Bihar Police Prohibition Constable Exam Pattern, Eligibility

100 objective questions, one mark each, 2 hours, OMR sheet, Class 10 level. Subjects are Hindi, English, Maths, Social Science, Science and general knowledge. Below 30 percent is a fail, and written marks only select candidates for the PET, at roughly five per post.

The PET is 100 marks: run 50, shot put 25, high jump 25. A man must run 1.6 km in six minutes and a woman 1 km in five, or the other events are not offered. Shot put and high jump make up the other 50 marks; the high jump minimum is 3 ft for women. Merit comes from PET marks alone.

• Age: minimum 18 on 1 August 2025. Maximum 25 unreserved, 27 for BC and EBC men, 28 for BC and EBC women, 30 for SC, ST and transgender candidates. For the prohibition constable post the upper limit is counted as on 1 August 2023.

• Chest (men): 81 cm unexpanded, 86 cm expanded; 79 and 84 cm for SC and ST. Women: at least 48 kg.

The ad says persons with disabilities are not reserved posts in this recruitment.

Written test, PET, document verification, then medical and character checks by the Excise Commissioner for the prohibition post. Jail Warder is filled through the Prison department's own appointing authority. A tie in merit goes to the older candidate.

Prohibition Constable and Jail Warder are at pay level 3 (₹21,700–69,100). Mobile Squad Constable is at level 2.

The application fee in Advt. 03/2025 was a flat ₹100 for every category, plus bank charges. Apply through the CSBC portal, and have the caste, non-creamy-layer or EWS certificate (financial year 2024-25 for EWS) ready on the last date.

Shifts ran 10 am to 12 noon and 3 pm to 5 pm, in 38 districts. The next notices will appear on the Prohibition Dept. page.

The e-admit card for the June 2026 exam was available from 1 June 2026 on the CSBC site by registration number or mobile and date of birth. A bogus social media claim that the 17 June papers were postponed was denied by CSBC on 16 June.

The written result is a PET shortlist of roll numbers, dated 18 August 2026, linked from the CSBC page. Final merit will come after the PET and document verification.

No cut-off marks beyond the 30 percent qualifying line have been published. The PET shortlist is by category-wise merit at five times the vacancies.

The PET decides rank, so start with running pace. Use the written paper period for Class 10 maths and science and basic current affairs.
