School should be a safe, welcoming environment for every student—whether transgender, cisgender, or nonbinary—but not all states have nondiscrimination laws protecting students from discrimination based on gender identity and expression. In Washington state, however, the law is clear: Discrimination based on gender identity and expression is explicitly prohibited. But what does this mean in practice? And, more importantly, how do schools ensure they are consistently upholding this legal obligation and maintaining a gender-inclusive environment for all students? This training will provide an overview of the legal protections in place for Washington K-12 students, define some key (and constantly evolving) terms, share best practices, and answer the most frequently asked questions that we receive from schools about how to create and maintain a gender-inclusive learning environment for all students.
