Psychometric analysis of forensic examiner behavior
Forensic science often involves the comparison of crime-scene evidence to a known-source sample to determine if the evidence and the reference sample came from the same source. Even as forensic
Implementing blind proficiency testing in forensic laboratories: Motivation, obstacles, and recommendations
Regular proficiency testing of forensic examiners is required at accredited laboratories and widely accepted as an important component of a functioning quality assurance program. Yet, unlike in other testing industries,
Implementation of a Blind Quality Control Program in a Forensic Laboratory
A blind quality control (QC) program was successfully developed and implemented in the Toxicology, Seized Drugs, Firearms, Latent Prints (Processing and Comparison), Forensic Biology, and Multimedia (Digital and Audio/Video) sections
CSAFE 2020 All Hands Meeting
The 2020 All Hands Meeting was held May 12 and 13, 2020 and served as the closing to the last 5 years of CSAFE research and focused on kicking off
How do latent print examiners perceive proficiency testing? An analysis of examiner perceptions, performance, and print quality
Proficiency testing has the potential to serve several important purposes for crime laboratories and forensic science disciplines. Scholars and other stakeholders, however, have criticized standard proficiency testing procedures since their
Crime Lab Proficiency Testing and Quality Management
In the wake of recent reports documenting the vulnerability of forensic science methodologies to human error (e.g., NAS, 2009; PCAST, 2016), the field has sometimes pointed to proficiency testing as
Processing Stamp Bags for Latent Prints: Impacts of Rubric Selection and Gray-Scaling on Experimental Results
We report data on two open issues in our previous experimentation seeking an effective method for development of latent prints on glassine drug bags: (1) the choice of rubric to
Latent Print Proficiency Testing: An Examination of Test Respondents, Test-Taking Procedures, and Test Characteristics.
Proficiency testing is a key component of quality assurance programs within crime laboratories and can help improve laboratory practices. However, current proficiency testing procedures contain significant limitations and can be
Accounting for individual differences among decision-makers with applications to the evaluation of forensic evidence
Forensic science often involves the comparison of crime-scene evidence to a known-source sample to determine if the evidence arose from the same source as the reference sample. Common examples include
Pattern Evidence Research in CSAFE-An Update
CSAFE is a NIST Center of Excellence in Forensic Science. A large portion of CSAFE’s research portfolio is on what is known as pattern evidence, which encompasses any evidence that
