In 2004, the first Respectful Language bill (HB 2663) was introduced by the Self Advocates in Leadership (SAIL) advocacy group. The bill focused on using people-first language in new and revised laws.

In 2009, Washington State began formally updating its statutes to replace outdated terminology with the term “intellectual disability.” Through House Bill 1835, the Legislature directed the Code Reviser to review and update language throughout the Revised Code of Washington to reflect more respectful and current terminology. This effort recognized the importance of using language that reflects dignity and aligns with evolving understanding in the disability community.

In 2010, a third respectful language bill (HB 2490) was passed. This law, developed by the Code Reviser, identified more than 30 instances in state law where outdated language was still being used and required updates to ensure consistency with respectful language standards.

These changes was part of a broader national movement toward person-first language and away from terms that had become stigmatizing over time. Advocacy organizations, self-advocates, and families across the country were calling for more respectful language in law and policy. Washington’s actions during these years aligned state statutes with these values and with similar federal efforts such as Rosa’s Law. The update marked an important step in reinforcing respect, inclusion, and recognition of people as individuals first.
