Early Childhood PBIS refers to Positive Behavioral Interventions and Support (PBIS) implementation within early childhood settings. The Pyramid Model is a multi-tiered framework with a continuum of evidence-based practices to promote expected behavior, prevent problem behavior, and intervene when students need more support. (Including needs of all three tiers in the MTSS framework.) This model addresses the needs and contexts unique to programs serving infants, toddlers and preschoolers, including children in public school early childhood classrooms. It includes the practices, procedures, and data collection measures appropriate for young children and their families. Professional development is facilitated by AEA personnel who have experience providing professional development and coaching in the area of behavior and mental health support systems
