Work Experience Weightage – For Instructor (Electrician/Wireman) Post Only
📌 Unique Benefit for Contract Instructors: Candidates who have previously worked on contract basis as Instructor (same post) under the Science, Technology & Technical Education Department in Government Engineering Colleges or Government Polytechnics will get additional weightage marks.
| Criteria | Weightage |
|---|---|
| Satisfactory service per year on contract as Instructor (same post) | 5 marks per year |
| Maximum weightage | 25 marks (5 years of service) |
| Partial year calculation | More than 6 months but less than 1 year is counted as 1 full year |
Important Conditions for Weightage:
- • Only candidates who qualify the CBT (score minimum qualifying marks) are eligible for weightage.
- • Weightage marks are added to the converted CBT score (CBT percentage × 0.75 = marks out of 75).
- • Candidates must claim work experience in the online application and upload the Salary Payment Certificate (Annexure-1 format) issued by the Principal of the respective Government Engineering College/Polytechnic.
- • Certificate must be issued on or before 15 April 2026.
- • This weightage is NOT applicable for the Electrician post under Public Health Engineering Department.
Conversion Formula for CBT Marks (Instructor Post)
Final marks for Instructor post = (CBT percentage × 0.75) + Work experience weightage (max 25 marks)
Example: If a candidate scores 60% in CBT = 60 × 0.75 = 45 marks. If they have 3 years contract service = 15 marks. Total = 60 marks out of 100.
Selection Process – BTSC Recruitment 2026
Stage 1 – Computer Based Test (CBT)
All candidates must appear for the CBT (100 MCQs, 100 marks, 2 hours, negative marking 0.25). Candidates must score minimum qualifying marks for their category.
Stage 2 – Work Experience Weightage (Instructor Post Only)
CBT-qualified candidates claiming contract experience will have weightage added as per Annexure-1 certificate.

Stage 4 – Department/Post Allocation as per Preference
During counseling, candidates must clearly indicate their department/post preference. No changes will be allowed after counseling.

Expert Tips for BTSC Instructor & Electrician Recruitment 2026
1. Understand the Difference Between the Two Posts
Many candidates confuse the two posts. Instructor post (Level-6, ₹35,400) requires ONLY ITI – no Matric needed. Electrician post (Level-2) requires Matric + ITI (regular). If you have both qualifications, you can apply for both posts with separate applications. Choose based on your eligibility and career goals.
2. Ensure ITI is Regular Course – Distance Learning NOT Eligible
The notification explicitly states that distance learning ITI will NOT be given preference. Only regular course ITI from NCVT/SCVT recognized institutes is acceptable. If your ITI certificate is from distance/correspondence mode, you are NOT eligible.
3. For BC/EBC Candidates – Get Non-Creamy Layer Certificate
BC and EBC candidates must produce a valid Non-Creamy Layer certificate. A simple caste certificate is NOT sufficient for reservation benefits. The certificate must be issued by competent authority in Bihar. Apply for it immediately if you don’t have it.
4. For Contract Instructors – Get Salary Payment Certificate in Annexure-1 Format
If you have previous contract experience as Instructor, you must get the Salary Payment Certificate in the prescribed Annexure-1 format from the Principal of the Government Engineering College/Polytechnic. Any other format will NOT be accepted for weightage. The certificate must be issued on or before 15 April 2026.
5. Prepare for Negative Marking – Accuracy Over Speed
With 0.25 marks deducted per wrong answer, guessing is risky. Attempt only those questions you are confident about. In technical subjects, focus on core concepts. In GK and Reasoning, avoid guesswork. A score of 60-70 correct answers with no wrong attempts is better than 80 correct and 20 wrong.
6. Upload Clear, Legible Documents
BTSC will reject applications with blurry, dark, or unreadable documents. Use a good quality scanner (not mobile camera if possible). Ensure all text is clearly visible. The document verification will only accept what you uploaded – no new documents will be accepted later.
7. Keep All Original Certificates Ready for Document Verification
Selected candidates must produce original certificates for verification. If you claim work experience weightage, bring the original Salary Payment Certificate. If you claim PwD reservation, bring the original disability certificate. No certificates will be accepted at verification stage that were not uploaded in the application.
