The National Resource Center

National Resource Center

The National Resource Center on ADHD (NRC), a program of CHADD, was established to be the national clearinghouse for the latest evidence-based information on ADHD.  It is primarily funded through a cooperative agreement with the Centers for Disease Control and Prevention (CDC) National Center on Birth Defects and Developmental Disabilities (NCBDDD). The NRC serves as a National Public Health Practice and Resource Center (NPHPRC) with the mission to provide information, education and consultation about assessment, diagnosis, treatment, and issues of health and well-being for children with ADHD and their families.

The National Resource Center on ADHD follows the Healthy People 2020 national objectives to improve the health of all Americans by encouraging collaborations across sectors, guiding people toward making informed health decisions and measuring the impact of prevention activities. The Center works to achieve the following outcomes:

  • To Improve the health and well-being of children with ADHD

  • To Improve the life management skills, adoption of healthy behaviors, and appropriate health choices among people who have been affected by ADHD

  • To strengthen the capacity among healthcare professionals to appropriately diagnose and provide evidence-based treatments for ADHD and co-occurring mental, emotional and behavioral conditions associated with ADHD

  • To strengthen the capacity among education professionals to implement strategies that facilitate learning and academic success among children with ADHD

  • To increase acceptance and reduce stigma associated with ADHD among the general public


As a program of CHADD, the National Resource Center on ADHD works closely with CHADD’s Professional Advisory Board of nationally recognized ADHD experts to ensure that its materials meet the highest standards for scientifically based information.

The NRC does not provide counseling, medical or legal advice or give direct referrals to specific professionals who specialize in the diagnosis or treatment of ADHD, such as psychiatrists, pediatricians, psychologists and clinical social workers. The Center does provide numerous resources and information on these professionals and ways to make informed decisions about selecting providers.

The Center is located in the CHADD national office in Lanham, Maryland, just outside Washington, D.C. and is open Monday through Friday 9:00 a.m. to 5:00 p.m. The National Resource Center welcomes visitors (by appointment only) to use its ADHD library of books, reports and peer-reviewed journals.
