The National Resource Center on AD/HD (NRC), a program of CHADD, was established to be the national clearinghouse for the latest evidence-based information on AD/HD. 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 AD/HD and their families. This is provided through videos, podcasts, weekly newsletters and an AD/HD Helpline (1-866-200-8098).
