This bill establishes a new section in chapter 28A.155 RCW that clarifies the burden of proof in special education due process hearings. It stipulates that, in most cases, the school district will bear the burden of proof, including both persuasion and production, when involved in hearings related to a student's identification, evaluation, educational placement, or provision of a free appropriate public education. However, if a parent seeks tuition reimbursement for a unilateral placement, the burden of proof shifts to the parent to demonstrate the appropriateness of that placement.

Additionally, the bill specifies that the burden of proof must be met by a preponderance of the evidence, ensuring a clear standard for these hearings. It also defines "due process hearing" in accordance with the federal Individuals with Disabilities Education Act, aligning state law with federal standards.
