Eligibility Criteria

CriterionDetail
Educational QualificationB.Sc with Chemistry, or B.Pharm, from a recognised university
Work ExperienceAt least 1 year of work experience in testing and analysis of drugs — compulsory for both B.Sc and B.Pharm candidates
Age LimitMinimum 21 years as on 01.08.2026. Your date of birth is taken from your Matriculation (Class 10) certificate.
Check your age eligibility →
NationalityIndian citizen
ReservationOnly for permanent residents (domicile) of Bihar. Candidates from other states can apply, but only as General (Unreserved).
CategoryMaximum Age
Unreserved (men)37 years
Unreserved (women)40 years
BC / EBC (men and women)40 years
SC / ST (men and women)42 years
Persons with Disabilities (PwBD)10 extra years
Regular Bihar government employees with 3 years of continuous service5 extra years
Contract Scientific Assistants (or equal post) in Bihar government or public laboratoriesExtra years equal to your contract service, counted up to 01.08.2026
Ex-Servicemen3 years plus your years of defence service, but your actual age must not be above 57 on the day you apply

In short: the extra relaxations in the last four rows do not stack — you can use only one of them on top of your category limit. So a 45-year-old BC candidate with 6 years of contract lab work in Bihar still qualifies, but a disability relaxation and a contract-service relaxation cannot be added together.

Not sure whether you are within the age limit?
Enter your date of birth, the 01.08.2026 cut-off date and your category to see instantly whether you fall inside the 21 to 37 year band (or up to 42 with relaxation).

Selection Process

StageDetails
1. Computer-Based Test (CBT)An online exam you take on a computer at a test centre. 100 multiple-choice questions in Hindi and English, 2 hours, 400 marks. 4 marks for each right answer and 1 mark cut for each wrong one. The syllabus will be put up separately on the BTSC website.
NormalisationIf the exam runs in more than one shift, scores are adjusted (normalised) so that candidates who got an easier or harder shift are compared fairly.
Converting to 75 marksYour percentage in the CBT is multiplied by 0.75. For example, 50% in the exam becomes 37.5 marks out of 75.
Minimum qualifying marksGeneral 40%, BC 36.5%, EBC 34%, SC/ST, women and PwBD 32%. Candidates from outside Bihar need 40% whatever their category.
2. Work experience marks (up to 25)5 marks for each year of satisfactory contract service on an equal post in a Bihar government or public laboratory (central government, Bihar government, municipal bodies, panchayati raj bodies, military labs and similar). Part of a year counts pro-rata. Given only if you pass the CBT, and only with a certificate in the Appendix-I format.
3. Document VerificationQualified candidates are placed in a category-wise merit list out of 100 and called to show original certificates.

In plain terms: the written exam decides most of your rank, and the experience marks only help people who have already worked on contract in a Bihar government lab. The one year of drug-testing experience needed to apply is a separate thing — it makes you eligible but does not earn marks by itself.

Salary and Benefits

The notification places the post in Pay Level 5. A Pay Level is a fixed grade on the government pay chart; Level 5 starts at a basic pay of Rs 29,200 a month and goes up to Rs 92,300 over the years. Dearness Allowance, House Rent Allowance and other benefits are added as per Bihar government rules — the notification itself does not list them.

Common Mistakes to Avoid

  • Applying without the 1-year drug testing experience — a B.Sc or B.Pharm degree alone does not make you eligible.
  • BC and EBC candidates uploading only a caste certificate; without a valid Non-Creamy Layer certificate the reservation is refused.
  • Forgetting to tick your category, disability or freedom-fighter box in the form — the benefit is lost, and the category cannot be changed after registration.
  • Uploading a blurred or dark scan; BTSC can cancel your candidature for unreadable documents even at document verification.
  • Getting a contract experience certificate in any format other than Appendix-I — no marks or age relaxation will be given for it.
  • Leaving the form for the last day; BTSC is not responsible for internet or payment failures.
