How do you calculate expired certification risk?

Multiply the severity, occurrence, and detection scores together. On the standard scale, 6 × 4 × 3 gives an RPN in the region of the 4.55 shown here after the tool's scaling, which you then rank against other lapsed certs.

What is a good expired certification risk score?

There is no universal threshold, but many quality systems flag any RPN in the top decile or any item with a severity of 9-10 regardless of RPN. Set an action line and treat everything above it as mandatory before work resumes.

What do severity, occurrence, and detection mean here?

Severity is how bad the outcome is if a lapsed-cert worker causes an incident; occurrence is how likely a certification slips out of date undetected; detection is how well your tracking catches the lapse before work proceeds — higher detection score means worse (harder to catch).

RPN vs a simple overdue count — why score at all?

An overdue count treats an expired crane cert the same as an expired refresher. RPN weights consequence and detectability so limited renewal effort goes to the credentials that can actually hurt someone or fail an audit.

Should I act on high severity even if the RPN is low?

Yes. A severity of 9-10 — a credential tied to fatality or major regulatory exposure — warrants action regardless of a low RPN driven by rare occurrence. Never let multiplication hide a life-safety item.

How do I keep scoring consistent across certifications?

Use one published scale with defined anchors for each 1-10 level and calibrate as a team. Comparing RPNs is only valid when every credential is scored on the identical rubric.

Training, Certification & Skills Compliance calculator

Expired Certification Risk Calculator

Expired certification risk applies FMEA-style thinking to lapsed credentials — welder qualifications, crane operator cards, forklift licenses, NDT levels, or GMP sign-offs that have quietly gone out of date. Safety and quality engineers score each lapse on severity, occurrence, and detection to produce a risk priority number (RPN) that ranks which expirations to chase first. It matters because not all lapses are equal: an expired first-aid card and an expired crane certification carry wildly different consequences, and a limited renewal budget should target the highest RPN. Scoring turns a flat list of overdue certs into a defensible remediation queue.

What this calculator does

Estimate expired certification risk for training, certification and skills compliance using production-ready inputs so teams can rank risks and decide which issue needs containment, controls, or escalation first.
Use it when expired certification risk in training, certification and skills compliance needs a defensible ranking against other training, certification and skills compliance risks for the next review.
It multiplies severity, occurrence, and detection scores into a single risk priority number for a lapsed or expiring certification.

Formula used

Expired certification risk score = expired certification risk severity score × expired certification risk occurrence score × expired certification risk detection score
Use the same scoring scale across comparable expired certification risk risks.

Inputs explained

Severity if the expired certification causes an incident:
Likelihood a certification lapses undetected:
Ability to detect the lapse before work proceeds:

How to use the result

Use it to triage a backlog of expired certifications, prioritize renewal spend, or feed a management-of-change review before letting a lapsed operator resume work.
RPN is a relative ranking, not an absolute probability — a high severity item can still be masked by a low occurrence score, so always review severity in isolation for life-safety credentials.

Current U.S. benchmarks

Manufacturing hourly earnings average $30.27 (BLS, Jun 2026), up 4.4% from a year earlier. Median machinist pay is $28.24/hr (OEWS 2025), with state medians on each state page. Manufacturers have 529k open positions nationally (BLS JOLTS).
