The six Washington Chapters are designated based upon geography and member population with the Graduate Student Chapter open to all student members.
Each member is automatically a member of the Chapter in which they are employed. Members who reside in one Chapter and are employed in another may elect a primary affiliation and be a member of both chapters. Chapters may specify their own governance structure and election procedure for representation on Council.
Because of the distance each chapter covers, members are now able to connect to each other online by loggin in and participating in their Chapter Blog.
