Help gender-expansive students feel safe, included, and affirmed at school. Gender-expansive youth need school policies and practices that focus on their happiness, health, safety, and privacy. Schools and teachers need concrete, accessible strategies and tools for supporting them. This book empowers every educator with those tools and strategies. Whether educators are brand new to or already familiar with gender diversity topics, they'll find opportunities to learn and practice in a judgment-free, low-stakes way. This must-have resource: helps educators understand, advocate for, and implement research-based best practices for gender-expansive youth; includes discussion prompts and reflection activities at the end of each chapter; shares strategies for affirming students through social transitions at school; supports educators by offering model language to address challenging questions related to gender in school communities; provides concrete actions educators can take to adopt gender-inclusive language and create learning environments that welcome students of all genders; and offers perspectives from gender-expansive youth in their own words. Written by an educator and advocate who was the founder of the Gender Inclusive Schools organization, this book grew from the resources and education-specific trainings he has developed working with school districts, independent schools, and educators throughout the United States and in Canada, the United Kingdom, and Australia. Digital content includes reproducible forms from the book.
