Teacher Levels Under BPSC TRE 4.0 and Their Papers

BPSC TRE 4.0 recruits teachers for four school levels, and the subject papers differ by level and, from Class 9-10 onward, by subject post as well.

Class 1-5 (Primary Teacher)

This is the level covered by SeatBeat's dedicated BPSC TRE 4.0 (Class 1-5) exam page. Primary-level candidates mainly need strong General Studies preparation alongside the qualifying language paper. Practice with the BPSC TRE 4.0 (Class 1-5) General Studies Mock Test Series (69 full tests, 3,270 questions, available in Hindi and English for ₹99) to build speed and accuracy on this paper.

Class 6-8 (Middle School Teacher)

You can prepare with the BPSC TRE 4.0 (Class 6-8) Maths & Science Mock Test Series (60 tests, 2,322 questions, ₹99). Start with the free mock test to check the difficulty level first.

Class 9-10 (Secondary Teacher)

Class 11-12 (Senior Secondary Teacher)

This is the highest level under TRE 4.0 and, per the September 2026 corrigendum, also received additional vacancies. Subject papers at this level follow the concerned subject (such as Physics, Chemistry, Biology, Maths, Commerce or Arts streams) as listed in the official advertisement; check the notification for the exact post-wise subject breakup for this level.

BPSC TRE 4.0 Exam Pattern and Selection Process

Per BPSC's official exam calendar, the TRE 4.0 selection process has two phases: a Preliminary (PT) exam followed by a Mains exam. Both stages are expected to be objective (MCQ) papers, consistent with how BPSC has run earlier teacher recruitment cycles, but the Commission has not yet published the exact paper-wise marks, number of questions or duration for TRE 4.0 in an officially extractable form. The PT exam date itself has not been announced; BPSC's exam calendar states it will be published only after the application period closes. Do not rely on third-party marks/duration charts for this cycle — check the official BPSC exam calendar and the advertisement PDF for the confirmed pattern once it is released, and watch that page for the PT date announcement.

Eligibility at a Glance

Eligibility (educational qualification, Teacher Eligibility Test requirement, and age limit) is defined separately for each level — Classes 1-5, 6-8, 9-10 and 11-12 — inside Advertisement No. 15/2026. Since these conditions vary by post and category, confirm the exact qualification, TET and age criteria for your level from the official advertisement PDF rather than any secondary source.

How to Prepare for BPSC TRE 4.0

Once the PT date is announced, you will have limited time to revise, so it helps to start full-length practice now rather than after the admit card arrives. For each level:

• Class 1-5 aspirants can work through the General Studies Mock Test Series.
• Class 6-8 aspirants can use the Maths & Science Mock Test Series.
• Class 9-10 aspirants can pick the series matching their subject — Science, Mathematics or Social Science.

Every SeatBeat BPSC TRE 4.0 series comes with full-length mock tests, Hindi and English solutions, and a free first test, so you can judge the question style before buying. If you are relocating to Bihar for this exam or for other BPSC/UPSC preparation, the first-week setup guide for Patna is worth a read.
