This report describes the second module of an early intervention program for at-risk kindergartners who show the early signs of antisocial behavior patterns. The second module of the "First Steps" program describes a school intervention involving the target child, peers, and teachers that teaches an adaptive, prosocial pattern of school behavior. The Contingencies for Learning Academic and Social Skills (CLASS) program requires 30 school days for implementation and consists of three phases: Consultant (days 1-5), Teacher (days 6-20), and Maintenance (days 20-30). The intervention relies on a point system and rewards the whole class for the targeted student's behavior. Included in the report are descriptions of intervention agreements and responsibilities, implementation procedures, recycling procedures, strategies for trouble shooting, and behavior maintenance plans. Two flowcharts provide complete overviews of the intervention procedures. In addition, a graph provides a timeline of involvement for each of the major participants in the CLASS program. Appendices include an agreement form, a menu of rewards and praise statement for teachers, a menu of rewards and praise statements for parents, a daily summary chart, a class monitoring form, blank copies of individual green/red point cards, and a list of additional resources.
