TMC Exam Registration

To register for the exam, you must submit an application on the NBRC website. This application should include all necessary documentation to support your eligibility as well as the $190 examination fee.

Once your application is approved, you will receive instructions on how to schedule your exam appointment. You may choose to schedule an in-person appointment at a testing center or an online appointment via live remote proctoring (LRP).

LRP

Before registering for the remote proctor option, make sure your equipment meets the requirements. LRP requirements include the following:

• A desktop or laptop computer running at least a Windows 7 or Mac OS X operating system
• Google Chrome browser
• A webcam and microphone
• Minimum 466 kb/s bandwidth
• 2 GB RAM and 1 GB free disk space
• A minimum screen resolution of 1368×768

Test Day

On the day of your exam, you must present one form of valid government-issued photo identification with your signature. The name on your registration must match the name on your identification. For both delivery methods (on-site and remote), you should arrive or be logged in 30 minutes before your testing appointment.

In-person Testing

After you have provided your ID, your picture will be taken and your palm will be biometrically scanned for security purposes. You will then be asked to store all personal items in a secure locker.

Once your personal items are stored, you will be led into the testing room and given a short tutorial on the testing system. Once this step is complete, your exam will begin.

LRP

On the day of your exam, ensure that your testing area is clear of reference materials, your cell phone, and food or drink containers. You are permitted two pieces of blank paper and a writing utensil for writing notes. You must use the Google Chrome browser and enable cookies. Ensure you can move the webcam around for the proctor so they can view your area. Present your ID and scratch paper for inspection and follow any directions provided.

You can launch the examination up to 30 minutes before your scheduled appointment. You cannot leave the webcam’s view during your exam, use other monitors, or talk to anyone. If the proctor observes questionable behavior, your exam will be canceled.

How the TMC Exam is Scored

For each question you answer correctly, you will receive one point toward your score. The sum of correct responses is called your “raw score.” Your raw score determines your pass or fail status after comparison to the cut score.

If you achieve the low cut score (88), you will be awarded the CRT credential. If you meet the high cut score, which can fluctuate, you will receive the CRT credential and become eligible to take the CSE.

Retaking the TMC Exam

If you failed the exam, you may take it two more times with no waiting period between attempts. After the third attempt, you must wait 120 days before trying again.
