The paper, one-third of which consists of appendixes, examines the emergence, development, and growth of the Registry of Interpreters for the Deaf, Inc. The literature is reviewed relative to the historical, philosophical, and general forces bearing on the evolution of sign language into a formal language, which was a prerequisite to the organization of sign language interpreters. Organizational data on the Registry of Interpreters for the Deaf, Inc. are provided, including its beginnings, development, growth, and precipitous rise in importance and scope. Aspects touched upon include certification, the deaf interpreter's role, postsecondary programs for deaf people, legislation concerning the use of deaf interpreters, and the shortage of deaf interpreters. The developing interrelationships that occurred as social forces caused a sign language upheaval are traced, along with subsequent side effects. Such aspects as deaf militancy, sign language classes for professionals, and the accelerated usage of pidgin sign language are discussed. Among the appendixes are a code of ethics for deaf interpreters, standards and criteria for sign instructors guidance network certification, a suggested fee schedule for deaf interpreters, and a bibliography.
