The CMRT certification evaluates a technician’s knowledge and skills in four key areas: maintenance practices, preventive and predictive maintenance, troubleshooting and analysis, and corrective maintenance.
This 50-question practice test is designed to simulate the types of questions found on the actual CMRT exam.
Read each question carefully and choose the best possible answer.
Good luck!
