Joint CSIR UGC NET is a test being conducted to determine the eligibility of Indian nationals for Junior Research Fellowship (JRF) and for Lectureship (LS) /Assistant Professor in Indian universities and colleges subject to fulfilling the eligibility criteria laid down by UGC. Joint CSIR-UGC NET Fellowship programme is aimed at National Science & Technology Human Resource Development. A large number of JRFs are awarded each year by CSIR to candidates after qualifying the Test conducted by CSIR twice a year in June and December.

Essential Educational Qualifications:
  1. M.Sc. or equivalent degree with at least 55% (without rounding off) marks for General (UR)/General-EWS and OBC candidates and 50% (without rounding off) for SC/ST, Third gender and Persons with Disability (PwD) candidates.
  2. Candidates enrolled for M.Sc. or having completed 10+2+3 years of the above qualifying examination as on the closing date of online submission of Application Form, are also eligible to apply in the above subject under the Result Awaited (RA) category
  3. B.Sc. (Hons.) or equivalent degree holders or students enrolled in Integrated MS-PhD program with at least 55% marks for General (UR)/General-EWS and OBC candidates; 50%^ marks for SC/ST, Third gender, Persons with Disability (PwD) candidates are also eligible to apply.
  4. Candidates with Bachelor’s degree will be eligible for CSIR fellowship only after getting registered/enrolled for Ph.D./Integrated Ph.D. program within the validity period of two years.
  5. Candidates possessing only Bachelor’s degree are eligible to apply only for Junior Research Fellowship (JRF) and not for Lectureship (LS)/Assistant Professor. ^(without rounding off)
  6. The eligibility for Lectureship/Assistant Professor of NET qualified candidates will be subject to fulfilling the criteria laid down by UGC. Ph.D. degree holders who have passed Master’s degree prior to 19th September 1991, with at least 50%^ marks are eligible to apply for Lectureship/Assistant Professor only. ^(without rounding off)
  7. Candidates belonging to the Third gender category are eligible to draw the same relaxation in fee, age and Eligibility Criteria for NET (i.e. JRF and Assistant Professor) as are available to SC/ST categories. The subject-wise qualifying cut-offs for this category would be the lowest among those for SC/ ST/ PwD/ OBC–NCL / General-EWS categories in the corresponding subject.

Upper Age Limit
  1. JRF: Maximum 28 years as on 01/07/2021* {upper age limit may be relaxable up to5 years in case of SC/ST/Third gender/Persons with Disability (PwD)/female applicants and 03 years in case of OBC (Non-Creamy Layer) applicants}.*This age limit is applicable for the current examination cycle only.
  2. Lectureship (LS)/ Assistant Professor: No upper age limit.

Mode of Examination
  1. The Examinations will be conducted in Computer Based Test (CBT) mode
Pattern of Question Paper
The Test will consist of three parts. All the parts will consist of objective type, multiple choice questions. There will be no break between papers. The subject-wise scheme of examination is as per details below:

CHEMICAL SCIENCES PART A PART B PART C TOTAL
Total questions 20 40 60 120
Max No of Questions to attempt 15 35 25 75
Marks for each correct answer 2 2 4 200
Marks for each incorrect answer (Negative marking for part A, B & C is @ 25%) 0.5 0.5 1 -

Chemical Sciences: The candidate is required to answer a maximum of 15, 35 and 25 questions from Part-A, Part-B and Part-C respectively. If more than required number of questions are answered, only first 15, 35 and 25 questions in Part A, Part B and Part C respectively will be taken up for evaluation. Below each question in Part A, Part B and Part C, four alternatives or responses are given. Only one of these alternatives is the "correct" option to the question. The candidate has to find, for each question, the correct or the best answer.

Paper Section Details
  1. Part 'A' shall be common to all subjects. This part shall contain questions pertaining to General Aptitude with emphasis on logical reasoning, graphical analysis, analytical and numerical ability, quantitative comparison, series formation, puzzles etc.
  2. Part 'B' shall contain subject-related conventional Multiple-Choice questions (MCQs), generally covering the topics given in the syllabus.
  3. Part 'C' shall contain higher order questions that may test the candidate's knowledge of scientific concepts and/or application of the scientific concepts. The questions shall be of analytical nature where a candidate is expected to apply scientific knowledge to arrive at the solution to the given scientific problem.
