What’s on the TMC Exam?

Questions: 160
Time limit: 3 hours

First, let’s talk about the questions on the exam. There are 160 multiple-choice questions total, but only 140 of the questions will count toward your score. Why is that?

Unscored Questions
The 20 unscored questions on the TMC exam are called “pretest” questions. These are added to the exam to determine if they’re good enough questions to add to future versions of the test.

The trick is that you won’t have any way of knowing which questions are scored and which ones are pretest. They will appear just like the scored questions throughout the test.

The time limit for the exam is 3 hours. There aren’t any scheduled breaks, but you’re free to take restroom breaks as needed.

Let’s take a closer look at the different sections of the TMC exam.

TMC Scores

For each question you answer correctly, you will receive one point toward your score. The number of points you get by the end of the exam is called your raw score. Your raw score determines your pass or fail status after comparison to the cut score.

If your raw score reaches 88, which is the low cut score, you will be awarded the CRT credential. If your raw score reaches the high cut score, which can fluctuate, you will receive the CRT credential and become eligible to take the CSE.

Retaking the Exam

If you didn’t get a passing score on your first try, that’s okay! You can retake the test two more times with no waiting period between attempts. After your third attempt, you’ll have to wait 120 days before trying again.

Keep in mind that you will have to pay the full testing fee every time you retake the test.
