The 3 Steps to Begin Your Exam

The NBMTM uses Mettl, an online proctoring service, as a more efficient and convenient way to maintain integrity in certification exams. This means that you will have an online proctor for this exam. The service is fully integrated within myNBMTM portal and available Monday through Saturday.

Step 1: Connect your webcam

This exam will require the use of a webcam and microphone (internal or external). There are many options available for purchasing a webcam if you don’t already have one or if one is not built-in to your computer.

The NBMTM will record audio and video during the exam, so make sure you’re following the guidelines set by the NBMTM while testing. You should select a quiet, private space for testing.

Click TEST YOUR EQUIPMENT. A System Diagnostics Test will run to make sure you have the necessary requirements to take the exam, which includes video recording, audio recording, identity verification, and screen recording.

If you are missing something, it will alert you and tell you what the problem is. You can also perform a Re-Test when you have fixed the problem.

Step 2: Connect your proctor

After scheduling your test appointment, you will receive an email from Mettl confirming your exam date and instructions to access the online proctoring exam. On your exam date, click the link provided by Mettl in the appointment email and  start authenticating process. If you have problems connecting, please call 800-265-6038.

Step 3: Authenticate.

Test candidates verify their identity via webcam and government issued ID card. Proctors survey candidate surroundings and run diagnostic scans on candidate computers before beginning testing. Mettl automatically blocks screen sharing and remote desktop applications to prevent cheating.

  1. Make sure your webcam is plugged in and your speakers are plugged in and turned on.
  2. Be sure that no other program is running other that this browser window.
  3. Your call should begin immediately. If you lose connection or do not reach someone, press the “refresh” button on your browser. If a window pops up with a question, hit “allow”. You will be connected to your proctor via the window above.
  4. After verifying you are ready to take your exam, your proctor will help you start your exam.
  5. You are not allowed to leave sight of the webcam during your exam. If situation arise, please notify your proctor.
