Bihar BTSC Laboratory Assistant Recruitment 2026 — 1091 Posts Prayogshala Sahayak | Advt. No. 02–13/2026 | btsc.bihar.gov.in | Notif. Date: 03.04.2026
Bihar Technical Service Commission (BTSC) has released a recruitment notification for 1091 Laboratory Assistant (Prayogshala Sahayak) posts under the Science, Technology & Technical Education Department, Government of Bihar. This is one of the largest technical recruitment drives in Bihar in 2026, covering 12 engineering and science disciplines through Advertisement Numbers 02/2026 to 13/2026. Candidates holding a relevant Diploma, B.E., B.Tech, or Science degree can apply online at btsc.bihar.gov.in from 6 April to 6 May 2026. Selection is through a Computer Based Test followed by Document Verification. The pay scale is Pay Level-4 (₹25,500–₹81,100) as per the 7th Pay Commission.
The Bihar Technical Service Commission (BTSC), headquartered at 19 Harding Road, Patna, is the state-level body responsible for technical recruitment across Bihar's government departments. This 2026 notification is significant because it fills Laboratory Assistant (Prayogshala Sahayak) positions across government polytechnic institutes, engineering colleges, and technical education centres under Bihar's Science, Technology & Technical Education Department — institutions that form the backbone of skill development and technical training in the state.
What makes this recruitment particularly noteworthy is its structure: rather than a single advertisement, BTSC has issued 12 separate advertisement numbers (02/2026 to 13/2026), one for each discipline. This means candidates apply under the specific advertisement number for their own discipline, and the merit list is prepared discipline-wise. A candidate with qualifications in multiple disciplines may apply for each relevant discipline separately. The total of 1091 posts spans disciplines ranging from high-demand Computer Science & IT (252 posts) to niche fields like Agriculture & Machinery (1 post) and Automobile/Mechanical Diesel (4 posts).

The 1091 vacancies are spread across 12 distinct engineering and science disciplines, each governed by a separate advertisement number. Computer Science & IT dominates with 252 posts — nearly 23% of total vacancies — reflecting Bihar's push to strengthen digital infrastructure in technical education. Electrical Engineering, Civil Engineering/Rural Engineering, and Mechanical Engineering each carry 166 posts, making them the next most sought-after options. Science (general) has 164 posts. Niche fields like Agriculture & Machinery (1 post), Automobile/Mechanical Diesel (4 posts), Chemical Engineering (2 posts), Ceramics (2 posts), and Printing Engineering (2 posts) are available for highly specialised candidates but will be extremely competitive given their small numbers.

The educational qualification for BTSC Lab Assistant varies by discipline. For most engineering posts, candidates need either a Diploma or a Degree (B.E./B.Tech) in the relevant engineering field. For the Science post (Advt. 12/2026), the minimum qualification is an Intermediate (10+2) with Science from a recognised board — making this the most accessible post in terms of entry-level qualification. Candidates with higher qualifications (B.Sc., M.Sc., or B.Tech) applying for science posts will earn additional marks in the merit list through the work experience/higher qualification component.
Out-of-state candidates are also eligible to apply, but they will not be entitled to any reservation benefits that are exclusively available to Bihar domicile holders. They must apply under the Unreserved category and compete accordingly. There is no domicile restriction mentioned as a blanket disqualifier — Bihar is notably more open to non-domicile applicants than states like MP or UP for its technical positions.
| Criterion | Requirement | Important Note |
|---|---|---|
| Nationality | Indian Citizen | As per constitutional provisions |
| Education — Science Post (Advt. 12/2026) | Intermediate (10+2) with Science from a recognised Board/University | Lowest qualification requirement across all 12 disciplines — accessible to 12th pass Science students |

Laboratory Assistant posts in Bihar's technical education department fall under Pay Level-4 of the 7th Pay Commission with a pay range of ₹25,500 to ₹81,100. The entry pay at Level-4 starts at ₹25,500 per month as basic pay. When DA (Dearness Allowance), HRA (House Rent Allowance), and other state government allowances are added, the gross in-hand salary for a newly joining Laboratory Assistant typically works out to ₹35,000–₹45,000 per month depending on the city of posting and applicable allowances at the time of joining. The DA component changes quarterly based on AICPI index.
Beyond the immediate salary, government laboratory positions in Bihar's technical institutions offer structured career progression within the state technical education cadre, job security as a permanent state government employee, and the professional satisfaction of contributing to hands-on technical education for thousands of students every year. Selected candidates are typically posted across government polytechnics and engineering colleges spread throughout Bihar's 38 districts.

The BTSC Lab Assistant selection does not involve any interview — the entire process rests on the CBT performance and document-verified work experience/higher qualification marks. The Computer Based Test carries 75% of the final merit, making it by far the most decisive stage. The remaining 25% comes from marks awarded for work experience in a related field and/or possession of higher educational qualifications beyond the minimum requirement. This system rewards both exam performance and real-world experience equally.
The CBT consists of 100 objective-type (MCQ) questions covering two areas: technical questions from the candidate's discipline, and General Knowledge. The exact split between technical and GK questions will be clarified in the detailed notification. Crucially, there is a negative marking of 0.25 marks per wrong answer — meaning a wrong answer costs you one-quarter of a mark. Candidates should adopt a careful, selective approach rather than attempting all questions blindly.
| Stage | Details | Weightage |
|---|---|---|
| Computer Based Test (CBT) | 100 objective-type MCQs — Technical subject questions + General Knowledge. Negative marking: −0.25 per wrong answer. Online mode only. | 75% of final merit |
| Work Experience / Higher Qualification | Marks awarded for relevant work experience in the discipline AND/OR higher educational qualification beyond the minimum required (e.g., B.Tech for a diploma-minimum post, M.Tech/M.Sc. for degree-minimum post) | 25% of final merit |
| Document Verification (DV) | Shortlisted candidates called to verify originals of all submitted documents. Failure to produce valid originals = disqualification. No marks awarded at DV — it is purely qualifying. | Qualifying only |
| Final Merit List | Prepared discipline-wise and category-wise based on CBT + Experience/Qualification weightage | 100% |
- No interview: The selection process has no personal interview at any stage — CBT performance and documents are the only deciding factors
- Negative marking: −0.25 marks per incorrect answer in CBT. Unattempted questions carry no penalty — do not guess randomly
- Minimum qualifying marks: Category-wise minimum qualifying marks in CBT will be specified in the detailed notification as per BTSC rules
- Work experience bonus: Candidates with relevant industry or lab experience gain up to 25% additional merit advantage — even freshers can compete but may rank lower than experienced candidates with similar CBT scores
- Discipline-wise merit lists: Final merit lists are prepared separately for each of the 12 disciplines — no cross-discipline competition
- Normalisation: If the CBT is conducted in multiple shifts, score normalisation will be applied to ensure fairness across shifts
- Out-of-state candidates: Eligible to appear in CBT but reservation benefits applicable only to Bihar domicile holders
One of the most candidate-friendly aspects of BTSC Lab Assistant Recruitment 2026 is the flat fee of ₹100 for all categories — including General, OBC, EBC, SC, ST, and EWS. There is no fee variation by category, making this genuinely accessible to every eligible applicant. Payment must be completed online through the BTSC portal using Credit Card, Debit Card, or Net Banking. Cash payments or bank challan modes are not accepted.
| Category | Application Fee | Mode of Payment |

📝 Stage 1 — Computer Based Test (CBT): 100 objective-type MCQs covering the relevant technical discipline and General Knowledge. Negative marking: −0.25 marks per wrong answer. CBT carries 75% weightage in the final merit.
🏅 Work Experience / Higher Qualification: Marks are awarded for relevant work experience and/or higher educational qualifications — carries 25% weightage in the final merit.
📋 Stage 2 — Document Verification (DV): Shortlisted candidates called to verify original documents. Qualifying in nature — no additional marks awarded. Failure to produce valid originals = disqualification.
Final merit list is prepared discipline-wise and category-wise based on CBT + experience/qualification combined score.
Entry pay starts at ₹25,500 per month as basic. With DA (Dearness Allowance), HRA (House Rent Allowance), and other state government allowances, the approximate gross monthly salary for a newly joining Lab Assistant is typically in the range of ₹35,000 to ₹45,000 per month, depending on the posting location and current DA rates.
This is a regular/permanent government appointment — not contractual — with full pension (NPS), medical benefits, and other state government perks.
However, there is an important merit consideration: the final selection gives 25% weightage to work experience and/or higher qualifications. This means:
✓ A fresher with no experience starts the merit with only CBT marks (75% weightage)
✓ A candidate with relevant work experience AND higher qualification gets full 100% merit score potential
Practically, experienced candidates have a significant merit advantage over freshers with identical CBT scores. Freshers should aim to score very highly in the CBT to compensate. There is no interview, so CBT performance is the key differentiator for freshers.
However, important restrictions apply:
❌ Reservation benefits (OBC/EBC/SC/ST category seats) are available only to Bihar domicile holders
❌ Out-of-state candidates must compete in the Unreserved (UR) pool
❌ No Bihar-specific age relaxation or fee concessions for non-Bihar residents
✓ Out-of-state candidates ARE eligible for the CBT and can be selected if they rank within the UR cut-off
✓ This makes BTSC Lab Assistant more open than many state-level recruitments which restrict to domicile holders only
Since each discipline has its own advertisement number (02/2026 to 13/2026), candidates need to:
✓ Submit a separate application for each discipline
✓ Pay a separate ₹100 fee per application
✓ Appear in the CBT separately for each discipline (the CBT will likely be conducted on different dates or with different question sets per discipline)
For example, a B.Tech (CSE) graduate with a minor in Electronics can apply for both Advt. 09/2026 (CSE/IT) and Advt. 05/2026 (Electronics), paying ₹100 for each and appearing in both CBTs. Selection in one discipline does not affect candidature in another.
