• Design and implementation of a proficiency test for fingerprint quality assessors
• Participants completed the test using a grading system to assess fingermark quality.
• No participant was deemed ‘proficient in fingermark grading’.
• Training needs for future proficiency tests have been identified.
• Proficiency in grading may aid future collaborative practise.
Significant numbers of institutions are carrying out fingermark based research, yet there appears to be little inter-institution consistency in the approaches used to assess the quality of the samples produced. Inter-institution consistency in quality assessment would lead to inevitable benefits in collaborating research projects, given that data from multiple projects may be combined, or compared. In order for such quality assessment schemes to be effectively used across multiple institutions, proficiency in using such approaches should be identified to ensure parity. Intra-institution controls on fingermark quality assessment are likely to help manage variations between researchers from the same institution and/or project(s). Proficiency testing (PT) is a popular means of comparing and monitoring the competency of individuals, whilst also assessing the validity of data and conclusions. This project aimed to develop a proficiency testing scheme for the assessment of fingermark quality for researchers. A grading system was developed to assess the quality of fingermarks generated within research projects. A large collection of test fingermark samples was created controlling variables such as force, fingermark composition and surface type. An ‘inter-laboratory testing scheme’ design was used for the proficiency test and established fingermark researchers participated in the project to produce known values for 6 chosen test samples for round one of the testing scheme, described in this paper. Second year BSc (Hons) Forensic Science and Forensic Investigation student participants from the host institution completed the proficiency test as part of a fingermark practical. Results indicated that student participants involved in this project were not able to demonstrate a satisfactory level of proficiency of fingermark quality assessment using this grading system, which was attributed to their relative experience in assessing the quality of fingermarks compared to ‘experts’ in fingermark analysis. Results have highlighted considerations for future grading systems, and additional training requirements of users.
