How do you calculate a Training Gap Score?

Multiply the three 1-to-10 sub-scores: severity x occurrence x detection. With severity 6, occurrence 4 and detection 3 the score works out to about 4.55 on the calculator's normalized scale, letting you rank it against other gaps scored the same way.

What is a good Training Gap Score?

Lower is better because it means the gap is low-consequence, rarely hit, and easy to catch. There is no universal pass line; set an internal threshold (for example, anything above your median gap score gets a scheduled retraining plan) and review the top decile monthly.

What scale should I use for severity, occurrence and detection?

Use a consistent 1-to-10 anchored scale across every gap. Severity 10 might be an injury or customer escape; occurrence 10 means the operator faces the task every shift; detection 10 means no downstream check would catch the error.

Training Gap Score vs a simple skills matrix — which should I use?

A skills matrix tells you who can do what; the Training Gap Score tells you which of those missing cells actually matters. Use the matrix to find gaps, then score the high-impact ones to prioritize.

Why is a high detection score bad here?

In FMEA convention a high detection number means the gap is hard to detect before it causes damage, which raises risk. If you have strong in-line checks that would catch an under-trained operator's mistake, score detection low.

How often should we re-score training gaps?

Re-score after any process change, new product launch, staffing turnover, or quality escape, and at least quarterly. Occurrence in particular shifts as people rotate roles.

Training, Certification & Skills Compliance calculator

Training Gap Score Calculator

The Training Gap Score is an FMEA-style risk priority number applied to workforce competency. Instead of scoring a failure mode on a part, you score a missing or weak skill: how bad the outcome is if the gap causes an error, how often an under-trained operator will actually encounter the task, and how likely your controls are to catch the mistake before it leaves the cell. Training managers, quality engineers and shift leads use it to rank a backlog of skill gaps so limited classroom and OJT hours go to the highest-risk ones first. It turns a subjective 'we should probably retrain welding' into a defensible, comparable number.

What this calculator does

Estimate training gap 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 training gap 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 for a single training gap to produce one comparable risk priority number.

Formula used

Training gap risk score = training gap severity score × training gap occurrence score × training gap detection score
Use the same scoring scale across comparable training gap risks.

Inputs explained

Severity if the skill gap causes a defect or safety event:
Likelihood the untrained worker actually hits the gap:
Ability to catch the gap before it reaches product:

How to use the result

Use it when you have more identified skill gaps than time to close them and need to sequence retraining by real operational risk.
The multiplicative RPN treats a 6x4x3 the same as a 3x4x6, so a catastrophic-severity gap can be masked by low occurrence — always review high-severity items regardless of total score.

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).
