What is the Eligibility for BTSC Scientific Assistant 2026?
Educational Qualification and Experience
| Requirement | Detail |
|---|---|
| Degree | B.Sc. (Chemistry) or B.Pharm from a recognised university |
| Experience | One year of work experience in testing and analysis of drugs |
| Who needs the experience | Both B.Sc. (Chemistry) and B.Pharm holders |
| Nationality | Citizen of India |
If you are a science graduate without the drug-testing experience, you are not eligible for this post. For candidates who pass the written exam, the Commission will check the validity of this mandatory 1-year experience certificate in consultation with the department, so get it from a genuine laboratory.
The notification does not limit this eligibility experience to government labs. The extra 25 marks and the contract-service age relaxation, however, are only for contract service on an equivalent post in a non-private lab in Bihar. Service on daily wages or through an outsourcing agency does not count; Annexure-I must certify this.
Age Limit (as on 01 August 2026)
| Category | Minimum Age | Maximum Age |
|---|---|---|
| Unreserved (Male) | 21 years | 37 years |
| Unreserved (Female) | 21 years | 40 years |
| BC / EBC (Male and Female) | 21 years | 40 years |
| SC / ST (Male and Female) | 21 years | 42 years |

| Age Relaxation | Benefit on Maximum Age |
|---|---|
| PwBD (Divyang) | 10 years |
| Regularly appointed Bihar government servants with 3 years of continuous service | 5 years (for moving to a higher pay scale) |
| Contract Scientific Assistant or equivalent in a non-private lab in Bihar | Equal to your contract service period, part years included (cut-off 01.08.2026); only for regular appointment on the same post |
| Ex-Servicemen | 3 years plus defence service, if actual age is not above 57 years on the date of application; certificate compulsory |
Your date of birth is taken only from your Matriculation or equivalent certificate. You can claim only one of these relaxations, not two together.
What is the Salary for BTSC Scientific Assistant 2026?
The notification places the post at Pay Level-5 of the Bihar government pay structure.
| Component | Detail |
|---|---|
| Post | Scientific Assistant |
| Pay | Pay Level-5 |
| Nature of job | Regular appointment |

What is the Selection Process for BTSC Scientific Assistant 2026?
The Commission selects candidates on the basis of the written competitive exam and work experience.
| Stage | Detail |
|---|---|
| Computer Based Test (CBT) | Weightage of 75 marks |
| Contract experience weightage | Up to 25 marks: 5 marks per year of satisfactory contract service on an equivalent post in a non-private lab in Bihar (part years pro-rata: working days × 5 ÷ 365) |
| Final score | 100 marks (CBT 75 + experience 25), ranked category-wise |
| Document Verification | For candidates who qualify the written exam |
| CBT Pattern | Detail |
|---|---|
| Questions | 100 multiple-choice objective questions |
| Language | Hindi and English |
| Duration | 2 hours |
| Maximum Marks | 400 |
| Marking | +4 for each correct answer, −1 for each wrong answer |
| Conversion | CBT percentage × 0.75 (e.g. 50% gives 37.5 marks) |
| Shifts | Held in more than one shift; results will be normalised |
| Syllabus | Set by the department; to be published separately on the Commission website |
| Category | Minimum Qualifying Marks in CBT |
|---|---|
| General | 40% |
| BC | 36.5% |
| EBC | 34% |
| SC / ST, Women and PwBD | 32% |
| Candidates domiciled outside Bihar (including women and PwBD) | 40% |
Yes, there is negative marking, so avoid blind guessing. The experience marks count only if you pass the written exam, and only when the certificate is in the Annexure-I format; any other format gets no marks and no age relaxation. Experience is counted up to 25 September 2026. A simple example: if you score 60% in the CBT, you get 60 × 0.75 = 45 marks. Two full years of contract service add 10 marks, which takes you to 55 out of 100. Keep checking our syllabus section once BTSC publishes the syllabus.
