Social justice education emphasizes how schools can better serve traditionally marginalized students. This case study examines the pursuit of social justice education in an unlikely setting: a Catholic elementary school that both espouses inclusion of all children and effectively includes children with a wide range of disabilities. The article focuses on the way a school principal understands the concept of inclusivity and how this "epistemology of inclusivity" enacted by the leader impacts the pursuit of social justice in the school. The study illustrates that an epistemology of inclusivity can at once embolden and delimit the social justice practices. (Contains 2 tables.)
