When you join your local PTA or PTSA, you become part of the Washington State PTA and the National PTA. Your voice joins tens of thousands across Washington and millions across the United States as advocates for children. A large portion of your membership in the West Seattle HS PTSA goes to support this strong voice advocating for children at the local and state level through a combination of grass-roots advocacy and a full-time staff to coordinate those efforts and represent the Washington State PTA in Olympia.
