What is the difference among CSIR, JRF, NET, and UGC NET?

To understand the difference; we need to know these terms one by one. All these examinations are directed towards research oriented professions. UGC and CSIR both are statutory organisations. The description are as follows:

National Eligibility Test (NET)

• This is a requisite examination for individuals aspiring to teach in universities or colleges. 
• It prominently has two categories; assistant professor and junior research fellowship (JRF). 
• It is conducted in 81 subjects and is acceptable all across the country.

Junior Research Fellowship

University Grants Commission conducts NET exam and it tries to present two group of qualifiers which are as follows:

• NET AP – Assistant professor qualified is eligible to apply for lecturership profiles in universities.
• NET AP & JRF- Candidates clearing the JRF cut-off precisely are financed by UGC to carry research/ PhD in their fields of interest. A specified monetary amount is paid to every candidate.

Council Of Scientific and Industrial Research (CSIR)

This is a premiere research institute in India conducting eligibility tests & fellowship for science and science related subjects. The subjects included are :

• Chemical Sciences
• Life Sciences
• Mathematical Sciences
• Physical Sciences

The recent addition to this framework is in the form of the National Testing Agency (NTA). It is a government body established to look up to the administrative forefront of how these exams are to be conducted. 

Both CSIR & UGC have now transferred their entire exam process to NTA to make it more efficient & productive.
