== Project 25 Compliance Assessment Program (P25 CAP) ==

The United States [[DHS]]'s Project 25 Compliance Assessment Program (P25 CAP)<ref name=":0">{{Cite web|date=2016-05-22|title=P25 CAP|url=https://www.dhs.gov/science-and-technology/p25-cap|access-date=2020-09-27|website=Department of Homeland Security|language=en}}</ref> aims for interoperability among different vendors by testing to P25 Standards. P25 CAP, a voluntary program, allows suppliers to publicly attest to their products' compliance.<ref name=":0" />

Independent, accredited labs test vendor's P25 radios for compliance to P25 Standards, derived from [[Telecommunications Industry Association|TIA-102]] Standards and following [[TIA-TR8]] testing procedures. Only approved products<ref>{{Cite web|url=https://www.dhs.gov/science-and-technology/approved-grant-eligible-equipment|title=Approved Grant Eligible Equipment|date=February 6, 2017|website=Department of Homeland Security}}</ref> may be purchased using US federal grant dollars.<ref>{{Cite web|date=2017-02-06|title=Approved Grant Eligible Equipment|url=https://www.dhs.gov/science-and-technology/approved-grant-eligible-equipment|access-date=2020-09-27|website=Department of Homeland Security|language=en}}</ref>  Generally, non-approved products should not be trusted to be meet P25 standards for performance, conformance, and interoperability.

P25 product labeling varies. "P25" and "P25 compliant" mean nothing while high standards apply for a vendor to claim a product is "P25 CAP compliant" or "P25 compliant with the Statement of Requirements (P25 SOR)"<ref>{{Cite web|date=2018|title=P25 CAP Compliance: What Should It Mean to You?|url=https://www.dhs.gov/sites/default/files/publications/900_P25-CAP_Construct_What-P25-CAP-Offers_180509_v2-508.pdf|publisher=[[DHS Science and Technology Directorate]]}}</ref>
