Verification of Competency (VOC) is a formal process that confirms a worker can perform a specific task safely and correctly under real or simulated working conditions. It goes beyond training records and quiz scores to assess actual, demonstrated capability — answering the question "Can they do it?" rather than "Did they learn about it?"
The concept originated in high-risk industries. In Australian mining and construction, VOC has been a regulatory requirement for years. If you operate a forklift, work at heights, or handle hazardous materials, your employer must periodically verify — through direct observation — that you can still perform the task safely. Not retrain you. Verify you.
Manufacturing is now catching up. And for good reason.
Why VOC Is Gaining Traction in Manufacturing
Three forces are pushing manufacturing toward formal competency verification:
Regulatory pressure. The standards that govern manufacturing quality have always required competency — but auditors are interpreting those requirements more strictly than ever.
- AS9100 (aerospace) requires organizations to "evaluate the effectiveness" of actions taken to ensure competency. A training completion record doesn't demonstrate effectiveness.
- FDA 21 CFR Part 820 (medical devices) requires that personnel be "qualified" through education, training, and experience — and that this qualification be documented with evidence.
- IATF 16949 (automotive) requires demonstration that workers understand the importance of their activities and can perform them correctly.
- FDA 21 CFR Part 11 adds requirements for electronic records and signatures, meaning your competency evidence needs to be tamper-proof and traceable.
Complexity growth. Products are more complex. Processes change faster. The shelf life of a competency assessment is shrinking. Annual recertification made sense when processes were stable for years. It doesn't work when you're introducing engineering changes monthly.
Workforce volatility. High turnover, cross-training programs, and temp workers mean you're constantly onboarding people onto critical processes. "They were trained" isn't enough when someone learned a process three jobs ago.
What a VOC Process Looks Like
A proper VOC assessment has four components:
- Defined criteria. What does "competent" look like for this specific task? Not general knowledge — specific, observable behaviors and outcomes. "Applies torque to spec using calibrated wrench" is a criterion. "Understands torque" is not.
- Observed performance. The worker performs the task — either in production or in a controlled assessment — while being observed. This is the core of VOC: you watch them do it.
- Evaluation against criteria. The observer (or system) compares what they saw against the defined criteria. Pass/fail or proficiency rating.
- Documented evidence. The assessment is recorded with enough detail to satisfy an auditor. Who was assessed, on what task, against which criteria, what was the result, and when did it happen.
The challenge has always been step 2. Observation requires a qualified assessor to be physically present, watching one person at a time. In mining, where crews are small and risks are extreme, this is manageable. In manufacturing, where you might have 300 operators across three shifts running 50 different processes, it's a logistics nightmare.
Scaling VOC with Technology
This is where the model is shifting. Instead of requiring a human assessor for every verification, companies are using video and AI to scale the observation step.
skillia.AI was purpose-built for this. Workers record themselves performing a procedure using a phone or tablet. The AI evaluates the recording against the defined criteria — the same criteria a human assessor would use — and generates a documented competency record with video evidence attached.
It's still VOC. The criteria are still defined by subject matter experts. The performance is still real. The evaluation is still rigorous. What changes is that you don't need to schedule an assessor, coordinate shifts, or hope someone was watching closely enough to give an honest assessment.
The result: VOC that scales to every operator, every process, every shift — with evidence that holds up under audit.
FAQ
How often should VOC assessments be conducted?
It depends on risk and regulatory requirements. High-risk tasks may require quarterly or semi-annual VOC. At minimum, reassess after onboarding, process changes, extended absence from a task, or following a safety incident.
Is VOC the same as a practical assessment?
VOC is a type of practical assessment, but it specifically focuses on verifying continued competency — not just initial qualification. It's typically applied to workers who have already been trained and previously qualified.
What industries require Verification of Competency?
VOC is legally required in Australian mining, construction, and oil & gas. It's increasingly expected (though not always named "VOC") in aerospace (AS9100), medical devices (FDA), automotive (IATF 16949), and pharmaceutical manufacturing.
