The OSAC Registry serves as a repository of scientifically sound forensic science standards that address discipline-specific forensic science needs. OSAC elevates standards to the OSAC Registry as an endorsement of the document’s high quality and to encourage its use by relevant stakeholders in the forensic science community.

The American Academy of Forensic Sciences Standards Board (ASB) has recently published two new documents:
ANSI/ASB Standard 018, Standard for Validation of Probabilistic Genotyping Systems, First Edition, 2020. This standard, initially developed by OSAC’s Biological Data Interpretation & Reporting Subcommittee and finalized by ASB’s DNA Consensus Body, provides an essential framework for forensic laboratories validating a probabilistic genotyping system for the interpretation of autosomal STRs. Forensic laboratories that already use a probabilistic genotyping system can review their validation for compliance with this standard and supplement their previous validation where necessary.
ASB Standard 014, Standard for Friction Ridge Examination Training Program. This document provides the requirements for a forensic service provider’s (FSP’s) training program for friction ridge examiners and includes recommended learning outcomes for the trainee. This document does not provide lesson plans, practical exercises, or performance measures for successful completion of each module. Individual sections only apply to trainees who perform those job functions. Comment deadline August 20, 2020.
Recirculation* – ASB Standard 024, Canine Detection of Humans: Location Check Using Pre-Scented Canines. This document provides the requirements for pre-scented canine location check search using a canine team to search for and identify a specific person’s (target) scent at a given location. This standard promotes consistency across agencies, departments, and organizations utilizing pre-scented canines’ location check search and provide the judicial system optimized protocol. Comment deadline August 24, 2020.
ASB Standard 096, Standard Method for the Examination and Documentation of Ammunition and Ammunition Components. This new standard provides procedures for the examination and documentation of ammunition and/or ammunition components by forensic firearm and toolmark examiners or technicians. Following these procedures, an examiner or technician will be able to document and report the examination of ammunition and/or ammunition components. This document does not cover the microscopic comparison of toolmarks on ammunition components. Comment deadline September 7, 2020.
ASB Standard 135, Anthropology Scene Detection and Processing. This document provides requirements and best practices for forensic anthropology and forensic archaeology practitioners in proper scene detection, processing, handling of evidence, and maintenance of a chain of custody, commensurate with jurisdictional requirements. These requirements and best practices use archaeological techniques and principles as a foundation for scientifically appropriate detection, processing, documentation, and collection of human remains and associated evidence at a scene. Comment deadline September 7, 2020.
*Comments on a re-circulations will only be accepted on revised sections of a document. Comments made to text not revised from the original comment period will not be accepted.
The following documents are being initiated and are expected to result in a new or revised standard.
On July 31, 2020 a Project Initiation Notification System (PINS) was published on page 30 in the ANSI Standards Action. This will begin a 30-day period for public comment on the initiation of ASB’s work on the following documents:
BSR/ASB BPR 143-202x, Best Practice Recommendations for Technical Review in Friction Ridge Examination. This document provides best practice recommendations for conducting technical reviews of friction-ridge impression examinations and general guidance on best practices for technical reviews, including a checklist and sample review forms. This document does not address administrative review or verification.
BSR/ASB Std 145-202x, Standard for Consultation during Friction Ridge Examination. This standard sets documentation, quality, and consultant requirements for consultations during friction-ridge examinations. This document does not apply to conflict resolution.
Three-Part Webinar Series on Biology/DNA Standards and Best Practices
Join OSAC, ASB and Promega for a three-part webinar series that will provide information on new/emerging standards and best practice recommendations for forensic biology and DNA testing laboratories.
Development and Publication of New Standards and Best Practices – The Process (Part 1) – available on-demand
Mixture Interpretation Validation, and Protocol Development and Verification (Part 2) – Wednesday, August 5
Training Standards Overview (Part 3) – Wednesday, September 9
Development of the Term "Exclusionary Difference" and a More Uniform Use of Spectral Comparison Language
Read more from Diana Wright, chair of OSAC’s Materials (Trace) Subcommittee, in the July 2020 issue of the American Society of Trace Evidence Examiners (ASTEE) Newsletter, page 11, regarding a brief history of the evolution of the terms used to describe the differences between items being compared from “significant” to “meaningful” to “exclusionary differences.”
