In this article, we introduce a special collection of research articles that consider the processes and consequences of school choice across different social and spatial contexts in order to better understand the relationship between school choice and stratification in educational opportunity. This special issue presents a wide range of studies that examine geographical configurations, locations, scales, and relationships, all of which shape and are shaped by school choice. We summarize the diverse theoretical perspectives and themes. We also highlight the articles' key results and new contributions related to issues such as inter-district school choice, open enrollment school choice programs, diversification of curricular-related activities among EMO-operated schools, and geographic variation in achievement of the charter school sector
