Oral Exam - Testing at a Site

Oral examinations are available in the following languages: Spanish, Russian, Cantonese, Mandarin, Vietnamese, and Korean.

2. Take the Practice Test

The National Board recently made a practice test in order for candidates to become more familiar and comfortable navigating through our oral exam. The practice test can be helpful to practice the format of the test before taking it.

The practice test is only to help candidates with test navigation. It won’t help you to prepare for actual interpreting in a medical context. The role play scenarios on the practice test are not necessarily consistent with the types of role play scenarios on the actual oral exam.

To take the practice test, make sure you are using a PC computer. Go to the testing site: http://hosted.owlts.com/ and log in using the following username and password:

username:          practicetest

password:           practicetest

Please remember that it is your responsibility to know how to navigate through the oral exam, including how and when to record your renditions and request repetitions. If you fail to correctly navigate through the oral exam your score will be negatively impacted.

3. Schedule Your Exam

Email your program advisor and say that you are ready to schedule your oral exam and which testing site location you want.

If you do not know who your advisor is, send an email to [email protected] and state in the email that you are ready to schedule your oral exam. Include the following information in the email: your full name, complete contact information, which language you interpret, the date you passed the written exam, and the location where you want to take your oral exam. DO NOT CALL.

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 certification available in your target language, your Hub-CMI credential will expire in two years with no option for renewal.

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

Results: You will be notified of test results by email within 6-8 weeks. The passing scores for the oral exam for Cantonese, Korean, Russian and Spanish is 70%. The passing score for Mandarin is 80% and for Vietnamese it is 65%.
