Tier 1 includes universal management strategies designed to meet the needs of all students and develop a common language and focus for all school staff, families, and community members. Universal or Tier 1 strategies are designed to be implemented consistently and efficiently across all school settings, classroom and non-classroom (e.g., cafeteria, hallways). This includes teaching specific behaviors or social skills that will lead to success in school, providing frequent positive reinforcement for expected behavior, consistently addressing social errors, and arranging teaching and learning environments to ensure success for all. This level should meet the needs of approximately 80 percent of a school’s student body.
