CDI Certification Process

June 23, 2016, RID established the Center for the Assessment of Sign Language Interpretation, LLC (CASLI) to take over the administration and ongoing development and maintenance of exams. Eligibility requirements and the credentialing of any and all individuals will remain the responsibility of RID. With this shift in responsibilities candidates will need to contact both RID and CASLI during different times in the certification process. For more information, visit www.casli.org.
