High school graduation represents a pivotal milestone with far-reaching implications for an individual's future in social, economic, professional, and personal spheres. Despite its significance, only approximately 85.5% of students in the United States successfully earn their diploma each year, with groups such as black, Hispanic, American Indian/Alaskan Native, English-language learners, students with disabilities, and homeless students experiencing disproportionately lower graduation rates. Efforts to understand and address these disparities have led to interventions such as school choice. This approach allows students to select their educational institution rather than being limited by residential zoning. Research indicates potential benefits, including enhanced academic performance, reduced absenteeism, and decreased disciplinary issues. This study investigates the impact of school choice within a public charter school system in North Georgia on high school graduation rates while considering demographic variables. The system comprises six elementary schools, one middle school, and one high school, each offering distinct educational approaches. Findings from this study reveal that attendance at the International Academy, irrespective of demographic background, correlates with a lower likelihood of graduating within four years compared to other schools. Additionally, factors such as being black, being an English-language learner, having a disability, being male, or attending multiple elementary schools are associated with decreased graduation rates. These findings emphasize the multifaceted nature of graduation disparities, suggesting that while school choice plays a role, other factors like language proficiency and demographic characteristics significantly influence outcomes. Further research is needed to comprehensively understand and address these disparities in educational attainment.
