Maintenance, Reliability and Failure Analysis Certification

The Maintenance, Reliability and Failure Analysis Certification is a free intermediate-level, 20-minute skill test from Science of Apps. It tests maintenance and reliability engineering for technicians, planners and reliability engineers — maintenance strategies (reactive, preventive, predictive and reliability-centered), core reliability metrics (reliability, availability, MTBF, MTTR and the bathtub curve), failure and root-cause analysis (RCA, 5 Whys, fishbone and FMEA), and reliability programs and condition monitoring (CMMS, vibration, thermography and oil analysis). Written to SMRP, SAE JA1011 (RCM), FMEA and ASQ sources for 2026. Score 70% or more on its 20 questions to earn a verifiable Maintenance and Reliability Proficiency certificate (SOA-MRFA). Every question is based on published standards and research — including SMRP Body of Knowledge (five pillars) and CMRP certification (Society for Maintenance & Reliability Professionals), SAE JA1011 Evaluation Criteria for Reliability-Centered Maintenance (RCM) Processes (SAE International), ISO 18436-2 Condition monitoring personnel qualification – Vibration condition monitoring and diagnostics (ISO) — and each answer is explained with its source.

Science of Apps offers a free Maintenance, Reliability and Failure Analysis Certification, updated for 2026 and 2027. It measures maintenance strategies, reliability concepts, failure and root-cause analysis and programs and condition monitoring and gives instant results with a shareable certificate.

Read the four skill areas on this page, then take the 20-minute test online — no fee, course or sign-up. You see every answer explained when you finish. Score 70% or more and you get a Maintenance and Reliability Proficiency certificate straight away, on screen, as a PDF and by email, with a credential ID anyone can verify.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: SMRP Body of Knowledge (five pillars) and CMRP certification (Society for Maintenance & Reliability Professionals); SAE JA1011 Evaluation Criteria for Reliability-Centered Maintenance (RCM) Processes (SAE International); ISO 18436-2 Condition monitoring personnel qualification – Vibration condition monitoring and diagnostics (ISO); Root cause analysis tools and resources (ASQ); AIAG core tools: APQP, PPAP, FMEA, MSA and SPC manuals (Automotive Industry Action Group); Fishbone (Ishikawa) diagram (ASQ). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Maintenance Strategies (Reactive, Preventive and Predictive); Reliability Concepts (Metrics, Availability and Curves); Failure and Root-Cause Analysis (RCA, FMEA and Tools); Programs and Condition Monitoring (CMMS, Monitoring and KPIs). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

Maintenance technician or planner, Reliability engineer, Plant or facilities manager, Asset management professional and CMRP candidate. It suits anyone who wants a quick, verifiable way to show Maintenance and Reliability knowledge in 2026 and 2027, from students and career switchers to experienced professionals.

RCM is a structured method for deciding the maintenance each asset needs to meet its function in its operating context. SAE JA1011 sets out the criteria an RCM process must satisfy, such as identifying functions, failures, failure modes and effects, and selecting appropriate, worthwhile tasks.

Preventive maintenance is done on a fixed schedule (time or usage) regardless of condition. Predictive maintenance (PdM) uses condition monitoring — vibration, thermography, oil analysis — to act only when data shows a developing fault, so work is based on actual equipment condition.

Yes. The test is online, in English and free everywhere — people take it from India, the US, the UK, Europe, Africa, Latin America and Asia-Pacific. Your certificate is dated with your own local date and can be verified from anywhere at scienceofapps.com/certification/verify/.

20 questions — 5 from each of 4 skill areas — with a 20-minute limit. You need 70% (14 of 20) to pass and 90% for distinction.

We rate it Intermediate: assumes hands-on experience in the role. It has 20 scenario questions — 5 from each of 4 skill areas — and a 20-minute limit. You need 70% (14 of 20) to pass and 90% for distinction.

Nothing. There is no fee to take a test, to receive the certificate, to have it emailed or to verify it, and no sign-up.

On our server, not in your browser. The answers never reach the page until you submit, so a certificate can only be earned by passing. Each certificate gets a unique credential ID stored by Science of Apps.

You see your score for each area and every question with the correct answer and why, with the published source behind it. You can retake after 30 minutes, and the retake draws questions you haven't seen yet.

No. Every certificate is dated, so it always shows when you passed. Retake a test any time for a newer date or a higher score.

Yes. After you pass, Add to LinkedIn opens the Licenses & certifications form with the certificate name, Science of Apps as the issuer, the issue date, your credential ID and the verification link filled in. You can also download it as a PDF or PNG, and it's emailed to you as a PDF.

Every certificate has a credential ID and a QR code. Scanning it, or entering the ID at scienceofapps.com/certification/verify/, shows the holder's name, the certification, the score and the issue date from our records.

No. They are Science of Apps' own assessments of applied skill. They aren't issued by a university or standards body, and they work best alongside a portfolio that shows the skills in real work.
