- Animal Care and Use Program Accreditation-Multiple Sites
DEPT OF DEFENSENAICS 541990Due Aug 25, 2026
• The USAMDRD is seeking a sole source to provide international laboratory animal care accreditation membership services and on-site assessments for multiple U.S. Army Medical Research and Development Command animal research facilities. • The NAICS code for this procurement is 1199, which includes Professional, Scientific, and Technical Services; however, this contract does not appear to be for NAICS-compliant services as described by the NAICS code in the description of the requirement, but rather it looks similar to a training or certification service. • Since it appears the requirements are closely aligned with standard professional certifications, such as CLEP (College Level Examination Program) or CPCU (Certified Professional in Computer Unified Threat Defense), this contract may be more related to a fee-based licensing or certification rather than compliance services.
