Members of OSAC’s Biology/DNA committees and the Scientific Working Group on DNA Analysis Methods (SWGDAM) met in January to continue their work developing a DNA process map for the forensic science community. Expected to be released this summer, this process map will describe the current practice for processing, genotyping, interpreting, and reporting on DNA samples.

Process maps are useful tools that can help provide insight into forensic science methods and processes, identify areas for improvement, and discover where standards may be needed.

Read more about the process maps developed by OSAC’s Friction Ridge and Speaker Recognition Subcommittees. OSAC’s Firearms & Toolmarks Subcommittee is also developing a process map, and the Seized Drugs Subcommittee will be launching a process mapping working session this summer.

OSAC’s Organic Gunshot Residue Task Group (TG) is looking for participants to join an interlaboratory study on the collection and analysis of organic gunshot residues. This study is intended to support a draft standard practice the TG has developed which contains methodologies for gas chromatography/mass spectrometry (GC/MS) and liquid chromatography/mass spectrometry (LC/MS) analyses of organic gunshot residues. 

Visit the Gunshot Residue Subcommittee webpage to learn more about the study and how you can participate.

Help Develop an ASTM Standard on Legal Issues

Help develop a standard on training on legal issues.

Past Chair of OSAC’s Legal Resource Committee, Judge Christopher Plourd, is leading efforts to develop a legal education standard for forensic science practitioners titled Standard Practice for Forensic Science Practitioner and Forensic Science Service Provider Training on Legal Issues.

This proposed standard will identify the recurring and important legal issues that forensic practitioners and forensic science service providers should be aware of and trained on. It will be under the jurisdiction of ASTM Committee E30 on Forensic Sciences and the direct responsibility of Subcommittee E30.11 on Interdisciplinary Forensic Science Standards. 

Judge Plourd has started a work item within ASTM and will be the technical contact for a task group within ASTM. He is looking for approximately 10 forensic science practitioners within OSAC to participate as task group members in the development of this standard. You do not have to be a member of ASTM to be a member of this task group. If you are interested, please email Judge Plourd (christopher.plourd [at] (christopher[dot]plourd[at]imperial[dot]courts[dot]ca[dot]gov)) briefly describing your interest and your background in education and training within your forensic science discipline.

OSAC 2.0 Updates

By OSAC Program Manager John Paul Jones II

OSAC logo

The FSSB, in collaboration with the NIST’s OSAC Program Office, has implemented the following changes in preparation for OSAC 2.0, set to launch on October 1, 2020.

Launched Interim (1.5) Registry Approval Process
This streamlined Registry Approval Process enables subcommittees to advance published standards directly to OSAC’s open comment period. The comment periods are announced in OSAC’s monthly Standards Bulletin and provide an opportunity for OSAC to obtain feedback on whether a standard should be included on the Registry. After the comment period closes and any comments are addressed, a standard is then provided to the FSSB for consideration to place on the OSAC Registry. This interim process was implemented in February 2020 and applies to all OSAC standards submitted to a standards developing organization (SDO) before October 1, 2020.

Implemented “OSAC Proposed Standard” Template
The cover page placed on OSAC’s Tier 3 documents (i.e., those drafted by OSAC and sent to an SDO for formal development) has been updated. This new “OSAC Proposed Standard” template acknowledges the subcommittee that drafted the document, informs the forensic science community and other interested parties that the document is available, and requests their consideration of OSAC’s recommendations relating to applicable forensic science practices. Designated “OSAC Proposed Standards” have been developed with input from experts in a broad array of forensic science disciplines as well as scientific research, measurement science, statistics, law, and policy. Under OSAC 2.0, the “OSAC Proposed Standards” will be eligible for listing on the OSAC Registry.

Updates to OSAC’s Organizational Structure
The FSSB has approved several changes to OSAC’s organizational structure, effective October 1, 2020.  

The updated names for these combined subcommittees will be finalized by early summer.

Transition of Resource Committee Members to Voting Members of Subcommittees
This activity is largely complete with only a few remaining resource committee members needing to make the transition to a subcommittee or stay on the specific resource task group that will continue after the formal resource committees sunset.  The advantages of this restructuring were previously described in the February 2020 OSAC Newsletter.

Development of OSAC 2.0 Technical Review Panel Process
The FSSB’s Technical Review Panel (TRP) Process Task Group has met numerous times during the past two months to develop the criteria for the selection of TRP members and the processes for conducting scientific reviews of technical “OSAC Proposed Standards.” TRP members will be selected from OSAC’s application database, and to ensure a fresh and objective assessment, these panels will be independent of the subcommittee that generated the document they will review. After the process and criteria are developed, OSAC will conduct several pilots to see if changes are needed prior to launch. The criteria and process will be revised to address any challenges identified during the pilots.

FSSB Releases Updated Version of OSAC Organizational Priorities Document

The latest version of OSAC’s Organizational Priorities & Minimum Requirements for Standards Development is now available on the OSAC website. This document outlines the priorities for OSAC to achieve its mission and identifies the minimum topic requirements that SACs and subcommittees need to address when drafting forensic science standards.

Organizational Priorities: History 
In preparation for the January 2015 OSAC Meetings, the FSSB issued guidance that instructed OSAC units to focus their standards development activities on the following priorities:

  • Existing standards that needed updating (e.g., Scientific Working Group (SWG) documents)
  • Terminology
  • Method development
  • Training
  • Method validation
  • Existing standards to be considered for the OSAC Registry
  • Topics that cross disciplines and Scientific Area Committees 
  • Research Needs
  • Cognitive Bias 
  • Reporting

These priorities were first published in December 2014 in OSAC’s Principles of Professional Practice (PPP) and later updated in September 2016. At a September 2017 FSSB meeting, the FSSB determined there was a need to further define what should be included in OSAC drafted standards and to provide further guidance on these priorities.

Based on the outputs from the September 2017 FSSB meeting, the PPP was revised again in December 2017 and renamed OSAC Organizational Priorities. This updated document identified the overarching elements necessary for OSAC to achieve its mission and the priorities of the organization. Following the 2018 OSAC Leadership Strategy Session (OLSS), an FSSB TG was formed to review and revise this document again, this time to identify the minimum topic areas to be covered (regardless of the SDO used) and to coordinate with the FSSB Standardization Roadmap Task Group.

Organizational Priorities: Now
The latest version of the Organizational Priorities document was published in March 2020 and will serve as a helpful guide for OSAC units. The document was renamed Organizational Priorities & Minimum Topic Requirements for Standards Development and allows for a flexible approach to drafting standards. For example, a unit may draft one standard that covers multiple areas, or draft multiple standards for a single area. Regardless of the approach, the document describes the minimum topic requirements that units must address when drafting the following standards: 

  • Competency standards
  • Physical evidence standards
  • Method development standards
  • Method validation standards
  • Reporting results and testimony standards
  • Quality assurance standards

In addition to addressing the required minimum topics described in the document, all SACs and SCs must use OSAC Preferred Terms when drafting standards, as applicable. SAC and SC chairs will be responsible for implementing the requirements outlined in the current organizational priorities document according to the guidelines delineated in the graphic below. The FSSB will continue to review and revise OSAC’s Organizational Priorities document as needed.

Do We Speak the Same Language? Words and Their Meaning are Important to Standards Development

By FSSB Ex Officio Karen Reczek

One of the first steps in standards development is to define terms to ensure everyone is on the same page. For example, the International Organization of Standardization (ISO) requires new Technical Committees to write a terminology standard before starting any work items. Terms are an essential part of all standards. For a standard to be implemented correctly, users need to understand it the same way the writers intended. In order to avoid misunderstanding, definitions should be included for any terms that are included in the requirements. This is particularly important if technical terms requiring specific interpretation are being used.

When OSAC started, an organizational priority from the FSSB was having agreed upon terminology that all OSAC subcommittees will use. This led to the creation of the OSAC Lexicon. With over 4,000 terms related to forensic science, the OSAC Lexicon contains terms from various sources such as existing standards, reference books, Scientific Working Group (SWG) documents, journal articles, and OSAC subcommittees. All the terms and their definitions are sourced, designating the origins of the entry. 

OSAC is continuously striving to improve the Lexicon. For example, we are currently working to obtain consensus on terms, as many have multiple entries and may vary in definition. This is a long-term task, however. An immediate priority is to obtain consensus on specific terms, or “OSAC Preferred Terms.” OSAC Preferred Terms have received input from various levels of the OSAC membership and have been approved by the FSSB. There are currently 16 OSAC Preferred Terms, with more being approved by the FSSB every month. To ensure consistency and to prevent inventing new definitions, OSAC committees are being instructed to use the OSAC Preferred Terms and definitions in their draft standards, as applicable. The FSSB has also directed OSAC committees to use ISO definitions, whenever possible. The FSSB has established an FSSB Terminology TG to review and consider revisions to the current process for obtaining consensus and approving OSAC Preferred Terms. The Terminology TG will also manage the processes for updating and maintaining the OSAC Lexicon.

Want to include a term and help us grow the OSAC Lexicon? Add it using the “Suggest a Term” feature. All suggested terms and their definitions will be reviewed before being added to the Lexicon.

OSAC Registry Implementation Corner

OSAC Registry Banner

The Association of Forensic Quality Assurance Managers (AFQAM) has added an OSAC News section to their website. The first news item AFQAM shared was the joint press release from the Houston Forensic Science Center (HFSC) and OSAC announcing the implementation of standards on the OSAC Registry by the HFSC. OSAC appreciates AFQAM’s support and we encourage you to check their website for future OSAC news. 

Several OSAC members will also be sharing their laboratory’s implementation efforts by publishing news articles in various professional association newsletters. For example, Jeremy Triplett, recently named as the new director of the Kentucky State Police Central Forensic Science Laboratory, will be submitting an article to ASCLD about how one section of his laboratory met the challenges of implementing the OSAC Registry approved standards related to seized drugs. Additionally, Mark Keisler, Indiana State Police Laboratory, Firearms & Toolmarks section chief, also plans to submit an article for the AFTE newsletter about implementing OSAC Registry approved standards within his section of the laboratory. We look forward to reading and promoting these publications soon!

For the forensic science service providers getting ready to undertake standards implementation, here are some helpful tools to guide you:  

These tools are also available on OSAC’s Registry Implementation webpage. Please contact Mark Stolorow at mark.stolorow [at] (mark[dot]stolorow[at]nist[dot]gov) with any questions or for assistance on your implementation journey.

Professional Organization Spotlight

The American Society of Crime Laboratory Directors

Ray Wickenheiser
Ray Wickenheiser, FSSB ASCLD representative

By OSAC FSSB ASCLD representative Ray Wickenheiser

The American Society of Crime Laboratory Directors (ASCLD) is a nonprofit professional society of crime laboratory directors and forensic science managers dedicated to providing excellence in forensic science through leadership and innovation. The purpose of the organization is to foster professional interests; assist the development of laboratory management principles and techniques; acquire, preserve and disseminate forensic based information; maintain and improve communications among crime laboratory directors; and to promote, encourage, and maintain the highest standards of practice in the field.

As the organization representing crime laboratory leadership, ASCLD continues to support the efforts of the OSAC. ASCLD members continue to provide employees from their organizations to participate in the development of standards in OSAC. 

In addition, ASCLD has a Standards and Accreditation Initiatives Committee which focuses on promoting accreditation, standards development, and standards implementation. Through the weekly Crime Lab Minute newsletter, ASCLD notifies its membership of opportunities to review these standards as they are published by an SDO and requests feedback on the impact of any standards recommended for addition to the OSAC Standards Registry. This committee has also made recommendations on standards implementation to the ASCLD Board of Directors and is working on an implementation resource document for the ASCLD Membership.

On February 10, 2020, the ASCLD Forensic Research Committee and Standards & Accreditation Initiatives Committee, with support of the OSAC and International Association for Identification (IAI), distributed a web-based online survey. The survey will promote understanding of the extent to which standards and best practice recommendations developed or approved by OSAC have been or will be implemented or intend to be implemented into agency/organization standard operating procedures. Key challenges and barriers to implementation will be captured as well. This survey provides an important mechanism for identifying potential solutions for lowering implementation barriers and increase the likelihood that agencies/organizations can improve consistency and quality of forensic science practices using OSAC-developed standards.

On March 31, 2020, the survey closed and ASCLD has initiated their review of the data. The survey received 214 participant responses from the joint ASCLD and IAI membership – the vast majority representing U.S. city/county government (59%) and U.S. state government (24%) agencies. The survey captured a variety of perspectives – of the participants that responded, 57% were practicing examiners, 28% were supervisors/managers, and 6% were quality assurance managers.  
Over the next few months, ASCLD will be working to analyze the results and identify potential solutions to support the community with the adoption of standards and best practice recommendations. The ASCLD expects to have a summary available by Fall 2020 and a strategy to assist the community by Winter 2020.
