P25 compliant, P25 CAP compliant, P25 compliant with the Statement of Requirements (P25 SOR) -- what does it all mean?
P25 CAP, a voluntary program, allows suppliers to publicly attest to their products' compliance through P25 CAP testing at DHS-recognized laboratories. As proof, suppliers are required to submit Summary Test Report (STR) and Supplier’s Declaration of Compliance (SDOC) documents. These documents are available on the Approved (Grant-Eligible) Equipment page. It is this list, and only this list, which is referenced by several federal grant programs, including the Federal Emergency Management Agency, as allowable equipment to be purchased. The varying P25 labels can be confusing, and our guide on P25 terminology explains the program and how the terms apply.

About P25 CAP
The P25 CAP is a partnership of the U.S. Department of Homeland Security’s Science and Technology Directorate, SAFECOM, industry and the emergency response community. The initial program focus is on the Common Air Interface, which allows for over-the-air compatibility between radios and tower equipment. While P25 CAP testing is not currently available for ISSI/CSSI, DHS S&T is working with the Department of Interior to establish an ISSI/CSSI test lab and formalize test procedures to include as part of P25 CAP.
For more information on P25 CAP, watch the video and read the following overview documents listed below:
- The Project 25 Compliance Assessment Program (P25 CAP) establishes standards and compliance test protocols for ensuring the interoperability of the digital communications equipment emergency responders use. The P25 CAP video highlights the P25 CAP Advisory Panel’s efforts to review, evaluate and update the standards to keep pace with advances in digital communications.
- The P25 CAP Compliance: What Should it Mean to You? document provides definitions for common P25 terminology.
- The P25 CAP Fact Sheet describes how the P25 CAP works, the value of the program to public safety, and the program’s long-term-goals.
- The P25 CAP FAQs document addresses commonly asked questions about the program.
P25 CAP activities are supported by Congress.
The Intelligence Reform and Terrorism Prevention Act of 2004 established the Office for Interoperability and Compatibility (OIC) within the S&T Directorate to carry out responsibilities and authorities relating to the SAFECOM Program. The DHS Appropriations Act of 2007 refined and expanded the authorities of OIC within S&T to: support the creation of national voluntary consensus standards for interoperable emergency communications; establish a comprehensive research, development, testing and evaluation program for improving interoperable emergency communications; and encourage more efficient use of existing resources, including equipment, to achieve interoperable emergency communications capabilities.
