Selection Process and Examination Scheme

The Assistant Director selection process comprises written screening and interview evaluation:

Paper-II contains 100 questions (100 marks) testing specialized forensic science disciplines (Ballistics, Biology, Chemistry, DNA Fingerprinting, Documents, Physics, and Toxicology). Examination duration is 2.5 hours with a 0.33 mark (1/3rd) negative marking deduction for each incorrect response.
• Proportionate Marks Adjustment Formula: When questions are deleted by the subject expert committee, RPSC redistributes the weightage across the remaining valid questions using the statutory formula: Effective Score = [Raw Correct Score x (150 / Total Valid Questions)].
• Interview Evaluation (20 Marks): Candidates securing above the qualifying cutoffs in the written screening test appear before the RPSC board for the personality assessment, testing laboratory management and expert witness testimony skills.

Syllabus Breakdown and Technical Evaluation Domains

The forensic disciplines evaluated in Paper-II involve deep domain competencies:

• Ballistics Division: Internal, external, and terminal ballistics, gunshot residue (GSR) analysis via SEM-EDX, and firearm mechanism identification.
