- The exam is open book: bound references are allowed, and a basic scientific calculator is built into the computer-based exam.
- The 2025 Body of Knowledge sets five areas: Reliability Fundamentals, Risk Management, Probability and Statistics for Reliability, Reliability Planning, Testing, and Modeling, and Lifecycle Reliability.
- ASQ reports a scaled score. This kit is independent practice and uses 70% as its own target.
ASQ (the American Society for Quality) runs the certification; this kit is independent of it.

Why these questions are demanding
We do not claim they are harder than anyone else's, because you cannot check that. Here is what you can check.
- The current Body of Knowledge. Every question is tagged to one of the five areas of the 2025 edition, in the proportions of the scored exam, and every result breaks your score down by area.
- Built for an open-book exam. A formula and method sheet, statistical tables computed from scratch and a calculator guide: the desk references you can bring, and practice in using them fast.
- Every calculation worked. Weibull, exponential, system models, availability, confidence bounds, test planning and acceleration models, recomputed in code.
- Methods, not just formulas. FMEA and action priority, fault trees, reliability growth, RCM and FRACAS explained with what a reliability engineer actually decides.
- Every option explained. Why the right answer is right and why each other option is wrong, for every one of the 900.
