A number of communities have adopted a "train the trainer" approach. These efforts train supervisors or a small group of staff who then go back and serve as "trainers" for other staff in their organizations. This approach has several benefits. Internal training experts can reduce training costs associated with bringing in an outside training expert or sending a large number of staff to training. It also may be easier to coordinate and schedule trainings that are conducted internally. As previously noted, some agencies are more receptive to training by someone from within the agency.
