The Frank Porter Graham Child Development Institute at UNC Chapel Hill (FPG) partnered with the North Carolina Department of Health and Human Services Division of Child Development and Early Education (NCDHHS DCDEE) to assess a pilot implementation of the NC Preschool Pyramid Model (Pyramid Model). This social-emotional coaching program is designed to enhance the use of evidence-based practices to support social-emotional development for NC Pre-K classrooms located in private center-based preschool programs in one urban and three rural counties. The two-year evaluation involved eighteen focus groups and interviews with coaches, administrators, teachers, and parents/guardians, alongside measures of teacher-child interactions and child outcomes across 40 participating public and private Pyramid and Business-as-Usual classrooms with a total of 253 children. The outcomes evaluation examined the extent to which independently collected measures of teacher-child interactions and child social skills, behavior problems, and emotion knowledge are associated with implementation of the Pyramid Model or not across public and privately located NC Pre-K classrooms. Study findings reflect that classrooms were prepared for implementation and were more favorable than previous studies, and similar effects may be observed upon scaling but with classrooms that are likely less ready than those reflected in this study. Finally, scaling is contingent on adequate statewide staffing, planning time, and related resources, particularly for classrooms located in private center-based settings.
