Earning the CMI Credential

To be granted a CMI credential individuals must meet all of the eligibility prerequisites and pass BOTH the written and oral examinations. The CMI credential is awarded in the specific languages for which the oral exam is passed (for example CMI-Spanish, or CMI-Korean).

The National Board only awards the CMI credential to individuals who meet the eligibility criteria and successfully complete the written and oral examinations.

*Russian, Mandarin, Cantonese, Korean and Vietnamese interpreters

FOR those interpreters who want to be certified in Russian, Mandarin, Cantonese, Korean or Vietnamese ONLY,  (this no longer applies to Spanish as the three years have passed) please note:

Interpreters who have been working as medical interpreters for at least one year (recent experience within the last two years), and can provide proof with a signed letter of employment on company letterhead, with a hire date, are eligible to take the CMI written exam and the oral exam for Russian, Mandarin, Cantonese, Korean and Vietnamese. Oral exams in other languages will be added and candidates will have this same opportunity, with an ending date three years after the oral exam in their language becomes available. 

Candidates must ensure that their supervisors (HR or direct) include the language interpreted and the dates of employment. Multiple letters of employment are accepted, and the employment can be as an independent contractor, volunteer status, or regular part-time or full-time employee.

(Note: Other languages will have the three years from the time their exam became available to supply the letter described above.)
