Society Of Toxicology

Society Of Toxicology, a tax-exempt non-profit professional organization based in Reston, Virginia, serves federal agencies as a prime recipient of federal grants and a prime contractor for conference registration and toxicology education services, with no subcontract footprint and no set-aside designations across its federal award portfolio.

SOT represents over eight thousand toxicology scientists globally and delivers concrete services centered on annual conference hosting, scientific workforce development, and specialized training. On the contract side, SOT provides registration services and conference logistics to federal agencies attending its annual meetings. Recent purchase orders from the EPA Office of Research and Development total roughly $65 thousand across multiple fiscal years (Feb 2022 through Jan 2025) for registration fees at SOT's annual meetings in San Diego, Nashville, Salt Lake City, and Orlando, with individual purchase orders ranging from $10,925 to $13,015. SOT also holds a $52,681 firm fixed-price purchase order from the Food and Drug Administration (awarded Dec 2023, completion Oct 2026) to conduct up to four half-day workshops on emerging toxicological science challenges in food and ingredient safety, performed in Berwyn Heights, Maryland.

On the federal grant side, SOT acts as prime recipient on education and workforce-development grants from the National Institute of Environmental Health Sciences (NIEHS). A project grant awarded May 1, 2026 (completion Apr 2028) funds SOT's Undergraduate Development Program — travel support and mentoring for 35 participants (30 undergraduate students and 5 faculty advisors) over two annual meetings in San Antonio (2027) and Nashville (2028), with curriculum focused on career pathways in biomedical and environmental health sciences. A prior NIEHS project grant (Feb 2024, completion Mar 2025) supported SOT's Undergraduate Diversity Program targeting underrepresented groups in science. SOT also serves as a sub-recipient on the UC Davis-led IPERT grant (Sep 2025 forward), where SOT provides student recruitment assistance, mentor identification, curriculum quality review, and coordination with SOT diversity and education committees.

Customer concentration is diffuse across federal research agencies. The EPA Office of Research and Development leads by award count (13 awards, $161 thousand), while the FDA leads by potential value (5 awards, $345 thousand). The National Institutes of Health and NIEHS together account for 17 awards, with smaller engagement from NIH parent and EPA subsidiary offices. Recent award activity has been modest — four awards in 2024, two in 2025, one in 2026 — and only one award faces ultimate completion within the next twenty-four months, carrying minimal recompete exposure. The combined potential value across all forty-six awards (prime and sub) is $568 thousand, though obligated dollars total $1.7 million, reflecting multi-year grant commitments and the federal government's historical funding of SOT's education and conference programming since at least 1990.
