Welcome Interpreters!

The Board Directors and staff of the National Board of Certification for Medical Interpreters (National Board), welcome all of you who are interested in becoming a Certified Medical Interpreter (CMI).  Medical interpreters do very important work and it is an honor to serve you as your certifying entity. We also appreciate all the stakeholders who help make certification a success.

The National Board has expanded to a total of six languages - Spanish, Russian, Cantonese, Mandarin, Korean and Vietnamese. We have welcomed several new very talented Board Directors who will be helping to lead in advancing the certification program.  Demand for certification is skyrocketing, with some states and health care entities now requiring certification.

In our quest to make certification ever more accessible, we now offer online proctoring, which allows the prospect CMI the convenience of taking both the written and oral tests from any location, including the convenience of their own home.  We invite you take this important step and join the CMI family today!
