Bihar Teaching Exams: STET, TRE 4.0 & CTET Untangled

Bihar Teaching Exams 2026: STET, TRE 4.0 and the Eligibility Maze, Untangled

Bihar runs the largest school-teacher hiring machine in India, and in 2026 it has three moving parts that candidates keep confusing with each other: Bihar STET (the state eligibility test, run by the Bihar School Examination Board), BPSC TRE 4.0 (the actual recruitment examination for 32,388 school-teacher posts, run by the Bihar Public Service Commission), and CTET (the central eligibility test, run by CBSE, which Bihar's recruitments also accept at the relevant levels). STET and CTET qualify you. TRE employs you. Mixing up which is which is the single most common reason Bihar teaching aspirants waste a season.

TRE 4.0: the recruitment itself

BPSC's TRE 4.0 covers 32,388 Vidyalaya Adhyapak (school teacher) vacancies across Bihar's government schools, split by level in the widely reported roster: 3,847 posts for Classes 1–5, 8,563 for Classes 6–8, 3,877 for Classes 9–10, and 16,101 for Classes 11–12 — the senior secondary level is by far the biggest block. These are regular cadre posts under the Education Department, not contract/shikshak engagements, with district allotment through online preference, and starting basic pay by level reported at ₹25,000 (primary), ₹28,000 (middle), ₹31,000 (secondary) and ₹32,000 (senior secondary) per month plus state allowances.

Eligibility is level-specific and anchored in the NCTE framework plus a TET pass. Primary (1–5) runs on Senior Secondary with D.El.Ed. plus CTET/BTET Paper 1; middle (6–8) on graduation with teacher education plus TET Paper II; secondary (9–10) and senior secondary (11–12) on B.Ed. with post-graduation in the subject, gated by Bihar STET Paper I and Paper II respectively. Minimum age is 18 for primary/middle and 21 for secondary levels, with maximum age in the 37–42 band by category and Bihar's relaxation rules; reservation benefits are for Bihar domiciles. One provision deserves attention: candidates relying on STET 2026 could apply with a self-declaration (with their STET application number) that they would clear STET before the TRE preliminary — fail to clear it, and no admit card follows.

Selection is two written stages with no interview: a Preliminary examination (150 questions, 150 marks, with negative marking reported at 0.33 per wrong answer — and, unusually, negative marking touches unanswered questions unless the "none of the above" option E is marked), then a Main examination (150 questions: a 30-question qualifying language part requiring 30%, and a 120-question main part), with final merit from the Main examination alone. The BPSC exam calendar (dated 14 August 2026) listed the TRE 4.0 written-exam date as TBD, to be published after the advertisement period — as of this writing, candidates should treat any specific exam date circulating in groups as unconfirmed until BPSC publishes it.

A warning earned by this cycle's own history: TRE 4.0's application schedule has been revised more than once (an original September start, a postponement notice, and further revision reported in late September), so do not trust any closing date you read anywhere except the live advertisement on bpsc.bihar.gov.in on the day you apply. Applications go through the Commission's online portal with One Time Registration, at a flat application fee of ₹100 for all categories under Advt. 15/2026; BPSC accepts no hard copies.

Bihar STET 2026: the eligibility gate

STET is BSEB's eligibility test for secondary and senior secondary teaching — qualifying, not hiring. The 2026 registration portal has been live through the autumn (StudyDesk re-checked it on 9 October 2026 and found it still open with no closing date displayed even after a previously reported extension date had passed — an unusual situation that makes checking the portal itself, rather than summaries of it, essential). The portal shows a minimum age of 21 years as on 1 August 2026. If you are aiming at TRE secondary posts and do not yet hold an STET or equivalent qualification, STET 2026 is your binding constraint: everything else in your plan waits on it.

How to sequence your moves

1. Fix your level first— primary, middle, secondary, senior secondary — because every eligibility rule, TET paper and vacancy pool hangs off it.
2. Audit your TET positionCTET/BTET/STET passed, applied, or missing? If missing, STET 2026 registration (while open) is step one, before any TRE preparation.
3. Read the TRE 4.0 advertisement PDF on bpsc.bihar.gov.in end-to-end— subject combinations, domicile/reservation conditions, the self-declaration rule, attempt limits (a maximum number of attempts applies to this examination) — then apply through the OTR portal well before the closing date; first-week applicants dodge the portal congestion that hits every BPSC deadline.
4. Prepare to the exam's actual shapethe preliminary's language paper and negative-marking rules (including the option-E rule) reward candidates who have read the syllabus notice, not just solved question banks.

Bihar will hire teachers at scale again in this cycle — 32,388 posts is not a rumour, it is in BPSC's own calendar. But this is a process with shifting dates, split authorities and a genuine eligibility maze; the candidates who get appointed are the ones who tracked the official notices themselves, in order, instead of the summaries.
