The Washington Interpreters Declaration (DID) is an international agreement that seeks to promote the use of sign language interpreters and other related services in the United States and abroad. It was created in 1988 by the International Association of Conference Interpreters (AIIC) and is a statement of principles and professional ethics. The DID set standards for the quality of interpreted services, and it encourages interpreters to strive for excellence in their work. It also outlines the responsibilities of the interpreter and the client, and it promotes collaboration between interpreters and the deaf and hard of hearing communities. The DID is divided into four main sections: Professionalism, Rights and Responsibilities, Quality of Service, and Cooperation and Collaboration. The DID is recognized by many international organizations, including the United Nations, and its principles are used in the training of interpreters all over the world.
