Program-wide implementation of the Pyramid Model: Supporting fidelity at the program and classroom levels

• Program-wide supports include leadership commitment, staff buy-in, and professional development • Early childhood programs improve implementation of program-wide supports with external coaching • Program-wide supports improve teacher implementation of Pyramid Model practices Many early childhood programs are not prepared to meet the needs of children who have significant social, emotional, and behavioral challenges. Program-Wide Supports for Pyramid Model Implementation (PWS-PMI) provides a systematic approach to supporting early childhood programs using Pyramid Model practices and enhancing children's social-emotional outcomes that is grounded in implementation science. We designed the current study to test the PWS-PMI intervention and examine its feasibility of implementation in community-based early childhood programs serving children from low-income environments. In this study, we found programs increased their implementation of PWS-PM and improved classroom practices after only one year of support. Our findings indicate a program-wide approach is effective, although more time and support will be necessary to sustain high fidelity implementation and produce robust effects on children.
