BTSC JE Eligibility Criteria 2025

Aspirants must meet the prescribed educational qualification and age limit as of the crucial date specified in the detailed notification.

1. Educational Qualification (Minimum)

The primary and minimum educational requirement for the BTSC JE post is a Three-Year Diploma in the relevant engineering discipline from a recognized institution/university.

• For JE (Civil): Diploma in Civil Engineering.

• For JE (Mechanical): Diploma in Mechanical Engineering.

• For JE (Electrical): Diploma in Electrical Engineering.

Note: Candidates possessing a higher qualification, such as a B.E./B.Tech. Degree in the relevant field, are also considered eligible to apply.

2. Age Limit (As of the specified date)

• Minimum Age: 18 years.

• Maximum Age (General Male): 37 years.

Age relaxation is provided to reserved categories as per the Bihar Government rules. This typically includes relaxation for OBC/EBC (up to 40 years) and SC/ST (up to 42 years). Female candidates from the unreserved category also receive relaxation.

BTSC JE Selection Process 2025

The selection for the Junior Engineer posts will primarily be based on a two-stage process: a Computer-Based Test (CBT) and the evaluation of relevant Work Experience, followed by Document Verification (DV).

The merit list will be prepared by combining the scores from the CBT and the marks awarded for work experience, where each year of relevant work experience grants a specific weightage up to a maximum of 25 marks.

BTSC JE Exam Pattern 2025 (CBT)

Understanding the CBT pattern is crucial as it holds a 75% weightage in the final selection. The exam will be a single-paper test comprising technical and non-technical sections.

Key Details of the CBT:

• Exam Mode: Online (Computer-Based Test).

• Total Duration: 2 Hours (120 Minutes).

• Question Type: Multiple Choice Questions (MCQ).

• Marking: +1 mark for every correct answer.

• Negative Marking: 0.25 marks will be deducted for every incorrect answer (a crucial factor to keep in mind).

• Language: Bilingual (Hindi and English).
