The purpose of the Prevention Technology Transfer Center (PTTC) Network is to improve implementation and delivery of effective substance misuse prevention interventions, and provide training and technical assistance services to the substance misuse prevention field.  We do this by developing and disseminating tools and strategies needed to improve the quality of substance misuse prevention efforts; providing intensive technical assistance and learning resources to prevention professionals in order to improve their understanding of prevention science, epidemiological data, and implementation of evidence-based and promising practices; and, developing tools and resources to engage the next generation of prevention professionals.
