The Oklahoma Interpreter Certification and Resource Center is the state certifying body for Oklahoma "sign language" interpreters. The ICRC uses the Quality Assurance Screening Test to evaluate the proficiency of individuals interested in becoming employed as interpreters for the deaf in the state of Oklahoma. You may download the application for testing or contact the ICRC Program Specialist. All ICRC Interpreters are required to know and adhere to a set of Code of Professional Conduct as well as the Levels of Limitations for Oklahoma sign language interpreters. The ICRC maintains a list of all Oklahoma ICRC certified interpreters.
