Interlaboratory studies (ILS) are critically important to standardization efforts, but running them effectively can be a challenge. For example, how many laboratories should participate to obtain statistically significant information? How will participating laboratories be identified and the samples distributed?
The OSAC Seized Drugs Subcommittee is partnering with Collaborative Testing Services (CTS) and ASTM International to execute an ILS program regarding two drug standards currently being revised at ASTM. According to the Seized Drugs Subcommittee Chair, Agnes Winokur, “The goal of the study is to collect and evaluate sufficient data to accurately determine the precision and bias of the test. Precision and bias information in published standards help stakeholders understand what results to expect when operators in different laboratories test the same material with different equipment but following the same standard.”
ASTM International has an ILS program that offers many benefits, including review of the experimental design, assistance in data collection, and statistical processing. Together with CTS, which is assisting with the coordination of sample distribution and data collection, the Seized Drugs subcommittee hopes to conduct its first interlaboratory study in 2020.

The 104th International Association for Identification (IAI) Educational Conference was held August 11-17 in Reno, NV. The IAI Conference provided an extraordinary opportunity for OSAC to educate the community about the forensic science standards that are currently available, or being developed, and to invite them to participate in the standards development process. Eight OSAC members were there to share information about OSAC and provide updates on the latest activities of their subcommittees. You can view their presentations and highlights on OSAC’s website and LinkedIn page.

OSAC’s Geological Materials Subcommittee, in collaboration with the University of Kentucky, College of Agriculture, Food and Environment (CAFE) Plant and Agricultural Communications Department, are developing a training video to help educate law enforcement and crime scene professionals on how to collect soils and other geological evidence. This video is intended to accompany OSAC’s Geological Methods Subcommittee draft collection guide which provides details for field personnel responsible for collecting soil and geological material evidence at a crime scene, alibi locations, and/or reference locations.
The training video was shot in September and is currently being edited by the University of Kentucky CAFE Department of Agricultural Communications Staff. Once developed, the video will be made available to the Geological Subcommittee for future use.
The OSAC Registry serves as a trusted repository of high-quality, science-based standards and guidelines for the practice of forensic science. To be placed on the Registry, a standard or guideline must have been developed using a consensus-based process and have passed the OSAC technical merit review by forensic practitioners, academic researchers, statisticians, and measurement scientists. OSAC encourages all relevant agencies and practitioners to implement the standards listed on the OSAC Registry.
In FY 2019 Q4, the OSAC Forensic Science Standards Board (FSSB) approved the addition of the following two standards for listing on the OSAC Registry:
For a complete list of the OSAC Registry Approved Standards and the standards under consideration, please visit the OSAC website.
Forensic science can be a powerful force in support of justice and public safety. Properly applied, it clears the innocent and helps convict the guilty. OSAC is working to strengthen forensic science by facilitating the development and implementation of technically sound standards and guidelines and encouraging their implementation. In recognition of National Forensic Science Week 2019, held September 15-21, OSAC took to LinkedIn and highlighted several standards and guidelines currently on the OSAC Registry or in the Registry approval process that will be beneficial for the forensic science community.
The 2019 OSAC All-Hands Meetings, held at the Rosen Shingle Creek in sunny Orlando, FL achieved its goals of broadening the knowledge of standards across OSAC’s five Scientific Area Committees (SACs) and 25 discipline-specific Subcommittees (SCs) and providing OSAC members the opportunity to come together to work face-to-face to accelerate the development of standards for the forensic science community.
The first week of meetings were held July 9-12 and participants included members of the Chemistry/Instrumental Analysis SAC and subcommittees, the Crime Scene/Death Investigation SAC and subcommittees, and OSAC’s three Resource Committees (RCs).
The second week of meetings were held July 23-26 and included participants from the Biology/DNA SAC and subcommittees, the Digital/Multimedia SAC and subcommittees, and Physics/Pattern Interpretation SAC and subcommittees.
Each week opened with a plenary session, and participants had the opportunity to join in their respective committee meetings, and participate in pitch meetings and open sessions.
The 2020 All-Hands Meetings will be held on March 10-13 and April 21-24 (stay tuned for the location!) and we look forward to bringing OSAC members together again to further advance standards development for the forensic science field.
A special congratulations to the following OSAC members who were recognized at the 2019 All-Hands Meetings for their contributions:

OLSS Members Greg Davis, Mark Keisler, and Chris Plourd engaged at the 2019 OLSS Meeting. |
OSAC hosted its annual OSAC Leadership Strategy Session (OLSS) in Tampa, FL on September 17, 2019. This event brought together the FSSB, OSAC’s governing board, and its 25 subcommittee chairs to discuss progress made and strategies for the coming year. Highlights from this year’s meeting include:
OSAC extends its deepest sympathy to the family, friends, and colleagues of Dr. Robert E. Barsley who passed away on September 28, 2019. Bob was a past chair and member of OSAC’s Odontology Subcommittee since its inception. Bob was a former president and highly honored fellow of the Odontology Section of the American Academy of Forensic Sciences. You can read Bob’s obituary here, provided by Harry McKneeley & Son Funeral Home in Hammond, LA.
OSAC’s mission is to not only facilitate the development of science-based standards and guidelines, but to also encourage the use of those standards throughout the forensic science community. The goal is to have our stakeholders in the forensic science and criminal justice communities embrace the approved standards on the OSAC Registry and implement them into their everyday practice.
In August 2018, the FSSB prepared an OSAC Registry Implementation Plan for our forensic science partners that describes various strategies that OSAC might use to encourage our stakeholders to promote and implement the approved standards listed on the OSAC Registry. There are many potential pathways for implementation and our initial focus is on crime laboratories and other forensic science service providers.
At the July All-Hands Meeting, brainstorming sessions were held with each of OSAC’s 25 subcommittees to identify the benefits, challenges, perspectives, and needs around implementation. A summary of the key findings resulting from the brainstorming sessions and a road map for next steps are available on the OSAC Registry Implementation web page.

The FSSB and OSAC Program Office would like to thank all OSAC volunteers for their time and all the federal, state, and local government agencies, academic institutions, and criminal justice and forensic science organizations that support the OSAC mission by allowing their staff to participate.
OSAC works to identify and promote technically sound, consensus-based, fit-for-purpose documentary standards that are based on sound scientific principles. The OSAC Registry contains a list of approved standards that meet these criteria, as determined by OSAC via a transparent process that allows for participation and comment from all stakeholders.
OSAC is proud to have the following 19 Registry Approved documents effective in FY 2019 (ending September 30, 2019):
Disaster Victim Identification
Facial Identification
Fire & Explosion Investigation
Materials (Trace)
Odontology
Seized Drugs
Toxicology
Interdisciplinary
OSAC fulfills its mission through two distinct efforts, 1.) working with SDOs and 2.) OSAC's Registry Approval process. In the SDO process, OSAC committees or task groups submit an idea, a partially drafted document, or a fully drafted document to an SDO for further development, balloting, and publishing. Once published, selected standards and guidelines may be evaluated further and elevated to the OSAC Registry. The absence of a document from the OSAC Registry does not necessarily mean that OSAC considers it invalid, rather it may mean that the document has not yet been recommended or may only meet some of OSAC’s criteria for inclusion.
The figures below depict the number of standards and guideline projects that reached particular stages in the development process in each of OSAC’s five SACs and 25 SCs.
OSAC is committed to sharing information about standards and activities that will impact the forensic science community. Each year, OSAC reports its activities in an open and online public forum and provides an opportunity for the public to ask questions and provide feedback. This year’s Public Update and Open Discussions Meeting was held on June 5, 2019 at the NIST campus in Gaithersburg, MD. This event featured presentations from the FSSB, the Chairs of OSAC’s five SACs, three RCs, and the Statistics Task Group.
If you were unable to attend this year’s meeting, you can view the recording and presentations on the OSAC website. Also, we encourage you to send any feedback to allison.getz [at] nist.gov (allison[dot]getz[at]nist[dot]gov).
In addition to the annual public update meeting, OSAC participated in other conferences and events throughout the year, including:
OSAC has made great strides to help achieve and develop technically valid and consensus-based standards and guidelines for the forensic sciences. With over 800 combined members and affiliates representing forensic science practitioners, laboratory managers, academic researchers, measurement scientists, and experts in statistics, human factors, legal, and quality infrastructure, we will continue to work together to develop and promote standards that strengthen forensic science.

SOFT's objectives are to:
SOFT provides a forum for the exchange of information and ideas among toxicology professionals in a mentoring, collaborative atmosphere at its annual meeting. SOFT has a long history of supporting laboratory accreditation and personal certification.
SOFT members actively participated in SWGTOX and now over 45 SOFT members are actively supporting the OSAC initiative through service as members at all levels of the OSAC as well as affiliates on Toxicology Subcommittee Task Groups.
SOFT-sponsored programs, including national and regional workshops, newsletters, technical publications, and presentations at the annual meeting are the primary mechanisms to keep the SOFT membership up to date on OSAC activities. These programs and materials also explain how to become involved as an affiliate or member, how to participate by commenting on standards in development, and how to implement standards that have been placed on the OSAC Registry.
