Overview
CSIR NET is the national-level eligibility test administered by NTA on behalf of the Council of Scientific & Industrial Research, determining eligibility for Junior Research Fellowship (JRF) funding and Assistant Professor/Lectureship roles at Indian universities and research institutions. It's conducted twice a year across five science disciplines — Chemical Sciences, Earth/Atmospheric/Ocean/Planetary Sciences, Life Sciences, Mathematical Sciences, and Physical Sciences — with each discipline having its own single, computer-based paper combining general research aptitude with deep subject-specific content, testing genuine postgraduate-level scientific understanding.
What's New in the 2026 Cycle
What changed in the 2026 cycle
- Conducted twice yearly, with candidates choosing one of five science disciplines relevant to their postgraduate specialisation.
- A single JRF-qualifying score also confers Assistant Professor/Lectureship eligibility, but not vice versa — Lectureship-only qualifiers don't receive JRF funding.
- JRF award comes with a fellowship stipend and is typically valid for pursuing a PhD at a recognised institution, subject to admission.
- Paper structure blends a common-format Part A (general aptitude) with discipline-specific Parts B and C at increasing depth and difficulty.
Eligibility Criteria
| Criterion | Details |
|---|---|
| Age Limit | JRF: up to 28 years (relaxation for reserved categories); no upper age limit for Assistant Professor/Lectureship-only eligibility |
| Educational Qualification | Master's degree (or equivalent) in the relevant science discipline (Chemical Sciences, Earth/Atmospheric/Ocean/Planetary Sciences, Life Sciences, Mathematical Sciences, or Physical Sciences) with a minimum aggregate as per CSIR norms; final-year students may apply provisionally |
| Nationality | Indian citizen |
| Application Fee | As specified in the current NTA notification (category-dependent, typically in the ₹500–₹1,150 range) |
CSIR NET Exam Pattern
The CSIR NET selection process runs through single computer-based test. Each stage has its own timing, marking scheme and qualifying rules, detailed below.
CSIR NET (Single Paper, Discipline of Choice)
| Section | Questions | Marks |
|---|---|---|
| Part A — General Aptitude (common to all disciplines) | 20 | 30 |
| Part B — Discipline-specific (moderate difficulty) | — | 70 |
| Part C — Discipline-specific (higher-order, application-based) | — | 100 |
CSIR NET Detailed Subject-Wise Syllabus
Below is the complete topic-wise CSIR NET syllabus for every subject tested across all stages, with a short note on what each section actually rewards — use this to build a section-wise study plan rather than relying on generic topic summaries.
Part A — General Aptitude (common to all disciplines)
A comparatively easier, high-return section relative to preparation time required — don't neglect it.
- General science, quantitative reasoning & analysis
- Research aptitude
- Graphical analysis & numerical ability
- Logical reasoning
Life Sciences (discipline-specific, example)
Extremely broad — prioritise topics with recurring weightage across previous years' papers.
- Molecules & their interaction relevant to biology
- Cellular organisation
- Fundamental processes — DNA replication, transcription, translation
- Cell communication & signalling
- Developmental biology
- System physiology (plant & animal)
- Inheritance biology
- Diversity of life forms
- Ecological principles
- Evolution & behaviour
- Methods in biology & applied biology
Chemical Sciences (discipline-specific, example)
Rewards genuine mechanistic understanding over memorisation, especially in Organic Chemistry.
- Inorganic chemistry — structure, bonding, main group elements
- Physical chemistry — quantum chemistry, thermodynamics, kinetics
- Organic chemistry — reaction mechanisms, stereochemistry, spectroscopy
- Interdisciplinary topics relevant to chemical sciences
Mathematical Sciences (discipline-specific, example)
Demands rigorous, proof-level understanding — this isn't an exam for surface-level formula recall.
- Analysis — real & complex
- Linear algebra
- Abstract algebra
- Topology
- Ordinary & partial differential equations
- Numerical analysis & probability
Physical Sciences (discipline-specific, example)
Mathematical methods and classical mechanics form the foundation most other topics build on — master these first.
- Mathematical methods of physics
- Classical mechanics
- Electromagnetic theory
- Quantum mechanics
- Thermodynamics & statistical physics
- Electronics & experimental methods
- Atomic, molecular, condensed matter, nuclear & particle physics
Selection Process
- Single computer-based paper in the candidate's chosen discipline.
- Merit determined by discipline-wise and category-wise cut-offs, separately calculated for JRF and Lectureship eligibility.
- JRF-qualified candidates seek PhD admission at a recognised institution to avail the fellowship; Lectureship-qualified candidates become eligible to apply for Assistant Professor positions.
Salary & Job Profile
CSIR NET itself carries no direct salary. JRF awardees receive a fellowship stipend (revised periodically by the government, typically in the range of ₹37,000–₹42,000 per month for the initial JRF period, rising for the Senior Research Fellowship phase), while Lectureship-qualified candidates' pay depends on the specific Assistant Professor position and institution they're eventually hired into.
Best Books for CSIR NET Preparation
- Discipline-specific standard postgraduate textbooks (e.g. Molecular Biology of the Cell for Life Sciences; standard inorganic/organic/physical chemistry texts for Chemical Sciences)
- CSIR NET Previous Year Solved Papers — discipline-wise (various publishers)
- CSIR NET Part A — General Aptitude practice guides
- Discipline-specific CSIR NET preparation books — Arihant/MTG/Career Endeavour, as applicable
Previous Cut-off Trends
Approximate — always verify officially
CSIR NET cut-offs vary significantly by discipline, category and cycle, with JRF cut-offs typically set higher than Lectureship-only cut-offs within the same discipline. Always check the official discipline-wise and category-wise cut-off release for the specific cycle.
Preparation Tips
- Focus the bulk of your preparation on Part C's higher-order, application-based questions, since this section carries the most marks and the greatest difficulty differentiation.
- Revise your core Master's-level coursework systematically rather than relying only on CSIR NET-specific guides, since genuine conceptual depth is rewarded.
- Practise previous years' papers extensively to understand the specific style and difficulty calibration of your discipline's paper.
- Don't neglect Part A's General Aptitude section — it's a comparatively easier, high-return section relative to preparation time required.
Exam Day Guidelines
- Carry the Document Checker and a valid original photo ID to the exam centre.
- No electronic devices are allowed inside the exam hall.
- Arrive well before reporting time for biometric verification.
- Since the exam is computer-based, familiarise yourself with the navigation and marking-for-review tools via any available mock link beforehand.
Frequently Asked Questions
A JRF-qualifying score confers both fellowship-funded PhD eligibility and Lectureship eligibility, while a Lectureship-only qualifying score (a lower cut-off) confers only Assistant Professor eligibility, without fellowship funding.
Five — Chemical Sciences, Earth/Atmospheric/Ocean/Planetary Sciences, Life Sciences, Mathematical Sciences, and Physical Sciences — with candidates choosing one based on their postgraduate specialisation.
Twice — each cycle has its own notification, application window and exam date.
No, it confers eligibility only — JRF-qualified candidates must still separately secure PhD admission at a recognised institution, and Lectureship-qualified candidates must separately apply for and be selected in actual Assistant Professor positions.
