Exclusionary discipline practices (EDPs) have been linked to poor academic performance and student dropout rates. Research shows that students suspended, expelled, or placed in alternate learning environments fare worse academically than their peers. This qualitative case study explores the experiences of classroom teachers in Northwest Louisiana with students who have been disciplined using Exclusionary Discipline (EDPs) at a middle school grade level. This study aimed to explore the experiences of classroom teachers with students disciplined using EDPs. Seven participants with more than three years of experience and previous experience with suspended students were selected. The study used explanation building to analyze the data collected and provide an understanding from a teacher's perspective on how students exposed to EDPs behave in a classroom setting and why EDPs have resulted in poor academic performance and minimal deterrence in behavior. The findings suggest suspended students are behind academically and repeat the same negative behaviors. The study found that EDPs have been associated with adverse outcomes, including poor academic performance and minimal deterrent effect on negative behaviors. Teachers' experiences with EDPs were examined, and four themes were identified: suspensions and academics, the influence of suspensions on peer behavior, parental involvement, and outside influences on students' behavior in the classroom. The findings suggest that schools should revamp their handling of student discipline and consider building positive relationships among students, teachers, and parents. Schools should also examine return-to-school guidelines and implement preventative discipline programs, such as PBIS and multi-tiered systems of support and restorative practices, to reduce the academic gap between consistently suspended students and those who receive more academic instruction.
