An ally is an individual who speaks out and stands up for a person or group that is targeted and/or discriminated against. An ally works to end oppression by supporting and advocating for people who are stigmatized, or treated unfairly because of who they are. In this context, Allies are referred to as people who do not identify as LGBT (lesbian, gay, bisexual and transgender) students, but support this community by standing up against the bullying and harassment LGBT youth face in school. Allies should be celebrated for their contribution to making schools safe for LGBT students. During Ally Week, student organizers plan events and actions to identify, support and celebrate Allies, with particular attention to those Allies who stand up against anti-LGBT name-calling, bullying and harassment in schools. This guide provides tips on how educators can participate in Ally Week and support students' efforts, including: taking the Ally Week pledge; asking other school staff to take the Pledge; intervening if Ally Week participants are called names, bullied or harassed; supporting students' Ally Week efforts; and dedicating class time during Ally Week to discuss anti-LGBT bias in schools and the need for Allies. A Pledge form; list of Ally Week resources; and a list of other important resources are provided.
