CSIR NET 2025 Exam Pattern & Syllabus

The Council of Scientific and Industrial Research – National Eligibility Test (CSIR NET) is conducted by NTA for eligibility of Indian nationals for Junior Research Fellowship (JRF) and Lectureship/Assistant Professor in the fields of science and technology. It is held twice a year and covers five core subjects: Chemical Sciences, Earth Sciences, Life Sciences, Mathematical Sciences, and Physical Sciences. This article provides the latest CSIR NET 2025 exam pattern, subject-wise syllabus breakdown, marking scheme, and all official links for your preparation strategy.

🔍 CSIR NET 2025 Selection Process

The selection process for CSIR NET 2025 consists of:

1. Online Computer-Based Test (CBT)
2. Declaration of Result (JRF or Lectureship Eligibility)
3. Document Verification by Institutes (during admission or recruitment)

There is no interview in CSIR NET. Your score determines eligibility, not selection into institutions.
