The purpose of this article is to provide a new social justice conceptual framework in school counselling. Although principles of social justice have been discussed in the counselling field, more discussion on the principles is needed to help school counsellors improve their counselling services for all students. This comprehensive literature review suggests eight social justice principles: (1) Constant self-examination; (2) appreciating students' worldviews and life experiences; (3) focus on strengths; (4) liberatory consciousness; (5) sharing power; (6) reciprocal collaboration; (7) taking action; and (8) leaving students with tools. Challenges to implementing these principles are discussed and recommendations for school counsellors are provided.
