Student affairs work--like higher education--is fundamentally about change. Principally, the change work performed by student affairs practitioners is about supporting the growth and development of individual students and student groups. Increasingly, that work has called for practitioners to become more active in working to change higher education so that it lives up to its radically democratic, inclusive ideals. This means adopting new strategies to transform student affairs staff, students, and institutions, and drawing on insights from critical, liberatory theories. This text represents an effort to describe and document these practices of intentionally centering critical theories.The first section of this text examines the ways that critically-minded practitioners lead through equitable, liberatory frameworks, offering important models for reimagining the future of higher education. In the second section, the editors take up thinking and acting to support the development of critical consciousness in students, providing examples of programs, initiatives, and student support offices that center social justice in their work, and foster a critical lens through their interactions with students. In their conclusion, the editors provide a model for critical praxis, offering enduring strategies for practitioners seeking to incorporate critical, socially just praxis into their everyday work, and defining areas for future research and praxis, including identifying strategies for effective assessment of critical praxis, and modalities for "scaling up" the work for maximal impact.
