National Adult Maltreatment Reporting System (NAMRS)

The National Adult Maltreatment Reporting System (NAMRS) is the first comprehensive, national reporting system for adult protective services (APS) programs. It collects quantitative and qualitative data on APS practices and policies, and the outcomes of investigations into the maltreatment of older adults and adults with disabilities.

The absence of data for research and best practice development has been cited by numerous entities, including the Government Accountability Office, as a significant barrier to improving APS programs. Policy makers, APS programs, and researchers will use the data to evaluate and improve programs.

The goal of NAMRS is to provide consistent, accurate national data on the exploitation and abuse of older adults and adults with disabilities, as reported to APS agencies. NAMRS is an annual, voluntary system to collect both summary and de-identified case-level data on APS investigations. NAMRS consists of three components:

  1. Agency Component—submitted by all agencies on their policies and practices. NAMRS Agency Component Data Specifications (PDF, 100KB)

  2. Case Component—data on client characteristics, services, and perpetrator characteristics, provided by agencies that have report-level tracking systems. NAMRS Case Component Data Specifications (PDF, 129KB)

  3. Key Indicators Component—aggregated data on key statistics of investigations and victims, provided by agencies that do not have report-level tracking systems or are unable to provide case-level data. NAMRS Key Indicators Component Data Specifications (PDF, 133KB)

Please see the NAMRS Definitions of Code Values (PDF, 174KB) for a description of the terms used in the three component documents.


On August 29, 2017, ACL released the first of a series or reports based on data from NAMRS. Fifty-four of 56 states and territories contributed data to NAMRS in its first year. This high level of voluntary participation reflects the value that leaders in the field of adult maltreatment see in this data. View the report (PDF, 1.42MB)

Learn about the development and initial pilot on the NAMRS Background page.

Through its National APS Technical Assistance Resource Center, ACL will provide training, assistance, and a mechanism for easily uploading data for participants. Minimal effort will be needed to provide the Agency Component, while the Key Indicators and Case Components will require more effort. The degree of effort will depend on the nature of each program’s case management and data reporting system. Agency IT departments will be a critical partner for most APS programs.

While NAMRS is still in its infancy, the information it will provide in the years to come will directly inform prevention and intervention practices at all levels of the adult maltreatment field.
