Strong, proactive classroom management skills coupled with clearly defined expectations facilitate effective instruction and create an organized and collaborative learning environment for students' equitable access to instruction. When all school faculty and staff have a common set of agreed-upon expectations for student behavior, students may benefit from consistent behavioral instruction, feedback, and disciplinary responses (Valenti & Kerr, 2015). Essentially, commonly agreed-upon expectations of important behaviors are more likely to create an environment where all students may experience success (Lane, Wehby, & Cooley, 2006; Scott, 2007). Organizing clearly defined, explicitly taught, schoolwide behavioral expectations into a matrix is helpful in facilitating consistency in a school environment. The matrix is a grid with columns representing key school settings (e.g., classroom, hallways, cafeteria), rows representing expectations (e.g., Be Responsible, Be Respectful), and cells indicating the specific behaviors for each expectation and setting (e.g., eat your own food, throw out your trash). Moreover, the matrix is part of a tiered prevention plan and defines the broad social expectations, operationalizing each expectation with observable behaviors for each school setting. Such expected behaviors, when selected with input from all stakeholders-faculty and staff, students, and parents-represent shared community values and promote equitable access to instruction and reinforcement in all domains (e.g., academic, behavioral, social-emotional). Schoolwide expectations provide common language for all adults and students to use, allow all adults (e.g., related service providers, special education teachers, office staff, and paraeducators) to teach expectations (formally and informally through personal interactions) to students as they would academics, and to reinforce expected behaviors 786787R SEXXX10.
