Eric Ray and Glenn Langenburg discuss the recent paper on Blind Proficiency Testing from the Houston Forensic Science Center: "Latent print quality in blind proficiency testing: Using quality metrics to examine laboratory performance" by Brett O. Gardner, Maddisen Neuman, and Sharon Kelley. The paper describes the results of over two years of blind proficiency testing in the latent print unit. No false positive errors were detected over all samples when the examiners were not aware that they were being tested. The paper also describes the use of LQMetric in measuring the Quality of the sample latent prints. A fantastic paper and a great model for other agencies to imitate.
