In the United States a Community Emergency Response Team (CERT) can refer to:
one of five federal programs promoted under the umbrella organization Citizen Corps, which is funded in part by the Stafford Act;
an implementation of the federal CERT program, administered by a local sponsoring agency, which receives Stafford grant funding, and provides standardized training and an implementation framework to community members;
an organization of volunteer emergency workers who have received specific training in basic disaster response skills, and who agree to supplement existing emergency responders in the event of a major disaster.
Sometimes programs and organizations take different names, such as Neighborhood Emergency Response Team (NERT), or Neighborhood Emergency Team (NET).
