“I wanted to stay in the trade, but I knew I could not keep doing the physical side of it forever. Assessing gave me a way to use everything I had learned without being on the tools all day.”
Terry Stone
“I had years of experience and I wanted that experience to count for more. Becoming an assessor meant I could support the next generation, work more structured hours, and build a career with more longevity.”
Liam Searle



To become a gas and plumbing assessor, the recognised route is the Level 3 Certificate in Assessing Vocational Achievement (CAVA). This qualification is designed for practitioners who assess using a full range of methods, including workplace assessment and vocationally related assessment.
The qualification covers how to plan assessments, observe performance, ask effective questions, judge evidence, provide feedback, and make fair, valid, and reliable assessment decisions. It is the standard qualification used across vocational education and training in the UK. National Careers and City & Guilds both identify it as the route used for assessing in workplaces and outside the workplace.

This course is designed for experienced dental professionals who want to progress their career without leaving the industry.
It is particularly suited to dental nurses, hygienists, technicians, or those already supporting trainees within a practice. It is also ideal for those looking to reduce clinical hours or move into a more flexible role.
Many learners come to us at a point where they are experienced in their role but unsure what the next step looks like. Assessing provides a structured and recognised pathway forward.
As a dental assessor, you will typically assess learners working towards dental nurse qualifications and apprenticeship standards. This involves evaluating competence in areas such as infection control, chairside support, patient care, and clinical procedures.
Your ability to assess is based on your own occupational competence. This means you assess within the areas you have experience in, ensuring your decisions are valid and aligned with industry expectations.
For example, a learner with experience in orthodontics may assess within that specialist area, while another may focus on general dental nursing apprenticeships.
Once qualified, you can work as a dental assessor across a range of settings, including training providers, colleges, and apprenticeship programmes.
Many learners combine assessing with part-time clinical work, while others transition fully into education roles.
For example, one of our learners now works entirely within a training provider, assessing apprentices and supporting course delivery. Another combines two days of clinical work with three days of assessing, creating a balanced and flexible career.
There are also progression opportunities into teaching, internal quality assurance, and wider training management roles.
Becoming an assessor often leads to further opportunities within education and training.
Some learners progress into teaching by completing the Level 3 Award in Education and Training (AET), allowing them to deliver classroom-based learning alongside assessing.
Others move into Internal Quality Assurance (IQA), where they oversee assessment decisions and ensure consistency across assessors.
One of our learners, Mark, progressed from dental nurse to assessor and then into an IQA role within a training provider. He now manages quality processes and supports a team of assessors, demonstrating the long-term progression available.
If you want to teach as well as assess, the usual next step is the Level 3 Award in Education and Training (AET). The City & Guilds handbook for the qualification explains that it is assessed through assignments and observation of teaching or training, and it is intended for those progressing into teaching or training in the further education and skills sector.
This means the route is often very clear. You start with assessing through CAVA, then add teaching through AET, and later move into Internal Quality Assurance if you want to oversee other assessors and manage quality across programmes.
That combination is powerful because it allows you to assess competence on-site, deliver underpinning knowledge in classrooms or workshops, and eventually progress into quality assurance or training management roles.
To assess gas and plumbing learners properly, you need more than just an assessor award. You also need to be occupationally competent in the area you are assessing.
For plumbing, that usually means a relevant Level 3 plumbing qualification and substantial hands-on industry experience. The current plumbing and domestic heating technician standard requires a Level 3 plumbing and domestic heating qualification before end-point assessment.
For gas, occupational competence is even more important because of the safety-critical nature of the work. Gas Safe says applicants for registration must hold recognised qualifications for the gas work categories they undertake, and the registration policy sets out the rules around entering and remaining on the register. Gas Safe also notes that qualified gas engineers must prove competence in their gas work areas through ACS assessment every five years to continue registration.
That means that if you are assessing gas learners, training providers and awarding organisations will normally expect you to have relevant gas qualifications, current or recent industry competence, and where appropriate the relevant ACS and Gas Safe credentials for the work area involved. That is what gives credibility to your assessment decisions. This last point is an inference drawn from the registration and qualification rules plus standard vocational assessment practice.
As a bare minimum you will need the Level 3 Certificate in Assessing Vocational Achievement. If you are also looking to teach a variety of other related qualifications such as health and safety then we also recommend combining it with the Level 3 Award in Education and Training AET).
If you also want to deliver training to staff in gas and plumbing, the recognised starting point is the Level 3 Award in Education and Training (AET). The AET is the entry teaching qualification for training and teaching adults in the UK. View the Level 3 Award in Education and Training (AET) here.
A Level 5 teaching qualification is useful for delivering regulated training within the gas and plumbing industry.
You’ll complete Ofqual-regulated teaching and assessing qualifications that are recognised and will qualify you as a Gas and or Plumbing Assessor within the UK and abroad. These qualifications can also be used to teach and assess in other sectors, as long as you have the relevant industry experience.





Self-Study of approximately 200 hours, again, at your own pace.
Our group courses can be delivered in-house at your offices or at a suitable venue. Group training can often work out more cost effective if you have several members of staff you would like to be trained at any one time.
If you also want to deliver training to staff in Gas and Plumbing (not just assess competence), start with the Level 3 Award in Education and Training (AET). It’s the recognised entry teaching qualification for training and teaching adults in the UK.
If you are assessing gas-related competence, providers will usually expect you to hold the relevant gas qualifications and demonstrate current or recent occupational competence. Gas Safe states that anyone applying for registration must hold recognised qualifications for the categories of gas work they carry out, and engineers must continue to prove competence through ACS reassessment.
Yes. The Level 3 Certificate in Assessing Vocational Achievement is the recognised qualification for practitioners assessing across workplace and vocationally related settings.
Yes, but only within the areas where you are occupationally competent. If you have competence in both plumbing and gas, you may assess across both. If your competence is only in one area, you should stay within that area.
For plumbing, learners are often on the Level 3 plumbing and domestic heating route or the related apprenticeship standard. For gas pathways, learners may also need the relevant gas qualifications depending on the route they are following.
Yes. Teaching and assessing are separate functions. You do not need teaching experience to complete CAVA, although adding AET later can broaden the roles you can do.
Not automatically. CAVA qualifies you to assess. If you want to teach, the normal route is to add the Level 3 Award in Education and Training.
Yes. Many learners complete the qualification while still working in the trade and then transition gradually into assessor work.
That depends on how quickly you can complete the assessment activity and gather evidence, but many learners work through it alongside their job rather than stepping away from employment.
Typical next steps include apprenticeship assessor, vocational assessor, plumbing trainer, gas trainer within your competence area, and later IQA or quality roles.
For many experienced engineers and plumbers, yes. It offers a way to use hard-earned trade experience in a less physically demanding and often more structured role.
Earnings vary depending on how you work. Some assessors work part-time alongside clinical roles, while others work with multiple training providers. This flexibility allows you to increase your income while reducing clinical hours.
You will receive full tutor support, guidance on building your portfolio, and help identifying learners to assess. The course is structured to ensure you can complete it alongside your current role.
After qualifying, you can work with training providers, colleges, and apprenticeship programmes. You can also progress into teaching by completing the AET qualification or move into Internal Quality Assurance (IQA) roles.
If you later manage assessor standards within your organisation, you may progress to the Level 4 Award in the Internal Quality Assurance of Assessment Processes and Practice (IQA). This qualification allows you to internally verify assessment decisions and maintain quality assurance systems.
