About NDAA

NDAA’s mission is to be the voice of America’s prosecutors and to support their efforts to protect the rights and safety of the people.


The National District Attorneys Association (NDAA), located in Arlington, VA, is the oldest and largest national, nonpartisan organization representing state and local prosecutors in the country. Formed in 1950, NDAA has more than 5,100 members across the nation representing state and local prosecutors’ offices from both urban and rural districts, as well as large and small jurisdictions. Our mission is to be the voice of America’s prosecutors and to support their efforts to protect the rights and safety of the people by providing our members with the knowledge, skills, and support they need to ensure justice is attained.

NDAA is recognized as the leading source of national expertise on the prosecution function and is a valuable resource not only for our members, but also for the media, academia, government, and the communities our members serve. Governed by a board of directors made up of appointees chosen by states’ prosecuting associations and current and past NDAA officers, our executive leadership, staff, and board members routinely provide expert policy advice, data, and testimony to the United States Congress and the Executive Branch on a wide variety of criminal justice issues. NDAA also provides amicus curiae briefs to the United States Supreme Court and engages on judicial decisions that impact the work of prosecutors throughout the country to maintain a high standard of ethics and professional responsibility.

NDAA serves as a nationwide, interdisciplinary resource center for research, training, knowledge building, technical assistance, and accountability. To this end, we disseminate books, manuals, newsletters, and monographs on topics and trends in the field ranging from witness protection to crash reconstruction. Our staff conducts or participates in nearly 100 trainings, conferences, and webinars each year. Additionally, the association responds to hundreds of requests for technical assistance each year via telephone, mail, and the website. Our capable staff of junior and senior attorneys along with our training course program directors, aid in furthering the development of expertise in the program areas of gun violence, juvenile justice, DNA/forensics, violence against women, child abuse, capital litigation and human trafficking. The National Traffic Law Center, a division of NDAA, provides expertise on traffic safety issues with a focus on impaired driving and commercial driver’s license violations. We remain committed to serving as the voice of America’s prosecutors and ensuring that justice is achieved for the millions of Americans who rely on our members.
