Permitted Materials for Your Exam:

  1. There are no materials permitted for your exam.

The National Board currently offers the Hub-CMI and the CMI (Certified Medical Interpreter) credentials. The Hub-CMI is a credential available to all interpreters, regardless of target language. If there's a CMI credential available in your target language, your Hub-CMI will expire in two years after you pass the written exam with no option for renewal.

The CMI (Certified Medical Interpreter) credential is offered in six languages: Spanish, Cantonese, Mandarin, Russian, Korean, and Vietnamese. After achieving the Hub-CMI, you will be allowed 2 years to complete the oral assessment for the CMI certification.


Results: You will receive your written exam results right away. For online tests, only a percentage score will be available. To pass the test, your percentage score must be at least 75%.

Test Environment, System, and Network Issues: By accepting the use of online proctoring, you assume all risks associated with network, technical, or computer-related issues, as well as your choice of testing environment. If you fail to successfully complete the test due to those factors, you are responsible for the cost of any retakes.

Retakes: Candidates who do not pass the written exam may re-take the exam after a 3-month waiting period. The initial exam and re-test fees and application procedures are the same.  After 3 retakes you will be permitted 1 attempt per calendar year. You may take the exam online once, but for all additional exams you are required to test at a testing center. You will be permitted to reapply and earn your Hub-CMI only one time after your original expiration date.  You should attempt the oral exam at least once before your first Hub-CMI expires.

 Fees Expiration and Refunds Policies: The exam fees are non-refundable, and an exam fee will expire after one year if the exam has not been taken. There will be a rescheduling fee of $25.
