Exclusionary discipline is a consequence of behavior for students who break the student code of conduct. Extensive research about the effects that exclusionary discipline can have on secondary students, as evidenced by reduced graduation rates, has been conducted; but, research studies investigating the potential impact that exclusionary discipline can have on the academic outcomes of students at the elementary level have yet to be conducted. The use of exclusionary discipline is overrepresented in students with low socio-economic (SES) backgrounds; large populations of low-SES students are educated at Title I schools that receive federal funding to support academic growth. The purpose of this causal-comparative, non-experimental study was to investigate the impact that exclusionary discipline consequences had on fifth-grade students who attended all of the elementary schools within one north Texas school district during the 2018-2019 school year. In conjunction with the examination of the effect that the assignment of exclusionary discipline consequences can have on the academic outcomes of fifth-grade students, student-specific variables such as attendance at a Title I or non-Title I campus, student race, timing of exclusionary discipline assignment, and students in various educational programs were investigated to determine the potential impact of exclusionary discipline on fifth-grade students by student subgroup. Archival data such as the number of days a student spent in exclusionary discipline, student demographics, and students' scores on the State of Texas Assessments of Academic Readiness (STAAR) standardized test scores in reading and mathematics were utilized. A summary of findings, implications for administrators and schools, and recommendations for future research is also presented.
