Oklahoma Certified Interpreters (OCI) are individuals who have been authorized by the Oklahoma Department of Human Services (OK DHS) to provide language services in a variety of settings. OCI interpreters are certified in accordance with the state's Interpreter Certification requirements, which include passing an interpreter certification exam, acquiring a professional liability insurance, and completing a minimum of 20 hours of continuing education every two years. OCI interpreters are certified to facilitate communication between individuals who are Deaf, Hard of Hearing, or Limited English Proficient (LEP) and the people they are interacting with. There are three types of OCI interpreters: Certified Interpreters, Qualified Interpreters, and Provisional Interpreters. Certified Interpreters are individuals who have passed the interpreter certification exam and have completed all the requirements for certification. Qualified Interpreters have passed the interpreter certification exam but have not yet completed all the requirements for certification. Provisional Interpreters are individuals who have not yet passed the interpreter certification exam but have completed all the other requirements for certification. All three types of OCI interpreters are required to complete at least 20 hours of continuing education every two years in order to maintain their certification.
