Become a CASLI Test Site – for the CDI Knowledge Exam

CASLI Test Site Application

The Center for the Assessment of Sign Language Interpretation (CASLI) administers CDI Knowledge Exams through a system of test sites located throughout the country. The test sites administer the Knowledge Exams year-round on a first come first serve basis, depending on availability of the site.

*The NIC Exams are currently administrated by Castle Worldwide and PSI/Comira.

Hosting a test site and administering the exams involves a commitment of time and facilities; however, it is a valuable contribution to your fellow interpreters and can be a very rewarding experience.
