This exam is held twice a year and is conducted by the National Testing Agency (NTA) on behalf of CSIR.

So, why is CSIR NET such a big deal? It’s simple—it opens doors to careers in academics, research labs, and top-tier institutions like CSIR Labs, IITs, IISc, and more. It is also often considered as a benchmark for quality and academic excellence.

And here’s where Chandu Biology Classes steps in. Known for their dedicated focus on Life Sciences, they have successfully guided thousands of students through the nuances of the exam, starting from eligibility to final preparation.

They believe the first step to success is knowing if you’re eligible. Let’s get into the details.

3. Eligibility Criteria Overview

Before diving into specifics, let’s first look at the broad eligibility requirements to appear for CSIR NET. These criteria are based on:

• Nationality
• Academic qualifications
• Age limits
• Subject specialization

Here’s a quick summary:

Candidates must apply only for the subject they are academically eligible for. For instance, if your post-graduation is in Biology, you can apply for Life Sciences.

If you’re unsure which subject your degree fits into, Chandu Biology Classes recommends checking the CSIR official syllabus and comparing it with your academic curriculum.

This foundational clarity saves you from disqualification due to subject mismatch or degree incompatibility—something many students overlook!

4. Educational Qualifications for CSIR NET

The most crucial factor in determining your eligibility for CSIR NET is your academic background. Here’s what you need to know.

To be eligible, candidates must hold one of the following:

• M.Sc. or equivalent degree with a minimum of 55% marks (General/EWS/OBC) or 50% (SC/ST/PwD)
• Integrated BS-MS
• B.E./B.Tech/B.Pharma/MBBS (for certain subjects)
• Candidates with Bachelor’s degree are only eligible for JRF, not Lectureship, and only under special conditions (like pursuing Integrated MSc-PhD)

Let’s break it down subject-wise:

Life Sciences

• M.Sc. in any Life Science subject like Botany, Zoology, Biotech, Genetics, etc.
• B.Tech/B.E. in Biotechnology (Eligible only for JRF)

Chemical Sciences

• M.Sc. in Chemistry or related sub-disciplines
• B.Tech/B.E. in Chemical Engineering (Eligible for JRF)

Physical Sciences

• M.Sc. in Physics or related disciplines

Mathematical Sciences

• M.Sc. in Mathematics/Applied Mathematics

Earth Sciences

• M.Sc. or equivalent degree in Earth Science/Geology/Oceanography

What Chandu Biology Classes Recommends

They advise students to double-check the degree name on your certificate, match it with CSIR’s subject-wise eligibility list, and never assume interdisciplinary degrees are accepted automatically. This single check has saved many students from application rejection.

5. Age Limit for CSIR NET

Age plays a different role depending on whether you’re applying for JRF or Lectureship.

For Junior Research Fellowship (JRF):

• The maximum age is 28 years as of the 1st day of the month in which the exam is held.
• Relaxation:
  • 5 years for SC/ST/Third Gender/PwD/female applicants
  • 3 years for OBC (Non-Creamy Layer)

So, for example, an OBC candidate can apply up to 31 years.

For Lectureship/Assistant Professor:

• There is no upper age limit.

This flexibility means that even if you’re older than 28 and meet all educational qualifications, you can still become eligible for Lectureship via CSIR NET.

Chandu Biology Classes Insight

They emphasize that students should plan their attempts early for JRF due to the strict age cap, and if you’re nearing the limit, focus all your energy on cracking the next attempt.

They also remind students to keep age proof documents ready, like Aadhar or Class X certificate, for verification.
