The CSIR NET exam is one of the most prestigious competitive exams in India, conducted by the National Testing Agency (NTA) on behalf of the Council of Scientific and Industrial Research (CSIR) and the University Grants Commission (UGC). It is held twice a year, typically in June and December, and is designed to assess candidates for Junior Research Fellowship (JRF) and Assistant Professor positions across Indian universities and research institutes.
What is CSIR NET?
The Council of Scientific and Industrial Research National Eligibility Test (CSIR NET) is a national-level examination that determines the eligibility of Indian nationals for JRF and Lectureship/Assistant Professorship positions in Science and Technology fields.
The test evaluates candidates based on their subject-specific knowledge, research aptitude, and general reasoning abilities. The CSIR NET exam pattern is common across all subjects, with three parts – A, B, and C. While Part A is a general aptitude section and common for all candidates, Part B and Part C are subject-specific and assess domain knowledge.
