The Certified Maintenance and Reliability Technician (CMRT) credential, awarded by the Society for Maintenance and Reliability Professionals (SMRP), recognizes technicians who demonstrate mastery of maintenance fundamentals, predictive technologies, and reliability principles. Whether you work in manufacturing, utilities, or process industries, passing the CMRT validates your technical skills and advances your career.
This free CMRT practice test PDF covers all the major exam domains — from lubrication management and mechanical systems to CMMS usage and failure mode analysis.

The CMRT exam is built around the SMRP Body of Knowledge for maintenance and reliability technicians. Understanding the domains and their relative weightings allows you to prioritize your study time effectively.
This domain covers PM scheduling strategies, time-based versus condition-based maintenance, work order execution, job planning and parts staging, and corrective maintenance procedures. You must understand how to reduce unplanned downtime through structured PM programs.
The CMRT exam puts significant weight on predictive maintenance (PdM) tools. Topics include vibration analysis (waveform, spectrum, bearing fault frequencies), infrared thermography for electrical and mechanical inspections, airborne and structure-borne ultrasound for leak detection and lubrication monitoring, and oil analysis (viscosity, particle count, wear metals, contamination).
Lubrication is a major CMRT domain. You need to understand oil viscosity and ISO grades, grease selection and compatibility, contamination control methods, re-lubrication intervals, and how improper lubrication causes premature bearing failure. Correct lubrication practice is one of the highest-impact maintenance activities.
This section covers motor testing (insulation resistance with a megohmmeter, winding resistance, surge testing), power quality issues (harmonics, voltage unbalance), variable frequency drive basics, and lockout/tagout (LOTO) procedures for electrical equipment.
Mechanical topics include rolling element bearing selection, installation, and failure analysis; shaft coupling types and alignment (angular and parallel misalignment); belt and chain drive inspection; seal selection (lip seals, mechanical seals, packing); and precision maintenance techniques like laser alignment and balance.
The CMRT exam tests your ability to use a computerized maintenance management system effectively — creating and closing work orders, tracking parts inventory, generating PM schedules, and analyzing equipment history to identify chronic failures.
Reliability topics include failure mode and effects analysis (FMEA), reliability-centered maintenance (RCM) concepts, P-F interval (potential failure to functional failure), overall equipment effectiveness (OEE) calculations, and mean time between failures (MTBF) and mean time to repair (MTTR) metrics.
