  1. 1. China National Accreditation Service for Conformity Assessment Challenges to develop PT programs in the field of Forensic Science 1 JIA Rujing Proficiency Testing Dept. China National Accreditation Service for Conformity Assessment
  2. 2. 2 CNAS Brief Introduction CNAS is the national accreditation body of China which unitarily responsible for the accreditation of Labs, IBs, RMPs, PTPs and CBs. China National Accreditation Service for Conformity Assessment
  3. 3. 3 CNAS Brief Introduction 6149 407 162 136 59 34 9 1 10 100 1000 10000 Lab IB Medical lab CB Bio-safety Lab PTP RMP CNAS accreditation statistics, by end of 2014
  4. 4. 4 Detection and collection of physical evidence Analysis and interpretation of the evidence Reporting of results and findings About Forensic Science Cant be 100% certain, sometimes inconclusive; Often based on expertise judgment;
  5. 5. 5 2012, APLAC PT Committee set up WG 4 to developing PT in Inspection Forensic Science Forensic PT as show cases: APLAC T087 Cause and Manner of Death (2013) APLAC T096 Printed Document Examination (2014)
  6. 6. 6 Institute: 3600+ (Police) + 5000+ (Others) Case: 4,000,000+/year Forensic Work in China

  10. 10. 10 Challenges and Countermeasures How to Provide Good Cases? How to Evaluate Properly? Acquire and coordinate critical expertise resources Standardization
  11. 11. Through CNAS efforts, Over 100 top Forensic Science experts acquired countrywide including: Medical Doctor, University Professor, Scientist, Researcher, Senior Engineer 11 China Forensic PT expertise resources
  12. 12. Countrywide up-to-date equipment, instrument and facility to support 12 China Forensic PT hardware resources
  13. 13. Performance evaluation group Evaluation criterion set by PT program Committee; Lead by a Committee delegate, 3 or more (odd number) members; Pre-evaluation practice Max 10% scoring variation Approved by Committee delegate Independent evaluation Group decision on argument 13 Performance evaluation of PT
  14. 14. Not able to cover all areas Forensic Psychiatry Not able to evaluate the whole process Upstream vs. Downstream 14 Other Challenges
