What the Course Entails and Exam Details

This comprehensive course delves into the core technical and managerial pillars required to build and sustain a reliable operation. The syllabus is rigorous, covering both theoretical concepts and practical applications. Key topics include:

  • Reliability Fundamentals: Core concepts of failure patterns, understanding hidden failures, and calculating key metrics like MTBF (Mean Time Between Failures) and MTTF (Mean Time To Failure).
  • Asset Strategy Development: Learning how to prioritize assets using Criticality Analysis and Pareto Analysis, and applying tools like FMEA/FMECA (Failure Modes, Effects, and Criticality Analysis) and RCM (Reliability-Centered Maintenance) to develop optimal maintenance plans.
  • Condition Monitoring: A technical overview of various technologies (vibration analysis, ultrasound, oil analysis, thermography) and how to integrate them into a cohesive condition-based maintenance program.
  • Defect Elimination & Precision Maintenance: Techniques for root cause analysis (RCA) to eliminate recurring issues and the importance of precision skills in alignment, balancing, and fastening during installation.
  • Life Cycle Cost Analysis: Understanding the total cost of ownership of assets from design to retirement.
  • Culture Change & Data Analysis: Strategies for motivating teams toward reliability and using statistical tools (like Weibull analysis) to interpret failure data.

  • Time Limit: You are allowed 3 hours to complete the exam.
  • Passing Score: The passing grade is a minimum of 70%.
  • Rules: The exam is closed-book and proctored, ensuring the integrity of the certification.


How to Study and Exam Centers

Preparation is crucial for success in the ARP-E exam. A combination of structured learning and active practice is recommended:

  • Authorized Training: Mobius Institute and its global network of Authorized Training Centers provide 4.5-day training courses that directly cover the exam syllabus. While not strictly mandatory for everyone, attending this training is highly recommended as it provides the foundation for the exam.
  • Active Practice Exams: Utilizing specialized practice exams is essential. These mock tests help you become familiar with the question format, identify weak areas in your knowledge, and refine your time management skills.
  • Mobius Knowledge Center: Mobius provides access to a knowledge center with reference materials, glossaries, and videos that are excellent for revision.
  • Flashcards: Creating flashcards for key definitions, formulas (MTBF, availability, etc.), and reliability tools (FMEA vs. RCM) can strengthen your recall.

Exam Centers: The exam can be taken through two primary routes:

Directly After Training: If you attend a public classroom or live stream course, the exam is typically offered on the final day at the same location.

Via Proctoring: For those not attending a physical class, Mobius offers the exam through registered invigilators (proctors) at authorized training sites globally, or through secure online proctoring services (often via portals like Pearson VUE or Mobius’s own testing environment), allowing you to take the test remotely from your office or home.
