The document discusses implementing schoolwide positive behavior support (PBS) at the classroom level. It outlines eight essential classroom features for PBS: clearly defining and teaching classroom expectations/rules; establishing and teaching classroom routines/procedures; providing high rates of positive feedback; using respectful redirection for errors; actively supervising students; giving multiple opportunities for students to respond; offering choice and varying activities; and ensuring academic success through appropriately leveled tasks. It provides examples and assessment criteria for schools to implement each feature with fidelity across all classrooms to improve social/behavioral outcomes and academic achievement.
