Challenges to develop PT programs in the field of Forensic science - Jia Rujing

The 3rd GCC Laboratory Proficiency Conference is organized as part of the strategic orientations of the GCC Standardization Organization (GSO) for the development of the standardization and quality infrastructure, thereby contributing to the development of commerce and industry and to the support of national economy in the GCC member states. Since the field of proficiency testing is newly introduced in the GCC member states and as the infrastructure of laboratories has not yet taken the shape of national or regional organizations representing the laboratories and reflecting their requirements, GSO is in need of meeting with a considerable group of laboratories to explore and prioritize GCC member states’ requirements in terms of the fields which must top the list of the fields to be developed and upgraded. Based on the study conducted by GSO during 2011 on the status of proficiency testing activities in the member states which shown that the laboratories operating in the member states are in need of a unified data center on proficiency testing activities, GSO organized two conferences in 2013 and 2014 on the subject. The conferences scored high rates of success in terms of the selected scientific material, quality of speakers and the targeted audience. Accordingly, GSO conceptualization of the method of coordinating and upgrading the activity of proficiency tests in the GCC member states included a recommendation on the organization of annual training courses and awareness symposia by the GSO on the fields of proficiency tests. This year’s Conference will be held in Dubai during two days the 24th and 25th of March 2015, and will coincide with the annual Analytical Industry exhibition ARABLAB which will be held in Dubai during the period 23 – 26 March 2015.

About Forensic Science
Can’t be 100% certain, sometimes inconclusive;
Often based on expertise judgment;

Challenges and Countermeasures
How to Provide Good Cases?
How to Evaluate Properly?
Acquire and coordinate critical
expertise resources
Standardization
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
• Countrywide up-to-date equipment, instrument
and facility to support
12
China Forensic PT hardware resources
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
• Not able to cover all areas
• Forensic Psychiatry
• Not able to evaluate the whole process
• Upstream vs. Downstream
