The National Institute of Justice published Addendum 3 to NIJ Standard 0101.07, Ballistic Resistance of Body Armor, on November 25, 2025. The document does not stand alone. According to NIJ, Addendum 3 provides specific revisions to the core text of Standard 0101.07 and also updates provisions established in Addendum 1 and Addendum 2 of the same standard. All three addenda layer onto the base document, which replaced the previous NIJ Standard 0101.06 — a standard that had been in effect since 2008.
Among the specific improvements included in the updated standard are revisions to test methods for armor designed for female officers. That is a concrete methodological change with direct implications for manufacturers and testing laboratories. The standard already incorporated a suite of standardized test methods and laboratory practices developed by ASTM International, and the addendum continues within that framework.
The Standard's Role in Certification
NIJ Standard 0101.07 serves as the primary performance requirement document for ballistic-resistant body armor used by U.S. law enforcement, according to NIJ. It specifies minimum performance requirements and test methods for armor intended to protect the torso against handgun and rifle ammunition. The standard introduced the RF2 intermediate threat level to address evolving ballistic threats — a classification that sits between legacy protection levels and fills a gap identified through law enforcement input.
A companion document, NIJ Standard 0123.00, Specification for NIJ Ballistic Protection Levels and Associated Threats, works alongside 0101.07. Standard 0123.00 defines the specific ballistic threats identified by U.S. law enforcement as representative of current prevalent threats. Together, the two documents form the technical foundation for the NIJ body armor program.
That program has three core components: performance standards, compliance testing, and the maintenance of a compliant product list, according to NIJ. The NIJ Compliance Testing Program, known as the CTP, uses these standards to test, evaluate, and certify commercially available body armor. NIJ-approved ballistic testing laboratories conduct the actual compliance evaluations.
How Manufacturers Enter the Process
Participation in the NIJ Compliance Testing Program is voluntary for manufacturers. Those who want their products listed must submit them to the CTP themselves. Manufacturers bear responsibility for that submission. Products that pass appear on the NIJ Compliant Products List.
Not all submitted products pass. Approximately 37 percent of body armor models submitted for testing have historically failed to meet NIJ standards, according to NIJ data. That figure matters when agencies use the Compliant Products List as a procurement filter — only tested, listed models have cleared that threshold.
With the publication of Addendum 3, the NIJ CTP manages an orderly transition process for testing new models against the updated 0101.07 requirements. The transition process is an established part of how the program handles standard revisions, ensuring that the pipeline of products moving through testing reflects current specifications rather than superseded ones.
Scope of the NIJ Body Armor Program
The body armor standards program extends beyond ballistic threats. NIJ also maintains separate standards for stab-resistant body armor, which protects against slashes and stabs from knives and spikes. Those standards operate independently of 0101.07 and 0123.00 but fall within the same program structure.
The November 25, 2025, publication of Addendum 3 is the latest revision in a standards line that has been updated incrementally since 0101.07 first replaced 0101.06. Each addendum carries formal standing — agencies, procurement offices, and testing laboratories treat addenda as binding updates to the parent standard, not as informal guidance. For law enforcement agencies actively sourcing ballistic-resistant body armor, the operative question is whether the products under consideration have been tested and listed under the version of the standard that includes all current addenda.
