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.

OSAC's Geological Materials Subcommittee "Digging In" to Standards
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.
OSAC Adds Two New Standards to the Registry in FY 2019 Q4
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:
ANSI/ASB Best Practice Recommendation 010, Forensic Anthropology in Disaster Victim Identification: Best Practice Recommendations for the Medicolegal Authority, First Edition, 2018. This document, also made effective September 5, 2019 and developed by OSAC’s DVI Subcommittee, provides guidelines and best practices relevant to the role of forensic anthropology in a DVI operation. Anthropological methods, techniques and principles are typically employed in five primary capacities: 1) during the Preparedness phase of a DVI operation, 2) the Search and Recovery and preservation of remains from a mass fatality incident, 3) at the Triage Station during the initial sorting of material gathered from the field and determination of what human tissue enters the morgue, 4) at the Anthropology Station collecting quality postmortem data from each morgue sample, and 5) as a member of the ID Reconciliation Team, focused on ensuring valid and reliable positive identifications from human tissues. Focus in this document is primarily on the Triage and Anthropology Stations.
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.

2019 OSAC All-Hands Meetings a Success
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.
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.

2019 OLSS Meeting Highlights
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 2.0 Announced: The OSAC 2.0 transition was presented by NIST, and attendees provided feedback on ways to enhance the transition. The purpose of OSAC 2.0 is to streamline the development of standards and reduce the overall costs associated with OSAC’s large meetings. Streamlining the processes allows interim standards to be developed more quickly without compromising technical rigor. Meeting cost reductions will allow OSAC to support other high priority activities such as process mapping, interlaboratory studies, interdisciplinary activities, and additional support for high performing subcommittees.
OSAC 2.0 Near Term: Some of the OSAC 2.0 activities will occur in the near term, such as transitioning Resource Committee (RC) members to voting members of subcommittees and revamping the RCs as Task Groups. Embedding RC members in subcommittees ensures that diverse perspectives are included during the initial drafting of documents when legal, human factors, and quality issues can e easily inserted, as opposed to editing after the document is completed. Keeping RC task groups will allow these stakeholders to continue to have a venue to discuss pressing issues informally with their peers.
OSAC 2.0 Longer Term: Other OSAC 2.0 activities, which will be scheduled to start on October 1, 2020, include a potential change in the number of OSAC SACs and subcommittees and transitioning SACs to voting members of subcommittees, interdisciplinary task groups, or new Technical Review Panels (TRPs). These new TRPs will be set up to perform a review on test methods, practice documents, and conclusion scales as they are completed by the subcommittees. This step will eliminate several process steps that were previously required in OSAC 1.0.
Google Suite: OSAC will transition from Higher Logic to the Google Suite of applications for its online document sharing and communication platform. The full transition will be completed by December 15, 2019.
Digital Presence Growing: OSAC’s digital presence is growing with an increase in website views, downloads, and LinkedIn followers, enabling OSAC to reach more stakeholders. As our footprint grows, so does out ability to educate the forensic science community about new standards being developed and championed by OSAC.

OSAC Registry Implementation Corner
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.
Six laboratories have now elected to implement the standards on the OSAC Registry. One of those organizations, the Houston Forensic Science Center (HFSC) has adopted guidelines recommended by OSAC in its continuous effort to improve forensic science results for Houston and impact the broader forensic science community. According to HFSC CEO and President, Dr. Peter Stout, “If we don’t implement what we have talked about for years, it not only doesn’t progress forensic sciences, I would argue it is a step back to ignore the work that has been done.” Read more from Dr. Stout and learn the benefits of being an early implementer of the OSAC Registry approved standards.
If you are an early implementer of the OSAC Registry Approved Standards, we want to hear from you!
In addition to delivering quarterly updates, the fall edition of the OSAC Newsletter also serves as OSAC’s annual report and provides a review of OSAC’s accomplishments and activities over the past fiscal year (FY), October 1, 2018 through September 30, 2019.
Providing technical leadership that facilitates the development of technically sound, science-based standards through a formal standard developing organization (SDO) process.
Evaluating existing standards published by SDOs for placement on the OSAC Registry.
Promoting the use of the OSAC Registry approved standards throughout the forensic science community.
Establishing and maintaining working relationships with similar organizations and other stakeholders.
As of September 30, 2019, OSAC includes:
48 states represented
245 task groups
2600+ applications received
OSAC has made great strides as an organization over the last year. In addition to the successful All-Hands and OLSS Meetings mentioned above, here are a few other examples of our accomplishments from FY 2019:
We have continued investment in developing and reviewing over 200 draft standards across 25 forensic disciplines that will improve the current and future practice of forensic science.
We have made further progress on interdisciplinary projects focused on terminology, training, statistics, and conclusions.
We have supported the development of process maps within the speaker recognition, DNA, firearms and toolmarks, friction ridge, and bloodstain pattern analysis disciplines. Process maps provide better visibility into forensic processes and highlight which parts of these processes are covered by existing standards and which are not.
We have further developed the OSAC Lexicon. Subcommittees are working on updating the Lexicon to make sure all source citations are accurate and complete. The OSAC QIC has developed a new process to ensure terms from published standards are updated in the Lexicon. Consensus has been reached on several new “OSAC preferred” terms and there is now a total of 13 OSAC preferred terms that OSAC members are encouraged to use when drafting standards. In addition, since it was launched in March 2018, OSAC members have been hard at work improving the database of over 4,000 terms. Some features of the Lexicon database redesign include:
The ability to sort/search by subcommittee.
Allowing for more professional output with symbols, subscripts, superscripts used in scientific terms.
Additions of hyperlinked terms and reducing duplicate terms displayed by combining them when in use by more than one subcommittee
Standardization of the citation format for the sources of the definitions.
We have started executing OSAC’s Registry Implementation Plan by conducting brainstorming strategy sessions with each of OSAC’s 25 subcommittees during the July All-Hands Meetings to identify the benefits, challenges, perspectives and needs around implementation. At the end of FY 2019, there were six laboratories on the “tip of the spear” that have elected to implement the standards on the OSAC Registry.
The FSSB serves as the OSAC governing board and supports the organization by overseeing operations of all SACs, SC, and RCs; approving standards for listing on the OSAC Registry; and facilitating communication within and between OSAC and the forensic science community.
In October 2019, the FSSB elected a new Executive Committee and welcomed three new members to the FSSB:
OSAC Executive Committee Members:
Steve Johnson, FSSB Chair, Ideal Innovations and IAI Representative.
Laurel Farrell, FSSB Vice Chair, ANSI National Accreditation Board – Senior Director of Accreditation, and Society of Forensic Toxicologists (SOFT) Representative.

Ongoing Standards Activities
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 email@example.com.
In addition to the annual public update meeting, OSAC participated in other conferences and events throughout the year, including:
American Academy of Forensic Sciences (AAFS) Annual Meeting – February 2019
Texas Forensic Science Commission Meeting – May 2019
American Society of Crime Laboratory Directors (ASCLD) Annual Meeting – May 2019
Association of Firearm and Tool Mark Examiners (AFTE) Annual Meeting – May 2019
American Bar Association (ABA) Annual Prescription for Criminal Justice Forensics Program – May 2019
