check the live date on BPSC's own exam calendar before you submit, since BPSC can issue a corrigendum at any time.

Who Can Apply for BPSC TRE 4.0 (Class 1-5)? Eligibility

BPSC TRE 4.0 covers School Teacher posts across Class 1-5, Class 6-8, Class 9-10 and Class 11-12, with a combined total of 32,388 posts per the official exam calendar (plus additional roster vacancies added for Class 9-10 and 11-12 through the 29 September corrigendum). The exact qualification required for each class level — subject-wise academic degree, teaching qualification such as D.El.Ed./B.Ed., and CTET/STET requirements — is laid out category-wise inside Advertisement No. 15/2026 itself. Because these conditions differ by subject and by reserved category, don't rely on summaries: open the official advertisement PDF and check the eligibility table for Class 1-5 before you fill the form. You can also see the post overview on SeatBeat's BPSC TRE 4.0 (Class 1-5) exam page.

One concrete update worth noting: as per the official notice dated 13 October 2026, candidates who passed the D.El.Ed. Training Session 2024-26 (Exam Year 2026) are permitted to upload the web copy of their marksheet while applying, instead of waiting for the original certificate.

Age Limit and Application Fee

BPSC specifies age limit and category-wise relaxation, along with the application fee for each category, inside Advertisement No. 15/2026. These figures were not independently confirmed from the officially extractable advertisement text at the time of writing, so rather than quote a number that could be wrong, we'd rather point you straight to the source: check the "Age Limit" and "Application Fee" clauses in the official advertisement PDF before you pay. What is confirmed officially is the timeline: fee payment must be completed by 25 October 2026, a day before the form submission deadline of 26 October 2026.

Documents Required to Apply for BPSC TRE 4.0 Online

Keep scanned copies of these ready before you start the form, in the format and size mentioned in the advertisement:

• Recent passport-size photograph and signature (as per prescribed specifications)
• Matriculation/10th certificate for date of birth proof
• Graduation and post-graduation mark sheets/certificates, as applicable to the subject and class level
• Teaching qualification certificate — D.El.Ed./B.Ed. (or web-copy marksheet, if you are a D.El.Ed. 2024-26 candidate per the 13 October 2026 notice)
• CTET/STET or equivalent teacher eligibility test scorecard, where required
• Category/caste certificate, EWS certificate, or disability certificate, if claiming reservation
• Valid photo ID for registration and application fee payment receipt

The exact, binding list and format is in the official advertisement — treat this as a preparation checklist, not a substitute for reading the PDF.

Common Mistakes to Avoid While Applying

• Confusing the fee deadline with the form deadline — fee payment closes on 25 October 2026, one day before the form submission closes on 26 October 2026. Paying late can lock you out of submitting.
• Waiting until the last day — heavy traffic near 26 October 2026 can slow down the portal; apply a few days early.
• Selecting the wrong class level or subject — Class 1-5, 6-8, 9-10 and 11-12 have separate eligibility, so double-check before you choose.
• Missing the corrigendum — the 29 September 2026 corrigendum added vacancies for Class 9-10 and 11-12; read every notice linked on the BPSC exam calendar, not just the main advertisement.
• Uploading documents in the wrong format or size, which can cause rejection at the scrutiny stage.
• Not saving the application printout/confirmation after submission.

What Happens After You Apply for BPSC TRE 4.0

Once you submit the form, BPSC will scrutinise applications and, in due course, release the admit card — this has not been announced yet as of 22 October 2026. The selection process has two stages: a Preliminary (PT) exam followed by Mains. Per BPSC's official exam calendar, the PT date itself will only be published after the application period closes, so there is no fixed exam date to plan around yet. Use this gap productively: read SeatBeat's BPSC TRE 4.0 2026 complete guide to posts, papers, pattern and preparation to understand the exam structure, and keep checking the official exam calendar for the PT date announcement.
