The National Emergency Management Association is?

The National Emergency Management Association (NEMA) serves primarily as a professional organization that represents state-level emergency management directors across the United States. This "umbrella" association facilitates communication, collaboration, and advocacy among its members, allowing for the sharing of best practices and resources related to emergency management.

Its focus is on the support and professional development of emergency management professionals rather than on enforcing oversight or creating federal mandates related to homeland security. Thus, the choice that correctly identifies NEMA highlights its role in bringing together state-level directors to enhance emergency preparedness and response on a state-by-state basis, making it an essential component of national preparedness initiatives.
