Selection Criteria of DRDO RAC Scientist `B’ & Scientist/ Engineer ‘B’ Posts:

  1. For Subjects/Disciplines under Part-I : The final selection of the candidates will be purely on the basis of discipline wise category wise merit of aggregate of 80% weightage of marks in the Written Examination and 20% weightage of marks in Personal Interview.
  2. For Subjects/Disciplines under Part-II: The final selection of the candidates will be purely on the basis of discipline wise category wise merit of aggregate of 80% weightage of GATE score and 20% weightage of marks in Personal Interview.
  3. The final selection of PwD (HH), PwD (LD), PwD (AAV/Dw) candidates against the vacancies reserved for them in the applicable disciplines will be purely on the basis of combined merit of aggregate of 80% weightage of GATE score and 20% weightage of marks in Personal Interview.
  4. Only those candidates securing minimum qualifying marks of 70% (for UR category) and 60% (for EWS/OBC/SC/ST/PwD category) in the Personal Interview will be considered for preparation of final merit list. Candidates who do not qualify the interview will not be considered for final selection irrespective of their Written Examination score (for Part-I disciplines) / GATE score (for Part-II disciplines).
  5. The selection against the UR vacancies will be done first based on the combined merit list of all candidates. The filling up of backlog vacancies in OBC/ SC/ ST category will be taken up after exhausting the UR vacancies.
  6. In the merit list for final selection, candidates will be considered for selection against the vacancies in the organizations (DRDO/ DST/ ADA) they opted for, in order of their preference. They will be accommodated against the vacancies of that organization where their selection is definite and will not be kept in any waitlist of their higher preferences.
  7. In addition to the above, any other selection tool/test may be administered, at the sole discretion of RAC.
