Laboratory Assistant (Prayogshala Sahayak) is recruited by the Rajasthan Staff Selection Board, Jaipur. The board's syllabus document actually covers three separate recruitments, each with its own scheme — check which one you are applying for before you plan.
1. Lab Assistant (Science) — Combined Direct Recruitment
| Paper | Questions | Marks | Duration |
|---|---|---|---|
| Paper-I : General Knowledge | 100 | 200 | 2 hours |
| Paper-II : Science | 100 | 200 | 2 hours |
| Total | 200 | 400 |
Paper-I covers the geographical, historical and cultural general knowledge of Rajasthan, current affairs of Rajasthan, general knowledge of the world and India, and Educational Psychology.
Paper-II covers science at Secondary level, plus Biology, Physics and Chemistry at Senior Secondary level.
2. Lab Assistant (Geography) — College Education Commissionerate
| Part | Marks | Total | Duration |
|---|---|---|---|
| Part-A : General Knowledge | 100 | 300 | 3 hours |
| Part-B : Geography | 200 |
3. Lab Assistant (Home Science) — College Education Commissionerate
| Part | Marks | Total | Duration |
|---|---|---|---|
| Part-A : General Knowledge | 100 | 300 | 3 hours |
| Part-B : Home Science | 200 |
Rules that apply to all three
The notes are identical in all three notifications:
- All questions in every paper are objective (multiple choice) and carry equal marks.
- A minimum of 40 per cent is fixed as the qualifying mark. Candidates scoring below this are not eligible for appointment.
- Negative marking : one-third (1/3) is deducted for every wrong answer.
Two things worth noticing
- The 40% floor is not a formality. With one-third negative marking, guessing your way to a number is a real risk — a paper can fall below 40% even when it feels answered.
- The Science recruitment has two papers of 200 marks each, while the two College Education posts have a single 300-mark paper split into two parts. The subject weightage is completely different, so use the right one.
