The Bihar Technical Service Commission (BTSC) has released Advertisement No. 30/2026 for regular appointment to the post of Scientific Assistant (वैज्ञानिक सहायक) under the Bihar Drug Control Laboratory Technical Staff Cadre of the Health Department, Government of Bihar.
The notification requires candidates to have either a B.Sc. in Chemistry or B.Pharm from a recognized university along with one year of experience in testing and analysis of drugs. The post carries Pay Level-5.
Online applications are invited from 25 September 2026 to 24 October 2026 through the BTSC application system. The official BTSC recruitment page also lists Advertisement No. 30/2026 as the recruitment for Scientific Assistant and confirms the same application dates.
This guide explains the vacancy details, qualification, mandatory experience, age limit, reservation, application fee, CBT pattern, experience marks, qualifying marks, documents and online application process.
Important vacancy note: The scanned notification’s vacancy table shows a main category-wise row totaling 6 posts. A separate second row in the table also displays 01 under UR/Total, but its row label is not clearly readable in the scanned PDF. Current BTSC recruitment listings and multiple current reports treat the advertised Scientific Assistant vacancy as 6 posts. Therefore, this article uses 6 as the main advertised vacancy figure and does not silently add the unlabeled row to the total. Candidates should check any later BTSC clarification/update before applying.

BTSC Scientific Assistant Vacancy 2026
The main vacancy roster in the notification shows 6 posts distributed across the following categories:
| Category | Vacancies |
|---|---|
| Unreserved (UR) | 3 |
| Economically Weaker Section (EWS) | 0 |
| Scheduled Caste (SC) | 1 |
| Scheduled Tribe (ST) | 0 |

Vacancy-table clarification
The scanned notification contains a second line beneath the six-post roster showing 01 under UR and 01 under Total, but the corresponding row heading is not clearly visible/readable in the supplied scan. Because the official BTSC recruitment listing names the recruitment but does not publish the vacancy number in its text listing, and current recruitment reporting predominantly treats the main advertised count as six, this article does not present that unlabeled line as an additional confirmed vacancy.
Candidate advice: Check the latest BTSC notice before final submission in case the Commission clarifies or revises the requisition.
BTSC Scientific Assistant Eligibility 2026
Educational Qualification
Candidates must possess either:
- B.Sc. in Chemistry from a recognized university, or
- B.Pharm from a recognized university.
However, the degree alone is not sufficient.
The notification specifically requires one year of work experience in testing and analysis of drugs. It also clearly states that this experience requirement applies to candidates having either of the prescribed educational qualifications.
Simple Eligibility Check
| Qualification | 1-Year Drug Testing & Analysis Experience | Basic Eligibility |
|---|---|---|
| B.Sc. Chemistry | Required | Yes, subject to other conditions |
| B.Pharm | Required | Yes, subject to other conditions |
| B.Sc. Chemistry without required experience | No | Not eligible |
| B.Pharm without required experience | No | Not eligible |
| Unrelated graduation | — | Not eligible under the stated qualification |
Important: Do not treat retail pharmacy experience, unrelated laboratory work or general work experience as automatically equivalent to the required drug testing and analysis experience. The notification specifically requires experience in testing and analysis of drugs.
What Experience Is Required?
The essential experience requirement is:
One year of experience in testing and analysis of drugs.
The notification also provides a separate mechanism for contractual work experience marks in the final merit. This is different from the basic one-year essential experience requirement.
This distinction is important:
Essential Experience
Every applicant must satisfy the prescribed one-year drug testing and analysis experience requirement.
Additional Experience Marks
Eligible contractual experience can provide up to 25 additional merit marks, subject to the conditions and prescribed certificate format in the notification.
Therefore, candidates should not assume that the 25-mark experience component replaces the mandatory one-year qualification experience.
BTSC Scientific Assistant Age Limit 2026
The age is calculated as on 01 August 2026.
| Candidate Category | Minimum Age | Maximum Age |
|---|---|---|
| Unreserved Male | 21 Years | 37 Years |
| Unreserved Female | 21 Years | 40 Years |
| BC / EBC | 21 Years | 40 Years |
| SC / ST | 21 Years | 42 Years |
The notification states the minimum age as 21 years on 01 August 2026 and specifies maximum ages of 37 years for unreserved candidates, 40 years for unreserved women and BC/EBC candidates, and 42 years for SC/ST candidates.
Age Relaxation for BTSC Scientific Assistant
The notification provides additional age-related provisions for specific categories and service backgrounds.
These include provisions concerning:
- PwBD candidates
- Regular government employees meeting the prescribed service conditions
- Candidates working on contract in eligible institutions/laboratories
- Ex-servicemen
- Other applicable Government rules
For contractual candidates, the notification provides age-relaxation provisions linked to the duration of qualifying contractual service, subject to the stated conditions.
Important
Candidates should claim only the relaxation for which they have valid supporting documents. The notification also makes clear that more than one applicable age relaxation cannot simply be combined beyond the permitted rules.
BTSC Scientific Assistant Salary 2026
The notification specifies:
Pay Level-5
It does not print a separate rupee salary range in the supplied advertisement.
| Particular | Details |
|---|---|
| Post | Scientific Assistant |
| Pay Level | Level-5 |
| Exact Rupee Pay Range in Advertisement | Not specified in the provided notification. |
As an additional reference, Level-5 in the standard 7th CPC pay matrix starts at ₹29,200 basic pay, but this exact rupee figure is not printed in the uploaded BTSC advertisement. Current third-party recruitment references also associate Level-5 with ₹29,200 starting basic pay.
For the article, it is safer to present Level-5 as the official notified pay information and avoid promising an exact in-hand salary.
BTSC Scientific Assistant Application Fee 2026
The application fee is ₹100.
| Particular | Fee |
|---|---|
| Application Fee | ₹100 |
| Payment Mode | Online Only |
The notification states that the ₹100 examination/application fee is to be paid through online mode only, with applicable bank/payment charges borne separately by the candidate.
BTSC Scientific Assistant Important Dates 2026
The official BTSC recruitment listing gives the following application schedule for Advertisement No. 30/2026.

| Online Registration Start | 25 September 2026 |
| Last Date to Apply Online | 24 October 2026 |
| Last Date for Fee Payment | 24 October 2026 |

The official BTSC recruitment page currently lists Advertisement No. 30/2026 with registration from 25 September to 24 October 2026, with the application and payment deadlines also on 24 October.
BTSC Scientific Assistant Selection Process 2026
The selection structure has two merit components:
- Computer Based Test – 75 marks
- Eligible contractual work experience – up to 25 marks
The final merit framework therefore has a maximum of 100 marks.
| Selection Component | Maximum Merit Marks |
|---|---|
| Computer Based Written Examination | 75 |
| Eligible Contractual Work Experience | 25 |
| Total | 100 |
The notification states that qualified candidates are subsequently considered for document verification according to the applicable procedure.
BTSC Scientific Assistant Exam Pattern 2026
The written competitive examination will be conducted through a Computer Based Test (CBT).
According to page 4 of the notification:
- 100 objective questions
- 400 total marks
- 2 hours
- Question paper in Hindi and English
- +4 marks for each correct answer
- -1 mark for each incorrect answer
The notification also provides for normalization where the examination is conducted in multiple shifts.
| Exam Particular | Details |
|---|---|
| Mode | Computer Based Test (CBT) |
| Total Questions | 100 |
| Question Type | Objective / Multiple Choice Questions |
| Maximum Raw Marks | 400 |
| Duration | 2 Hours |
| Language | Hindi and English |
| Correct Answer | +4 Marks |
| Wrong Answer | -1 Mark |
| Normalization | Applicable where required for multiple shifts |
How CBT Marks Are Converted Into Final Merit
The CBT has a maximum of 400 raw marks, but only 75 merit marks are assigned to the written examination.
The notification provides the conversion method based on the percentage obtained in the written examination.
Example from the Notification
If a candidate obtains 50% in the written examination:
50 × 0.75 = 37.5 merit marks
So, 50% in the CBT contributes 37.5 out of 75 marks to the final merit.
This is important because candidates should not confuse the 400 raw examination marks with the 75 final merit marks.
BTSC Scientific Assistant Minimum Qualifying Marks
The notification specifies different minimum qualifying percentages for different categories.
| Category | Minimum Qualifying Percentage |
|---|---|
| General / Unreserved | 40% |
| Backward Class (BC) | 36.5% |
| Extremely Backward Class (EBC) | 34% |
| SC / ST / Women / PwBD | 32% |
| Candidates Outside Bihar | 40% |
The notification states that candidates must obtain the prescribed minimum qualifying percentage according to their applicable category. It also specifies 40% for candidates residing outside Bihar, including women and PwBD candidates.
Contractual Work Experience Marks
Eligible contractual experience can contribute up to 25 marks to final merit.
The notification provides the experience component at the rate of up to 5 marks per year, subject to the prescribed calculation and maximum of 25 marks.
However, this benefit is subject to specific conditions.
The candidate must:
- Qualify the written competitive examination.
- Claim the experience in the online application.
- Submit the prescribed experience certificate.
- Ensure that the experience meets the notification’s eligibility conditions.
The notification provides a prescribed Annexure-I format for candidates claiming contractual experience marks.
Important Difference
Mandatory one-year drug-testing experience = eligibility condition.
Eligible contractual experience marks = additional merit component.
These should not be treated as the same thing.
Is Interview Required?
The uploaded Advertisement No. 30/2026 does not specify an interview stage in the selection framework.
The stated merit structure is:
CBT – 75 Marks + Eligible Contractual Experience – 25 Marks = 100 Marks
Candidates who qualify as required are then considered for document verification.
Therefore, candidates should not assume that an interview will be conducted unless BTSC publishes a subsequent notice adding or clarifying such a stage.
BTSC Scientific Assistant Syllabus 2026
The uploaded notification gives the CBT structure but does not provide a detailed topic-wise syllabus.
Therefore:
Detailed syllabus: Not specified in the provided notification.
The notification indicates that the examination syllabus will be based on the requirements of the concerned department and that further information is to be published through the Commission’s website.
Candidates should use the official BTSC website for the separately published syllabus rather than relying on an unofficial topic list.
BTSC Scientific Assistant Exam Date 2026
The notification does not specify the CBT examination date.

|---|---|
