Much research documents the systems of racism that undergird the rise of school choice policies and charter schools, racialized organizations that reproduce racial logics. While school choice policy gets enacted at the structural level to enable the formation of charter schools, policy also interacts with a localized neighborhood context where space must be allocated to the charter school. As race scholars show, space is itself racialized. How does this localized allocation of racial space shape intra-group dynamics in a predominantly Latinx neighborhood? Evidence for this study comes from two years of ethnographic participant-observation and informal conversations with parents in a traditional public school and a charter school in a large Northeastern city. Findings show how threats to the material boundaries of school space activate symbolic boundaries between parents from each school, drawing from racialized organizational identities of traditional public schools as representing neighborhood loyalty and anti-gentrification resistance positioned against charter schools as representing dominant whiteness, superiority, and social mobility. I conclude with a discussion of implications for broader studies of racialized space and organizations, culture, and collective action.
