Rajasthan Subordinate and Ministerial Services Selection Board Lab Assistant

RSSB Lab Assistant is the Rajasthan state recruitment for Lab Assistant and Junior Lab Assistant posts in government schools, colleges, the forensic science laboratory and other departments. It is conducted by the Rajasthan Staff Selection Board (RSSB), which many students still search for by its older name, RSMSSB. The latest cycle, the Lab Assistant and Junior Lab Assistant Direct Recruitment 2026, was notified for 804 posts under Advertisement No. 05/2026.

The 2026 written exams were held in May 2026, the result came out on 14 August 2026, and document verification followed in September and October. This page covers the whole recruitment in one place: posts by department, eligibility, the two separate exam patterns for Science and Geography posts, the syllabus at a glance, pay, the 2026 cut-off and a preparation plan you can start now for the next cycle.

Lab Assistant Recruitment 2026: Notification and Current Status

The 2026 notification was the first Lab Assistant recruitment from the board since the 2022 cycle. It combined posts from six departments into one exam, which is why the eligibility and the exam paper depend on the post you apply for.

• Two streams, two different papers: Science posts (Lab Assistant and Junior Lab Assistant) take two papers of 200 marks each. Geography posts in College Education take a single 300-mark paper. Many pages show only the Science pattern, so check which stream your post falls under.

• One Time Registration: Applications were accepted only through the SSO portal, and candidates had to complete RSSB's One Time Registration (OTR) first.

• Result and next step: The board released the merit-wise result and cut-off for document verification on 14 August 2026. Shortlisted candidates submitted the detailed application cum scrutiny form from 17 to 31 August 2026 and then attended document verification.

If you missed this cycle, use the details below as your reference for the next notification. The structure of the exam has stayed broadly stable, but always confirm the pattern in the new advertisement.

Important Dates

Dates for the next cycle will appear in a fresh notification. Track the news and notices section of the official RSSB website and your registered email and mobile number, since admit cards and DV schedules are announced there first.

Vacancy Details by Department

The 804 posts are split between Non-TSP and TSP (Scheduled Area) quotas. The Secondary Education department alone accounts for 500 posts, so most Science applicants are competing for school laboratory roles.

Category-wise splits within each department are given in the notification. Vacancies can be revised before final selection, so treat the figures as advertised numbers, not final appointments.

Eligibility Criteria

Educational Qualification

Every post needs Senior Secondary (10+2) from a recognised board, but the required subjects differ by department. All candidates also need working knowledge of Hindi written in Devanagari script and knowledge of Rajasthani culture.

This is a summary. The exact wording, including accepted computer certificates for forensic posts, is in the official notification, and that wording decides your eligibility at document verification.

Age Limit and Relaxation

Candidates must be between 18 and 40 years of age as on 1 January 2027. Upper age relaxation follows Rajasthan government rules.

Reserved-category relaxation applies only to Rajasthan domicile candidates. Candidates from other states apply as General. You can read the full rules on our RSSB Lab Assistant eligibility page.

Application Fee and How to Apply

The fee is tied to the board's One Time Registration, and an application without a valid OTR is not accepted. The process in 2026 worked like this:

1. Log in to the Rajasthan SSO portal and open the Recruitment Portal.

2. Complete or update your One Time Registration and pay the fee if it is due.

3. Select the Lab Assistant and Junior Lab Assistant recruitment and choose your posts and department preferences.

4. Upload your photograph and signature, check every field, and submit.

5. Save the application printout for document verification.

Common problems at document verification include a qualification that does not match the chosen post, a category certificate that is not valid on the required date, and details in the OTR that do not match your documents. Check these before you submit.

RSSB Lab Assistant Exam Pattern

The exam is objective and OMR-based, with one-third of a question's marks deducted for each wrong answer. The pattern depends on your stream.

Science Posts: Lab Assistant and Junior Lab Assistant

Geography Posts: Lab Assistant (Geography)

To appear in the merit list, you must reach the minimum qualifying marks set in the notification. Most reports cite 40 percent, and 35 percent for SC and ST candidates. Confirm the exact rule in the official notification before setting your targets.

What This Means for You

• Science papers reward accuracy: Each question is worth 2 marks, so a wrong guess costs about 0.67 marks. Three wrong guesses wipe out one correct answer.

• Geography is a speed test: 300 questions in 180 minutes leaves about 36 seconds per question. Practise full-length timed papers, not just topic sets.

• Rajasthan GK is common to both streams: It is a full paper for Science candidates and one-third of the Geography paper, so it deserves daily revision.

Syllabus Summary

The official syllabus names Educational Psychology as a unit without detailed sub-topics, so plan it from standard teacher-exam topics. The complete topic checklist is on our RSSB Lab Assistant syllabus page.

Selection Process

1. Written exam: Science candidates take Paper 1 and Paper 2; Geography candidates take the single Part A and Part B paper. Marks from the written exam decide merit.

2. Merit list for DV: The board shortlists candidates category-wise and area-wise (Non-TSP and TSP) above the minimum qualifying marks.

3. Detailed application and document verification: Shortlisted candidates fill the scrutiny form online and then present original documents.

4. Final selection and allocation: Posts and departments are allotted on merit and preference, subject to eligibility for the chosen post.

There is no interview or skill test, so the written exam score is what gets you the post.

Salary and Pay Level

Newly appointed candidates serve a two-year probation, during which they receive a fixed monthly remuneration set by the state government instead of the full pay scale. After probation, they move to the regular pay matrix with dearness allowance and other allowances. In-hand salary varies with posting and allowances, so any figure you see online is an estimate, not an official number.

Previous Cut-off Reference

The board published merit-wise cut-off marks for document verification with the 2026 result. The figures below are as reported from that list for the Non-TSP area, general sub-category in each category. Science marks are out of 400, and Geography marks are out of 300.

Cut-offs change every year with difficulty, vacancies and the number of applicants. Treat these figures as a benchmark only, check them against the official PDF, and aim for a clear margin above them. The RSSB Lab Assistant cut-off page has the TSP and sub-category figures.

How to Prepare for RSSB Lab Assistant

The 2026 General cut-off for Science was about 66 percent of the total, and for Geography close to 79 percent. That level is reached through steady coverage and many timed papers, not last-minute reading.

For Science Candidates

• Start with Paper 2 concepts: Use Class 11 and 12 textbooks for Physics, Chemistry and Biology. Biology and Chemistry have more factual questions, so they are faster to score in.

• Revise Rajasthan GK daily: Spend 45 to 60 minutes on history, culture and geography of Rajasthan, and keep monthly notes for state current affairs.

• Do not skip Educational Psychology: It is a small but predictable part of Paper 1. Learning theories, child development and intelligence are the usual focus.

For Geography Candidates

• Build on NCERT geography: The Part B topics follow senior secondary physical, Indian, human and practical geography closely.

• Practise map work: Projections, scales, topographic sheets and weather instruments are scoring if you have solved enough questions.

• Train for speed: Take full 300-question papers in three hours at least once a week in the final two months. Timed online tests on Testkart help you check whether your pace is holding up across all 300 questions.

Use Mock Tests and Previous Papers

Previous year papers from the 2022 and 2026 cycles show you the real level of Rajasthan GK and science questions. For timed practice, you can attempt online tests for Rajasthan government exams on Testkart and use the section-wise analysis to see where you lose marks. Keep an error log of every wrong and skipped question, and revise it every week. As the next notification gets closer, shift to full-length papers in the exact pattern of your stream, so that the 2-hour or 3-hour timing feels routine on exam day.
