Tier 1 systems, data, and practices support everyone across all settings. They establish the foundation for delivering regular, proactive support and preventing unwanted behaviors. Tier 1 emphasizes modeling, teaching, and acknowledging positive social, emotional, and behavioral (SEB) skills. Teams, data, consistent policies, professional development, and evaluation are essential components for these practices to work effectively.

The core principles guiding Tier 1 PBIS include the understanding that we can and should:

• Effectively teach appropriate SEB skills to all students

• Intervene early before unwanted behaviors escalate

• Use research-based, scientifically validated interventions whenever possible

• Monitor student progress

• Use data to make decisions
