One of the requirements of DART is in fact CERT training. CERT members are primarily used in their own neighborhoods. CERT training means you are as ready as you can be to help yourself, your family, and your neighborhood, and serves as the basic level of training for all community-based disaster volunteer teams in Ventura County. In a disaster, normal activities will be disrupted, police, fire, 9-1-1, and ambulances will be quickly overwhelmed, and may not be able to respond for 72 hours.
Residents need to be able to take care of themselves until the professional emergency responders arrive. One goal of the CERT program is to help residents respond to and assist others in need and do so effectively without placing themselves in unnecessary danger. 
Local government prepares for everyday emergencies. However, during a large disaster, the number and scope of incidents can overwhelm conventional emergency services. The Community Emergency Response Team (CERT) program is designed to educate Thousand Oaks residents and businesses about disaster preparedness for hazards that may impact their area and instructs them in basic disaster response skills.
Using the skills learned in the classroom and during exercises, CERT members can give critical support to their families, neighbors, and community immediately following a disaster when residents may initially be on their own and emergency services may not be available to help.
