Advanced ACE-V Applications
Statistics Applied to ACE-V
Exclusionology: Standards and Reducing Errors
Reducing Erroneous Exclusions – Workshop
Current Research Supporting ACE-V
Demystifying Error Rates in Forensic Science
Basic ACE-V Principles

 

Advanced ACE-V Applications
Instructor: Glenn Langenburg
Length: 40 hours, 5 days
Provided through Ron Smith and Associates
Synopsis:
Advanced ACE-V Applications (AAA) for Fingerprint Examiners is a medium to advanced level fingerprint course. In the course, we deconstruct the ACE-V process to understand the stages of ACE-V, its history and philosophy, decision-making processes, and quality assurance mechanisms. We review the current research which explores and supports ACE-V. We also explore other difficult topics such as error rates, distortion mechanism, complex cases, documentation, accreditation issues and preparation, and testimony post-Daubert and post-NAS report.

Statistics Applied to ACE-V
Instructors: Cedric Neumann and Glenn Langenburg
Length: 40 hours, 5 days
Provided through Two N’s Forensic LLC
Synopsis:
Statistics Applied to ACE-V is an advanced level fingerprint course. In the course, we explore basic probability theory and statistics. We apply this theory to forensic concepts and explore such topics as Bayes theorem, likelihood ratios, error rates, and statistical models. We explore the use of traditional ACE-V approaches and how to incorporate a statistical model into the framework of ACE-V. We also look at the history and use of probabilities in the courtroom and common pitfalls and issues. Note: students will NOT have to do a lot of mathematics. As instructors, we focus much more on the principles and applications and not complex mathematics and equations. This is a fun and challenging fingerprint course—not a mathematics course!

Exclusionology: Standards and Reducing Errors
Contact Eric Ray at eric@rayforensics.com
Instructors: Eric Ray and Penny Dechant
Length: 24 hours, 3 days
Provided through: Ray Forensics
Synopsis:
Exclusionology: Standards and Reducing Errors is an intermediate to advanced level course designed to increase latent print examiner’s understanding and confidence in the exclusion decision. The ACE process has striking differences when used to reach an Exclusion decision as opposed to reaching an Identification decision. This course examines the Analysis, Comparison, Evaluation, and Verification stages and how they relate to the Exclusion decision. The appropriate use of the Inconclusive decision is also discussed. The course offers practical comparison exercises as well as examples of erroneous exclusions from casework. Students will discuss options for an exclusion standard and learn to approach exclusions in a new way to avoid the most common error in latent fingerprint comparison.

Reducing Erroneous Exclusions – Conference Workshop
Contact Eric Ray at eric@rayforensics.com
Instructors: Eric Ray and Penny Dechant
Length: 4 hours or 8 hours
Provided through: Arizona Department of Public Safety
Synopsis:
Exclusion decisions are a fairly recent development in latent print comparisons, and the discipline is still struggling with how to handle them. Erroneous exclusions are being discovered with surprising frequency in latent print units around the country. Many labs have begun to verify their exclusion decisions which has finally revealed these errors. Recent research into the decisions of latent print examiners shows that erroneous exclusions are common and inevitable. So, what training have you had in exclusions? What is enough for an exclusion? What is your lab’s standard for exclusion? Is your lab implementing any new Quality Assurance policies to address this problem? This workshop will review the policy changes that Arizona DPS has implemented in their latent print unit to reduce erroneous exclusions. Examples of erroneous exclusions from casework will be presented along with information on circumstances that might make an erroneous exclusion more likely. Hands-on comparison exercises will demonstrate a practical approach to exclusion decisions.

Current Research Supporting ACE-V
Contact Glenn Langenburg at glenn@eliteforensicservices.com
Instructor: Glenn Langenburg
Length: 8-16 hours, 1-2 days
Provided through: Elite Forensic Services
Synopsis:
This workshop explores the research, papers, and studies that report on the ACE-V process. This workshop is especially useful for preparing for admissibility hearings (Frye, Daubert, Rule 702, etc.) because we review all of the relevant research that applies to ACE-V and friction ridge examination.

Demystifying Error Rates in Forensic Science
Contact Glenn Langenburg at glenn@eliteforensicservices.com
Instructor: Glenn Langenburg, Cedric Neumann, or Carey Hall
Length: 8 hours, 1 day
Provided through: Elite Forensic Services
Synopsis:
This workshop explores the theory and foundation of error rates. We explore the concepts of false positives, false negatives, error rates, discovery rates, sensitivity, and specificity. Students will learn how to calculate and apply error rates using actual data from published error rates studies in forensic science. This workshop is applicable to any forensic discipline where categorical decisions or assignments (qualitative or quantitative apply) are made.

Basic ACE-V Principles
Contact Glenn Langenburg at glenn@eliteforensicservices.com
Instructor: Glenn Langenburg, Eric Ray, or Carey Hall
Length: 40 hours, 5 days
Provided through: Elite Forensic Services
Synopsis:
This basic introductory course is a mix of comparison (searching) exercises and basic fingerprint topics. We explore the basics of ACE-V, ridgeology, some high profile, notable fingerprint cases, fingerprint history, and Daubert. Between lectures we will learn how to be efficient in comparisons and perform hundreds of latent print comparisons. This is a great introductory course for examiners who are relatively new and looking for a well-rounded course in broad fingerprint topics and comparisons. NOTE: Students MUST bring hand-held magnifiers to class.
