This dissertation involved a mixed method study on discipline practices in a single urban school district. This was a novel investigation that engaged stakeholders (administrators, teachers, school professionals, and students) to view, analyze, and interpret discipline data from their district and to explore the underlying causes of discipline outcomes. I found disproportionate discipline of students of color and disproportionate discipline for minor offenses. Stakeholders views resulted in a model in which social ecological systems drove the discipline system and undergirded the disparate and discriminatory practices. Interpretations of the findings are discussed.
