CSIR NET December 2026 Exam Date and Application Form; CSIR NET June 2026 Result, Cut-off, Life Science Syllabus, Exam Pattern, Eligibility and Free CSIR NET Mock Tests

CSIR NET determines eligibility for the Junior Research Fellowship and for lectureship in the science disciplines — chemical sciences, earth sciences, life sciences, mathematical sciences and physical sciences. It is the science counterpart to UGC NET, conducted for the Council of Scientific and Industrial Research.

Its paper works quite differently from UGC NET, and the difference is worth understanding before you prepare. It is divided into three parts of ascending difficulty and value, with Part C carrying the most marks and asking genuine problem-solving questions rather than recall. It also has negative marking, which UGC NET does not.

Overview

What CSIR NET is, and who it suits

CSIR NET is the eligibility examination for research fellowships and lectureship in the sciences. Successful candidates qualify for the Junior Research Fellowship, which funds doctoral research, or for lectureship eligibility, or for admission to a doctoral programme, according to their score against separately set cutoffs.

The examination runs in five subjects, and candidates choose the one corresponding to their postgraduate discipline. Unlike UGC NET, where a common aptitude paper sits alongside a subject paper, CSIR NET is overwhelmingly a subject examination — Part A is a modest general aptitude section, and Parts B and C are both in your science subject.

The three parts

  • Part A — General Aptitude — common to all five subjects, covering logical reasoning, graphical analysis, analytical and numerical ability, quantitative comparison, series formation and puzzles. Candidates attempt a specified number from a larger set.
  • Part B — Subject, conventional — subject questions of the kind a good postgraduate examination would ask, testing whether you know the discipline.
  • Part C — Subject, higher order — the highest-valued questions, requiring scientific reasoning and application rather than recall. This is where the examination genuinely separates candidates.

You choose which questions to attempt

Each part specifies a maximum number of questions that will be evaluated, drawn from a larger set. That makes question selection an explicit part of the examination rather than an implicit one — you are expected to choose, and choosing well is a skill worth practising.

Eligibility

Who can apply for CSIR NET

Joint CSIR-UGC NET eligibility, from chapter 2 of the June 2026 bulletin (the text is supplied by CSIR). Verification happens at the fellowship or appointment stage, not at application.

Admission to Ph.D.No upper age limit

Also from the bulletin

  • Subject choice — one of the five; the paper of the subject nearest your post-graduation — Life Sciences takes botany, zoology, biochemistry, biotechnology and microbiology graduates, for instance.
  • National fellowships — NFOBC, NFSC and NFPwD aspirants also apply through this examination and are compiled separately by the nodal agencies.
  • Certificate validity — the Assistant Professor eligibility certificate has no end period; the JRF must be taken up within the period in the award letter.

Selection process

How CSIR NET selection works

Each stage in order, and what it actually tests.

Stages change between cycles. Confirm the structure in the notification for the cycle you are sitting.
StageFormatWhat it involves
Part A — general aptitudeObjective, 20 questions, attempt 15, 2 marks each, −0.5 per wrong answerCommon to all five subjects: logical reasoning, graphical analysis, numerical ability, quantitative comparison, series, puzzles. The same 30 marks in every paper.
Part B — subject, single-conceptObjective, 25–50 questions by subject, attempt 20–35, 2–3.5 marks eachConventional questions across the subject syllabus; the questions attempted beyond the limit are ignored in the order marked.
Part C — subject, analyticalObjective, 30–80 questions by subject, attempt 20–25, 4–5 marks eachHigher-value questions testing scientific concepts and their application; this part decides JRF ranks. Negative marking is 25 per cent except Earth Sciences (33 per cent) and Mathematics (none).
Result in three categories with ranksSubject- and category-wise cut-offs on the 200-mark aggregateCategory 1 JRF and Assistant Professor (ranked, split between CSIR and UGC fellowships), Category 2 Assistant Professor and Ph.D. admission, Category 3 Ph.D. only. No part-wise cut-off; a 33 per cent minimum (25 for SC, ST and PwD).

Application to fellowship

How CSIR NET runs, from the NTA form to the CSIR or UGC fellowship

The steps follow the June 2026 bulletin and the notices of that cycle.

The CSIR NET process, from registration to certificate

  1. Register on the NTA portal Applications are online only, on csirnet.nta.nic.in. Registration takes the name, parents’ names and date of birth exactly as on the class-10 certificate, one mobile number and one e-mail address, and generates an application number; the form then takes the category, PwD status, qualifications, the subject and medium, and up to four city choices. Only one application per candidate is accepted — duplicates are cancelled.
  2. Upload the images and pay the fee A recent passport photograph (10–200 KB JPG), a signature in running hand (10–50 KB), and the category, PwD and result-awaited attestation PDFs where they apply. The fee is ₹1,150 for General, ₹600 for EWS and OBC-NCL and ₹325 for SC, ST, PwD/PwBD and third gender, plus bank charges. Payment by debit or credit card, net banking or UPI; the application counts only when the fee transaction succeeds, and the confirmation page should be saved.
  3. Use the correction window NTA opens a two- or three-day correction window after the closing date. Most fields can be edited once; the category, PwD status and subject changes may attract a fee difference. Nothing is changed after the window closes, and NTA does not edit forms on request.
  4. City intimation and admit card An advance city-intimation slip appears about ten days before the examination and the admit card a few days after it, both on the portal; nothing is posted. Carry the admit card, the same photo-ID used in the form, a passport photograph for the attendance sheet and, for PwD candidates, the certificate.
  5. The computer-based test Reporting is about two hours before the shift and the gate closes 30 minutes before the start. The paper runs on a computer with a virtual keyboard; rough sheets are issued and collected. Marked-for-review questions with an option selected are counted as answered.
  6. Answer key challenge and result Provisional answer keys with the recorded responses go up for about three days; a challenge costs ₹200 per question, refundable if the experts accept it, and accepted corrections apply to every candidate. Final keys, then the result and scorecard are hosted on the portal; there is no re-evaluation. E-certificates follow on the portal and DigiLocker.
  7. Ranks, fellowship and joining CSIR HRDG publishes the roll-number lists with JRF ranks on csirhrdg.res.in. JRF qualifiers are split between the CSIR and UGC schemes; the award letter names the scheme, and the fellow joins a university, IIT, national laboratory or recognised institution as a Ph.D. scholar. The stipend is ₹37,000 a month for two years with a ₹20,000 annual contingency grant, rising to ₹42,000 as SRF from the third year on assessment; a fellow not registered for a Ph.D. or not upgraded continues at ₹37,000 for the third year or is terminated on the committee’s recommendation.

Exam pattern

CSIR NET exam pattern and marking

The CSIR NET exam pattern below is chapter 3 of the June 2026 bulletin: one computer-based paper of three hours with no break, in three parts, 200 marks, with a cap on the number of questions evaluated in each part. Questions answered beyond the cap are ignored in the order attempted, so the answer count matters as much as accuracy.

ScorecardTotal percentile and marks; ranks for JRF qualifiers

Mathematics and Physics cut-offs are low because the papers are hard

A JRF in Mathematical Sciences went at 43 per cent and Physical Sciences at 45.9 in June 2026 against 66.5 in Life Sciences; Part C in those papers has 4.75- and 5-mark questions that take ten minutes each. The strategy is selective: 15 clean Part A answers, the Part B cap, and 12–15 sure Part C answers rather than the full 20.

Study plan

How to prepare for CSIR NET

CSIR NET rewards depth in a few units over coverage of all, because Part C questions are worth 4–5 marks each and a candidate only has to answer 20–25 of them. Life Sciences candidates in particular should choose the eight or nine units they will own. Twelve weeks to the December cycle is workable for a fresh M.Sc.

Twelve-week plan for CSIR NET December 2026.

1–2Part A: reasoning, numerical ability, graphs and series from previous papers, 30 minutes a dayPart A at 13–15 correct in 30 minutes

11–12Two full mocks a week with the exact negative marking of your subject; revision of Part C unitsA settled attempt plan for the three hours

What JRF qualifiers do differently

  • They respect the caps — the first 25 Part C answers are the only ones counted, so a doubtful early answer displaces a certain late one.
  • They plan the three hours by marks, not questions — Part C carries 100 of the 200 marks in Life and Chemical Sciences.
  • They know the deduction of their subject — a wrong Part C answer costs 1.32 in Earth Sciences and nothing in Mathematics; the guessing rule differs.
  • They use the CSIR syllabus as the checklist — it is on csirhrdg.res.in and the question paper follows its units closely.

Questions

CSIR NET — FAQs

How is CSIR NET different from UGC NET?

CSIR NET covers the five science subjects — chemical, earth, life, mathematical and physical sciences — while UGC NET covers the humanities, social sciences, commerce and allied disciplines. Structurally, CSIR NET has a three-part paper with ascending difficulty and a small general aptitude component, whereas UGC NET has a full hundred-mark aptitude paper alongside the subject paper. Critically, CSIR NET has negative marking and UGC NET does not, which changes attempt strategy entirely.

Why is CSIR NET Part C so important?

It carries the largest share of the marks and it tests something subject revision does not build. Part B asks whether you know the discipline; Part C asks whether you can use it, typically combining two or three concepts in a problem that requires derivation or multi-step reasoning rather than recall. Two candidates with identical factual knowledge can score very differently here, which is why solving problems — not reading solved ones — should run through the whole preparation rather than being left to the end.

Can I choose which CSIR NET questions to attempt?

Yes, and this is an explicit feature of the examination rather than an accident. Each part specifies a maximum number of questions that will be evaluated, drawn from a larger set, so you decide where to spend a limited attempt budget. That makes triage a genuine skill worth rehearsing under timed conditions, since a candidate who spends the budget on questions that resist them scores worse than one who selects well.

What can I do after qualifying CSIR NET?

Depending on your score against separately set cutoffs, you may qualify for the Junior Research Fellowship, which funds doctoral research; for lectureship eligibility, which permits you to apply for Assistant Professor positions; or for admission to a doctoral programme. As with UGC NET, lectureship eligibility is a precondition for applying rather than an appointment — institutions run their own recruitment processes.

When is the CSIR NET December 2026 exam date, and when does the application form open?

NTA’s examination calendar of 16 September 2026 proposes the Joint CSIR-UGC NET December 2026 for 20 and 21 December 2026; the subject-wise dates and shifts come with the information bulletin. The application form is not yet open — the June 2026 bulletin appeared on 27 May with applications to 19 June, seven weeks before the examination, so the December 2026 form on csirnet.nta.nic.in is expected in October 2026 with about three weeks to apply. The June 2026 scores came on 29 August and the result, ranks and cut-offs on 10 September 2026.

What is the CSIR NET Life Science syllabus?

Thirteen units, unchanged for years: molecules and their interaction relevant to biology; cellular organisation; fundamental processes; cell communication and cell signalling; developmental biology; system physiology of plants; system physiology of animals; inheritance biology; diversity of life forms; ecological principles; evolution and behaviour; applied biology; and methods in biology. Part A is the general aptitude common to all five subjects; Parts B and C draw on all thirteen units, with Part C’s analytical questions concentrated in cell biology, molecular biology, genetics, physiology and ecology. Life Sciences is the largest paper — 83,546 registered in June 2026 — and the syllabus PDF is on csirnet.nta.nic.in and on the CSIR NET syllabus page here.

How do I check the CSIR NET answer key 2026?

On csirnet.nta.nic.in with the application number and date of birth. For June 2026 the provisional keys and recorded responses were displayed from 10 to 18 August with a challenge fee of ₹200 per question, the final keys and scores came on 29 August, and the result with ranks and cut-offs on 10 September 2026. Expect the December 2026 keys three to four weeks after the 20–21 December examination.

What is the CSIR NET exam pattern?

One computer-based paper of three hours and 200 marks in three parts. Part A (general aptitude): 20 questions, attempt 15, two marks each. Part B: 25–50 subject questions, attempt 20–35, two to 3.5 marks each. Part C: 30–80 analytical subject questions, attempt 20–25, four to five marks each. Negative marking is 25 per cent of the question’s marks in most parts, 33 per cent in Earth Sciences Part C and none in Mathematical Sciences Part C.

What was the CSIR NET June 2026 cut-off?

For JRF, unreserved: Chemical Sciences 62.25 per cent, Earth Sciences 71.02, Life Sciences 66.50, Mathematical Sciences 43.00 and Physical Sciences 45.875 of 200 marks. Assistant Professor cut-offs were 56.03, 63.92, 59.85, 38.70 and 41.29, and Ph.D.-only 46.25, 54.88, 50.25, 33.00 and 34.94. OBC-NCL JRF lines ran 55–65 per cent in the three large sciences and SC 43–56.

How many candidates qualified CSIR NET June 2026?

3,308 for JRF — 1,433 under the CSIR scheme and 1,875 under UGC, including 39 JRF-only qualifiers on a four-year degree — 4,167 for Assistant Professor and Ph.D. admission, and 12,552 for Ph.D. admission only, from 1,50,057 who appeared out of 1,87,739 registered. Life Sciences alone had 67,650 candidates.

Who is eligible for CSIR NET, and what is the age limit?

An M.Sc. or equivalent — including integrated BS-MS, B.Pharm, MBBS and BE/B.Tech — with 55 per cent (50 for OBC-NCL, SC, ST, PwD and third gender) or in the final year, or a four-year bachelor’s with 75 per cent for JRF and Ph.D. only. JRF applicants must be 30 or under on 1 July 2026 for the June cycle, with up to five years’ relaxation for reserved categories, women and research experience; Assistant Professor and Ph.D. eligibility carry no age limit.

Is there negative marking in CSIR NET?

Yes, in most parts: a quarter of the question’s marks for a wrong answer in Parts A and B of every subject and in Part C of Chemical, Life and Physical Sciences (0.5, 0.5–0.875 and 1–1.25 marks respectively), a third (1.32 marks) in Earth Sciences Part C, and none in Mathematical Sciences Part C. Only the capped number of answers per part is evaluated.

What is the CSIR NET JRF stipend?

₹37,000 a month for the first two years plus an annual contingency grant of ₹20,000 paid to the fellow, then ₹42,000 a month as SRF from the third year on assessment by a committee, provided the fellow has registered for a Ph.D. The number of fellowships per subject is limited and varies by cycle; JRF qualifiers are ranked and split between the CSIR and UGC schemes.

Are there free CSIR NET mock tests?

Yes. The free CSIR NET mock tests here follow the June 2026 pattern of your subject — the three parts with their attempt caps, marks and the exact negative marking, in three hours on screen — and score the paper the way NTA does, discarding answers beyond the cap, against the June 2026 cut-off of your category.
