I teach in a PBIS school. I was very anti-PBIS before starting at my current school. Mostly because I don't believe in extrensic rewards, treasure box, etc.. However, I have to say, the way PBIS is done at my school is fantastic. I completely love it, and our hard Title 1 population is super well behaved (for the most part). It helps that my school is brand new (built last year), so we set the stage for all structures, behavior expectations, etc.. Teachers had no choice but to "buy in", so that helps. Every classroom is required to do class dojo and a clip chart system (ok, i don't love that part). Each grade level has a point goal for students that they aim to earn each week. Teachers decide individually what students can do with their points (class parties, eat lunch with the teacher, etc..) School wide, we do "All green, all the time" parties for kids that have their clips on green every day, 1x/quarter. All the teachers stand in the hallways with music instruments and clap, yell, and cheer for the kiddos as they walk down the hall to get their treat (which varies, sometimes its just a snack, sometimes it's time in the gym, a dance party in the cafeteria, etc..) For kids that don't get to go to the party, they have to participate in a "re-teach". So, not focusing on punishment, but more just sitting down and re-teaching whatever behavior they had difficulty with. We have common structures and rules for hallway behavior, restroom & cafeteria behavior, etc.. Teachers are required to turn in their behavior data every month. Our PBIS coach goes into classrooms that are having less than 80% of students on green during the week and helps the teacher with positive reinforcement, coaching on using the clip chart appropriately, etc.. Anyways, I could go on and on, but really I love it. I know our teachers get bogged down with the data portion especially, BUT it helps everyone stay accountable so that teachers aren't just having kids clip down for nothing.
