What is a VOC?
A Verification of Competency (VOC) is typically a combined theory and practical assessment that confirms a worker can safely and competently operate a specific item of plant or equipment, or perform a task to the required standard.
A VOC is for workers who already hold the relevant units of competency and/or high risk work licences. Rather than training a licence from scratch, it essentially “verifies” that their existing skills are current, checking them against a set competency standard, often a particular site’s requirements, so they can be cleared to operate on site.
STES RTO Assessment (VOC): what you need to know
A STES RTO VOC is a combined theory and practical assessment conducted under our own assessment standards and documentation. Because it’s delivered by STES as a Registered Training Organisation, a provider regulated and audited under national quality standards, an RTO-backed VOC carries real weight with site supervisors, contractors and HR teams. It gives employers confidence the assessment was rigorous, consistent and carried out by qualified assessors, and it’s ideal when you need a VOC that isn’t tied to a single mine or energy site’s standard.
Every STES VOC is benchmarked against the relevant unit of competency where applicable and, where possible, contextualised to your actual worksite. Our assessors are experienced, industry-qualified professionals who hold each assessment to a rigorous, consistent standard.
These VOCs suit workers who regularly apply their skills and need to demonstrate current competency without full retraining, as well as employers who need a time-efficient, cost-effective way to verify their crew before mobilising.
STES VOCs are typically valid for 12 months. We assess at our Bibra Lake facility or on-site across Western Australia, using your equipment or ours.

How our STES VOC assessments work
From first contact to receiving your competency record, here's what to expect when working with STES.
01
Enquire & book
Contact us with the equipment type and number of workers. We'll confirm availability and pricing. Short-notice bookings are available.
02
Pre-assessment check
Workers provide evidence of their HRW licence (where applicable) and any prior training. Our assessor reviews documentation before the assessment.
03
Theory & practical assessment
Each worker first completes a short theory examination to test their knowledge of the equipment and safe operating procedures. They then perform a practical assessment while our assessor observes them against a structured competency checklist, at our Bibra Lake facility or on-site.
04
Result & record
Competent workers receive a signed VOC record on the day. Records are stored in our RTO management system and can be provided on request.
About the STES assessment standard
Because VOC sits outside the VET system and its regulator ASQA, not all VOCs are created equal. As a Registered Training Organisation, STES brings the same rigour and assessment discipline to every VOC it conducts, giving your RTO-backed VOC added credibility on site.
Benchmarked to units of competency
Every STES VOC is benchmarked against the relevant unit of competency, so the assessment is meaningful and defensible.
Assessed by industry-qualified assessors
Our assessors are experienced, industry-qualified professionals who assess against a structured competency checklist for each equipment type.
Onsite where possible
Wherever access permits, we conduct assessments at your workplace using the site's own equipment, giving the most accurate picture of a worker's readiness.
Records available on request
Competency records are stored in our RTO management system and can be provided to site management, contractors or HR teams to support mobilisation and induction.
Frequently asked questions: STES VOC
What is a STES VOC?
A STES RTO VOC is a combined theory and practical assessment conducted under our own assessment standards, confirming a worker can safely and competently operate a specific item of plant or equipment. Delivered by STES as a Registered Training Organisation, an RTO-backed VOC gives site supervisors and employers added confidence in the result, and suits workers who need a VOC that is not tied to a single site standard.
Do I need an HRW licence before a STES VOC?
For equipment that requires a High Risk Work (HRW) licence, such as cranes, rigging, dogging and scaffolding, you must hold the current licence before a VOC can be issued. For plant categories like EWP (Yellow Card) and TMH, an HRW licence is not legally required.
How long is a STES VOC valid for?
STES VOCs are typically valid for 12 months. Many WA sites will not accept a competency older than 24 months, so we recommend re-assessing regularly. Always confirm the requirement with your site or contractor management.
Can STES conduct the VOC at our workplace?
Yes. We travel across Western Australia to conduct VOC assessments on your equipment. On-site assessment is preferred where possible, as it allows workers to be assessed on the actual machines they operate in their working environment.
What standard are STES VOCs assessed against?
Every STES VOC is benchmarked against the relevant unit of competency where applicable and, where possible, contextualised to your actual worksite. As a Registered Training Organisation, STES holds each assessment to a rigorous, consistent standard, carried out by experienced, industry-qualified assessors.
What happens if a worker does not pass?
The assessor will provide specific feedback on the gaps observed. The worker can undertake additional practice or training and book a re-assessment. Our goal is to ensure genuine competency, not to create unnecessary barriers to site access.
