Learning "how to be a Haut Gap student" is one of the basics at Charleston's Haut Gap Middle School. Along with reading, science, and mathematics classes, every student at Haut Gap Middle School takes a course in how to be a Haut Gap student. For most students, the class is 40 minutes a day for nine weeks. But it can last 18 weeks for students who need extra time to nail concepts such as how to own up to mistakes, accept feedback, and apologize appropriately. Those lessons are part of a schoolwide approach to addressing student behavior that Haut Gap has used for about five years: Positive Behavioral Interventions and Supports, or PBIS.
