"Fast Track" is a comprehensive intervention designed to reduce conduct problems and promote academic, behavioral, and social improvement. The program's components include the "Promoting Alternative THinking Strategies" curriculum, parent groups, parent-child sharing time, child social skills training, home visiting, child peer-pairing, and academic tutoring. The What Works Clearinghouse (WWC) identified one study of "Fast Track" that both falls within the scope of the Children Classified as Having an Emotional Disturbance topic area and meets WWC group design standards. This study meets standards without reservations and included 891 students who were identified in kindergarten as being behaviorally disruptive and at high risk for long-term antisocial behavior in 54 schools in four locations. For children classified as having an emotional disturbance (or children at risk for classification), "Fast Track" was found to have potentially positive effects on emotional/internal behavior, reading achievement/literacy, external behavior, and social outcomes.
