CSIR stands for Council of Scientific & Industrial Research. This is a prestigious and premium national organization that is funded by the Ministry of Science and Technology. The aim of CISR is research and development.

The organization conducts a national level with help of the conducting body National Testing Agency (NTA) in the various fields including Physical Sciences, Chemical Sciences, Life Sciences, Mathematical Sciences, and Earth Atmospheric Ocean and Planetary Sciences.

The name of the examination, as many individuals are aware, is called CSIR NET, also referred to as CSIR UGC NET. If any candidate is interested to take the CSIR NET must have certain qualifications. They must have a master’s degree with 55% and above with completion of a course from some UGC recognized institution.

The examination takes place across the nation twice a year- once in June and the other in December. If candidates are able to clear CSIR NET then they qualify to conduct their research or become lecturers in educational institutes.

If you are able to have the required UGC NET score then you can land the opportunity to take admission for JRF or can apply for a lectureship at universities and colleges in India.

Hence, there are two options after clearing the entrance examination- Junior Research Fellowship and Assistant Professorship Jobs.

There exists a tremendous amount of scope after you clear CSIR NET. These two are the most common career choices after clearing the entrance but there are more options to avail.

Exam Pattern of CSIR NET 2022- Life Sciences

The question paper is divided into 3 parts- Part A, B, and C. The three parts have 20, 50 and 75 questions respectively. Candidates taking the test need to answer 15, 35, and 25 questions each from the three parts respectively.

  • Every question comes with four alternative choices.
  • Every question in Part A, B, and C havea weightage of 2, 2 and 4 each
  • Negative marking consists of 25% in total

Eligibility Criteria for CSIR NET

An individual who wants to take the CSIR NET, must be of Indian Nationality.

There is an age limit for the examination. However, it is different for both Lectureship and Junior Research Fellowship.

As of July 2021, the maximum age limit for applying for Junior Research Fellowship (JRF) is 28 years. For the OBC category, there is an age relaxation of 3 years. And for SC/ST and PWD, the relaxation goes up to 5 years.

However, for Lecturership, there is no such imposed age limit.

Educational Qualification

Individuals need to meet certain educational qualifications before they are eligible to take the CSIR NET-

  • The candidate who wants to take the exam must have an Integrated BS-MS/ MSc or equivalent degree/ BS-4 years/ B. Pharma/ B.Tech/ BE/ MBBS degree or B.Sc (Hons) or some other equivalent degree.
  • Candidates who want to sit for the entrance can also be enrolled in the Integrated MS-PhD program and must have an aggregate mark of 55% for General and OBC categories and an aggregate of 50% for SC/ ST/ PwD candidates.
  • Candidates can be eligible for getting a Fellowship after enrolling for a Ph.D. or Integrated Ph.D. program if they have a Bachelor’s Degree beforehand. The validity period of this Fellowship is for 2 years.
  • Candidates who are enrolled in the M.Sc. program or have qualified 10+2+3 years are likely to be eligible to apply under the category of ‘Result Awaited’ (RA).

Important Note: A candidate who has only acquired a Bachelor’s Degree will be eligible for applying only for the Junior Research Fellowship (JRF) but not for the Lectureship (LS).
