What Is the NVQ?

The NVQ is a practical portfolio build which is in place to help you demonstrate your workplace competence. It can take anything from 6 months to 36 months to complete.  

Most training providers use an online file management system such as OneFile, Smart Assessor or VQManager.   

We use the OneFile management system.

Why Do I Need to Do the NVQ?

This is the part that links the theory you learnt in college or a training centre (2365-02 and 2365-03) to real work scenarios.  
 
The NVQ is designed to make sure you can work safely and efficiently and to the high professional standards required to hold an ECS JIB Gold Card
 
Also, without it you can’t become a fully qualified electrician.  
 
The biggest question the portfolio is there to help answer: 
 
Can you perform electrical work safely and consistently in real working conditions while making sure your work is aligned with national standards?

What’s Involved in the NVQ?

The 2357 NVQ is split into seven essential units. each unit needs to be passed before you can apply for your ECS JIB Gold Card
 
Please note, you will have to pass your AM2 before applying for your ECS JIB Gold Card.  

The Seven Practical Units to Success 

There are 7 Practical Units to complete: 

  • 311: Health & Safety  
  •  312: Environment  
  • 313: Work Planning  
  • 315: Installing Wiring Systems  
  • 316: Terminations  
  • 317: Testing  
  • 318: Fault Finding  

Unit 311 – Health & Safety Unit

This unit must be observed face to face on two separate occasions with a minimum of three months apart
 
Before each site assessment you will need to complete a Risk Assessment, Method Statementand a Work Programme.  
 
You will need to be doing a task working at height using access equipment, e.g. stepladders, ladders, platforms, MEWPs, or scaffolding.  
 
Also, you should be wearing the correct PPE as per your Risk Assessment/Method Statement. 
 
You will be asked questions about the task you are doing and H&S questions; your behaviour and conduct will also be observed.
During the assessment, you may also be able to show the assessor product evidence of the work you have installed. Product evidence means supporting proof of completed work, such as before, during and after photos, certificates, test results, installation records, or other documents that show the task has been completed correctly. 

Recap The three essentials: 

  • Correct PPE selection based on site-specific risk assessment

  • Safe isolation procedure demonstrated in stages

  • Controlled work areas with appropriate signage

Unit 399 – AM2

The AM2 is not delivered as a normal portfolio unit. It is a separate, externally assessed competence test that you must complete at an approved NET AM2 Centre. 

Once you have completed the seven practical units, we will support you with applying to an approved AM2 Centre to sit your AM2 assessment. This is an additional cost. 

The AM2 is a practical assessment carried out over approximately two and a half days. It is designed to test your occupational competence and includes key areas such as installation, inspection and testing, fault diagnosis, safe isolation and understanding of electrical working practices. 

You can find further information at: www.netservices.org.uk 

Once you have passed the AM2, your portfolio can then be completed and signed off by City & Guilds. When you receive your 2357-44 NVQ, you will then be able to apply to ECS for your Gold Card. 

Summary of Documentation Required to be Completed

At Elec Training this is what we expect from students: 

  • 2 Risk Assessments 
  • 2 Method Statements 
  • 2 Work Programmes 
  • 2 Electrical Installation Certificates 
  • 1 Minor Works Certificate 
  • 2 Witness Testimonies for the Inspection/Testing and completion of Electrical Installation Certificates 

Use of Photographic Evidence

One of the biggest problems we see with students every week is incorrect photographic evidence. It’s literally two ends of the scale: either 50 photos when only 3 are needed, or post-completion photos only.

If you are using photos as evidence for a task you are working on or have completed, you should provide a minimum of three photos: before, during and after. 

Example

Before 

Before image This task was to terminate a TV point using the screwed method

This task was to terminate a TV point using the screwed method. 

During

Strip back the outer sheathing, exposing the braided cable, which is to be connected to the clamp on the back of the plate.

After

Completed installation of the terminated TV point, with the plate securely fitted and the cable connection enclosed neatly behind the faceplate. 

Struggling to get site experience?

For many learners, the hardest part of the 2357 NVQ is getting access to genuine electrical site work where the evidence can actually be collected. 

To complete the NVQ, you need real workplace evidence across the seven practical units. That means you need to be working on suitable electrical tasks, taking before, during and after photos, collecting witness testimony, completing site paperwork, and being observed by an assessor where required. 

Elec Training supports learners with this through our electrical paid work placement route. Our recruitment team, works with contractors to help suitable learners access real site opportunities and start building the evidence needed for their NVQ portfolio. 

This support is a major part of the Elec Training route. We understand that adult learners and career changers often do not already have electrical contacts, which can make the NVQ feel difficult to start. Our placement process is designed to help our enrolled students bridge that gap by helping learners become more employable, more prepared for site, and better positioned to complete their NVQ evidence.
