## SDO Updates

## Published

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.
                  - ANSI/ASB Best Practice Recommendation 089, *Best Practice Recommendation for Facial Approximation in Forensic Anthropology*, First Edition, 2020 . This document, initially developed by OSAC’s Anthropology Subcommittee and finalized by the ASB Anthropology Consensus Body, provides guidance for facial approximation from skeletal remains. The production and assessment of facial approximations using skeletal remains represents a combination of varied methods of art and anatomical science that continue to evolve. Therefore, recommendations for specific techniques are not addressed. Facial imaging procedures such as composite drawings and postmortem imaging from photographs are not addressed.

## Work Proposals for New or Revised Standards

The following documents are being initiated and are expected to result in a new or revised standard.

### ASB:

                  - 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.

## 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.”
