The Bihar Public Service Commission (BPSC) on Tuesday, 18 August 2026, officially announced the Teacher Recruitment Examination (TRE) 4.0, opening a major hiring drive for teachers across primary, middle, secondary, and higher secondary schools in Bihar. The BPSC examination calendar lists 46,595 vacancies for TRE-4, though the official notification references 32,388 posts — candidates are advised to confirm the final, category-wise and subject-wise vacancy count through the Commission's detailed recruitment advertisement once published.

Key Changes in TRE 4.0

The most significant structural shift in TRE 4.0 is the introduction of a two-stage selection process: a Preliminary Test (PT) followed by a Main Examination. Previous BPSC teacher recruitment cycles relied on a single written examination, making this a notable departure. The examination is expected to be conducted in offline, OMR-based mode, requiring candidates to prepare for both stages accordingly.

The BPSC examination calendar has scheduled the TRE-4 examination from 22 September to 27 September 2026. A detailed shift-wise and subject-wise schedule may be issued separately by the Commission.

Eligibility and Qualification Requirements

Eligibility criteria vary by teaching level. Candidates applying for primary teacher positions must hold CTET Paper-I or STET Paper-I along with the prescribed educational and professional qualifications. Those targeting middle, secondary, or higher secondary posts must satisfy the respective educational, professional, and Teacher Eligibility Test (TET) requirements for each level.

The general age limit is 18 to 42 years, with relaxations applicable for reserved categories as per government norms. Candidates are strongly advised to verify exact age criteria for their specific category and post in the detailed advertisement before applying.

Application Window and Process

The online application window opens on 1 September 2026 and closes on 30 September 2026. Applications must be submitted through the official BPSC portal. Candidates should carefully review the detailed notification for post-wise eligibility, application fees, age limits, and all other requirements before submitting their forms.

What This Means for Aspirants

Bihar's teacher recruitment process has historically drawn hundreds of thousands of applicants, given the scale of vacancies and the relative job security of government teaching posts. The shift to a two-stage examination — PT followed by Mains — aligns BPSC's teacher hiring more closely with the pattern used in other state-level competitive examinations, potentially raising the bar for selection. This is the fourth edition of the TRE since BPSC took over teacher recruitment in Bihar, and the introduction of a preliminary round signals a move toward more rigorous screening. Aspirants who have cleared CTET or STET should begin preparing for both stages without delay, as the examination window begins as early as 22 September 2026.
