Expanding protections for certain students to promote inclusivity in public schools.

HB 1855 amends Washington state law to prohibit public school discrimination based on additional protected categories, directly affecting students and schools statewide. It adds specific definitions for terms like gender identity, gender expression, neurodivergence, immigration status, and homelessness, then updates the existing anti-discrimination statute (RCW 28A.642.010) to explicitly include these categories. The law expands protections beyond current federal standards, ensuring schools cannot discriminate on these grounds in educational settings. It focuses on creating inclusive environments by addressing barriers to learning for marginalized students, including LGBTQ+ youth and neurodivergent students. The policy change is a direct update to school anti-discrimination rules, not a new program or funding measure.
