- Eligibility: You must have a Master’s degree (or equivalent) in a CSIR‑recognised subject, be a citizen of India, and satisfy age & educational criteria.
- Exam Pattern: It is a 3‑hour computer‑based test with 100 multiple‑choice questions, 2 marks per correct answer, –0.5 for a wrong answer, and 0 for an unattempted question.
2. Key Points
| Aspect | Details |
|---|---|
| Exam Conducting Body | CSIR – Council of Scientific & Industrial Research |

| Eligibility – Year of Graduation | Degree must be awarded no more than 5 years prior to the declaration of the exam results. |
| Eligibility – Other Prerequisites | • No prior CSIR NET JRF attempt • No other CSIR fellowship (e.g., CSIR‑NET PhD) before the current attempt |
| Exam Pattern | • 100 MCQs (4 options each) in 3 hrs (180 min) • 2 marks for a correct answer • –0.5 marks for a wrong answer (negative marking) • 0 marks for unattempted question |
| Subjects Covered | 1. Biology (Biochemistry, Microbiology, Biotechnology, etc.) 2. Chemistry (Inorganic, Organic, Physical, etc.) 3. Earth Sciences (Geology, Geophysics, etc.) 4. Engineering & Technology (Chemical Engineering, etc.) 5. Mathematics & Statistics 6. Physics (Applied, Solid State, etc.) 7. Computer Science & Information Technology |
| Marks Distribution | 100 questions × 2 marks = 200 marks total |
| Cut‑Off | Determined by CSIR; usually 70–80 (out of 200) for the “eligible” category. |

3. Worked Example
Scenario – Raj, a 26‑year‑old Indian citizen, holds an M.Sc. (Chemistry) from a recognized university. He graduated 4 years ago. He is preparing to take the CSIR‑NET JRF exam.
| Requirement | Raj’s Status |
|---|---|
| Age 25 ± 2? | 26 → Yes |
| Nationality | Indian citizen → Yes |
| Master’s degree in CSIR‑recognized subject | M.Sc. Chemistry → Yes |
| Degree awarded ≤5 years before result | 4 years ago → Yes |
| Has not attempted CSIR‑NET JRF before | First attempt → Yes |
Conclusion – Raj is eligible to register for the CSIR‑NET JRF exam.
Sample Calculation of Final Score
Suppose Raj answers the 100 questions as follows:
| Item | Count | Marks per item | Total Marks |
|---|---|---|---|
| Correct Answers | 70 | +2 | 140 |
| Wrong Answers | 20 | –0.5 | –10 |
| Unattempted | 10 | 0 | 0 |
| Total | 100 | 130 |
- Score = 140 – 10 = 130 (out of 200).
- If the cut‑off for the year is 70, Raj comfortably surpasses it.
