CSIR NET Eligibility for Maths: Marks, Age and Degree Rules

You are eligible if you are an Indian citizen with a Master's degree and at least 55% marks (50% for reserved categories), or a four-year bachelor's degree with at least 75%. Candidates still studying can apply provisionally. These are the rules in clause 2.1.1 of the December 2026 bulletin, as of October 2026.

For the Master's route, "reserved categories" means OBC-NCL (Other Backward Classes, non-creamy layer), SC (Scheduled Caste), ST (Scheduled Tribe), PwD/PwBD (persons with disability or with benchmark disability) and Third gender candidates. General and General-EWS (Economically Weaker Section) candidates need 55%.

For a four-year degree, the 75% requirement can fall by 5 percentage points, to 70%, for SC, ST, OBC-NCL, PwBD and EWS candidates, where the relaxation is allowed.

Two smaller points. PhD holders whose Master's was completed by 19 September 1991 need 50% instead of 55%. Integrated BS-MS students (a combined bachelor's and master's programme) can apply as result-awaited Master's candidates, because the Result Awaited Attestation Form (Annexure XI) lists Integrated BS-MS alongside MSc. The June 2025 bulletin carries the same Master's, four-year degree and age wording, so these rules have held across cycles.

Five rules are easy to misread: using 55% for a B.Tech, rounding marks up, using the wrong date for age, stacking age relaxations, and expecting an Assistant Professor appointment from a four-year degree. Each one is settled by a specific clause of the bulletin.

1. 55% is a Master's figure. A BS, B.Tech or BE degree needs 75% under clause 2.1.1(g).
2. Marks are not rounded. The bulletin says "without rounding off". On a 2,000-mark Master's total, 55% is 1,100 marks. A score of 1,098 is 54.9% and fails. This is our arithmetic.
3. Age is measured on a fixed date, not today. It is the 1st of the month in which the exam concludes, which is 1 December 2026 this cycle. In the June 2025 cycle the bulletin used 1 July 2025. A calculator built for another cycle gives wrong answers.
4. Relaxation has a ceiling. All grounds together cannot exceed 5 years, so the highest JRF age is 35.
5. A four-year degree does not lead to an Assistant Professor appointment. The bulletin states that such candidates are not eligible for appointment as Assistant Professor. If you want to be appointed Assistant Professor, you need a Master's.

Yes. Candidates pursuing a Master's, or waiting for a final-year result, can apply and are admitted provisionally. They count as eligible only after passing with 55% (50% for reserved categories) within two years of the NET result, or within one year if they qualify for PhD admission only (clause 2.1.1(b)).

Four-year degree students in their last semester follow the same two-year and one-year deadlines, and must meet the UGC's PhD regulations of 2022 in that time (clause 2.1.1(h)).

You do not send degree mark sheets or any proof of your percentage, and NTA does not verify what you enter. You still upload a category certificate, a disability or Unique Disability ID (UDID) certificate and a result-awaited attestation where they apply. If ineligibility is found at any stage, your candidature is cancelled and you can face legal action, per clause 2.1.1(e).

We recommend doing the arithmetic before you pay the fee. A NET score earned on a degree that finishes below the line does not count. Here is a simple illustration, assuming four semesters of 500 marks each, which is our model since universities weight semesters differently:

• Required: 55% of 2,000 = 1,100 marks.
• Scored after three semesters: 800 of 1,500, which is 53.3%.
• Needed in the last semester: 1,100 − 800 = 300 of 500, which is 60%.

If that final figure looks out of reach, wait for the next cycle.

The JRF age limit is 30 years on the 1st of the month in which the exam concludes, with up to 5 years' relaxation. This is set out in clause 2.1.2(a) of the bulletin. Use these three steps.

1. Fix the reference date. For the December 2026 cycle it is 1 December 2026.
2. Work out your ceiling. Start at 30. Add up to 5 years if you are OBC-NCL, SC, ST, PwD/PwBD, Third gender or a woman. Research experience in a subject related to your Master's (certified, and not done for a degree) or armed-forces service can also add up to 5 years. All relaxations together cannot exceed 5 years.
3. Subtract the ceiling from the reference date. Your date of birth must fall on or after the result.

Someone born exactly on the cut-off date is exactly at the limit on the reference date. We read that as inside "not more than 30 years". If your birthday is within a few days of the line, confirm it with the NTA helpdesk on 011 4075 9000 or csirnet@nta.ac.in, the contacts given in the December 2026 FAQs.

Three worked cases, calculated by us for the December 2026 cycle:

• Woman, General category, born 3 March 1993. She is 33 on the reference date. Her ceiling is 35, so she is inside the JRF limit.
• Man, General category, born 10 June 1995. He is 31, above the ceiling of 30, so he is out for JRF. With two years of certified research his ceiling becomes 32, and he is inside.
• Woman who is also SC, born 1 January 1990. She is 36. Relaxation is capped at 5 years in total, not 10, so the ceiling is 35 and she is out for JRF. She can still qualify for Assistant Professor or PhD admission.

That last route matters: the bulletin sets no upper age limit for Assistant Professor or for PhD admission only.

Qualifying places you in one of three categories, and your degree and age decide which are open to you. Clause 1.7 of the bulletin sets them out.

The number of candidates in each category is decided by a results committee, and the number of fellowships per subject is limited and can change between cycles. Our CSIR NET Maths cut-off guide covers the marks involved.

Categories 2 and 3 can replace a university's own PhD entrance test. Their marks are valid for one year, and admission weighs 70% on the NET score and 30% on the interview. The Assistant Professor certificate has no end date. As of the December 2026 bulletin, a JRF registered for a PhD can be upgraded after two years to Senior Research Fellow (SRF) at ₹42,000 a month, if an expert committee approves their research progress (clause 1.8).

If your aim is a PhD at an Indian Institute of Technology (IIT), the other common route is the Graduate Aptitude Test in Engineering (GATE). Our guide to GATE Mathematics vs CSIR-NET for IIT PhD compares the two.

As of the December 2026 bulletin, the fee is ₹1,150 for General candidates, ₹600 for General-EWS and OBC-NCL, and ₹325 for SC, ST, PwD/PwBD and Third gender candidates. A late application adds ₹500. The fee table is in the bulletin.

The paper is a 180-minute computer-based test, bilingual in Hindi and English. Mathematical Sciences has 120 questions in three parts, but you answer at most 60. The marking scheme in clause 3.2 is:

The total is 15 × 2 + 25 × 3 + 20 × 4.75 = 30 + 75 + 95 = 200 marks. Part C questions can have more than one correct option, and credit needs every correct option. Only your first 15, 25 and 20 answers in each part are evaluated. Our CSIR NET Mathematical Sciences syllabus guide lays out what Parts B and C cover.

We teach CSIR NET Mathematics as live online classes with recordings, in Hindi and English. Our batches add weekly doubt sessions, mock tests with performance analysis, previous year questions with detailed solutions and handwritten class notes. They suit MSc students and beginners starting from scratch.

As of October 2026, our CSIR-NET Dec 2026 Live Batch costs ₹11,999 (or 3 instalments of ₹3,999.67). It began on 10 July 2026 and runs until January 2027. If you are not ready for December, our CSIR-NET and GATE Mathematics live batch for 2027 costs ₹15,999 (or 4 instalments of ₹3,999.75) as of October 2026.

You can also try our teaching first with free lectures, demo classes and a PDF drive.
