The original Social Skills Improvement System – Classwide Intervention Program (SSIS-CIP) was evaluated in a previous randomized controlled trial funded by the Institute of Education Sciences.  Approximately 100 classrooms and over 1,100 students participated in this study. We assessed multiple student outcomes and asked teachers about their views of the program. The PEAK project focuses on evaluating the newest edition of the program, which has been expanded to include additional units and digital resources.

Findings indicated positive social and learning behavior outcomes for students participating in the SSIS-CIP.

Second graders improved in social skills and internalizing behaviors (according to their teachers’ ratings). The greatest changes occurred in classrooms with students who had lower skills initially.

Second graders who had lower initial levels of engagement and motivation improved the most in these areas. Those who were receiving supplemental instructional services also demonstrated gains in math.

First graders demonstrated gains in social skills and approaches to learning (academic motivation and engagement).

Teachers generally had positive views of the program.
We also explored the total costs of implementing the SSIS-CIP including training, materials, and time.

The average total cost for implementing the program in the primary grades is approximately $19 per student.
