This short course provides an overview of what we mean when we use the term “ally,” which is a person who uses their privileged social identity to empower, support, and defend individuals and groups who are being marginalized. Learners gain an understanding of the different types of allies: a confidant, champion, amplifier, sponsor, or upstander. Allies play important roles in school environments, helping children, youth and staff members feel safe and included, leading to a more positive culture and climate.
