How to prepare for the electrical EPA

The end-point assessment for the electrician apprenticeship (ST0152, plan v1.2) has three parts, all pass or fail. Two of them you sit, one your employer confirms. Here is how to get ready for each, and what has to be in place before gateway.

The short answer

How do I prepare for the electrical apprenticeship EPA?

Prepare for the two parts you sit. For the AM2S practical, rehearse safe isolation, a full installation, testing and certification and fault finding against the clock. For the 45-question online test, practise finding answers in BS 7671, GN3 and the On-Site Guide, because the books are provided. Make sure your employer’s behaviours declaration and the gateway checklist are signed.

Key takeaways

  1. 01You sit two parts, the AM2S practical and the online knowledge test. The third, your behaviours, is your employer’s signed declaration at gateway.
  2. 02The AM2S is 17 hours over up to 3 working days. Practise each component at its real time limit.
  3. 03The knowledge test is open book with the books provided, so practise looking things up quickly rather than memorising.
  4. 04Every part is pass or fail, and NET sets the pass mark for the knowledge test.
  5. 05There is nothing to prepare for an interview, a professional discussion or a portfolio review: v1.2 has none of them.

01 · Apprentice Guide

Before gateway

Your employer and training provider decide when you go through gateway. Check that these are done, because without them you cannot be put forward:

  • Your Level 3 electrotechnical qualification is complete.
  • English and maths meet the apprenticeship funding rules.
  • The Readiness for Assessment checklist is signed by you, your employer and your training provider.
  • Your employer has signed the declaration that you have shown all the behaviours in the standard.

The behaviours declaration is one of the three parts of the end-point assessment, so talk to your employer about it early rather than at the last minute.

Preparing for the AM2S practical

The practical is 17 hours over no more than 3 working days. Practise each component on its own and at its real time limit:

  • Planning, safe isolation and risk assessment (1 hour): run the full safe isolation procedure until you do it in the right order without thinking, and write a risk assessment for an unfamiliar job.
  • Installation and maintenance (10½ hours): build complete circuits in different wiring systems, neatly and to the drawing, and keep an eye on the time at each stage.
  • Testing and the certificate (3½ hours): do the full test sequence and fill in the certificate and schedule of test results as you go.
  • Fault finding and reporting (2 hours): find faults logically from the symptoms and write down what you found and how you would put it right.

The AM2 assessment preparation guide, the AM2 exam tips and the AM2 simulator guide go through each component in detail.

03 · Apprentice Guide

Preparing for the online knowledge test

The test is 45 multiple-choice questions in 90 minutes, two minutes a question. NET provides BS 7671, IET Guidance Note 3, the On-Site Guide and the Electrician’s Guide to the Building Regulations on the day; you cannot bring your own. NET sets the pass mark.

  • Learn where things are: the Chapter 41 maximum Zs tables, Appendix 4 for cables, the GN3 test procedures and the On-Site Guide tables.
  • Do timed mock tests at two minutes a question, so you know when to move on.
  • When you look something up in a mock, note which book and which section it was in. That is the skill the test rewards.

04 · Apprentice Guide

Your behaviours

Nothing is assessed on the day for behaviours. Your employer confirms them by signing a declaration at gateway that you have shown all the behaviours in the ST0152 standard during your apprenticeship. Read the behaviours in the standard with your employer well before gateway. The best preparation is the way you work across the whole apprenticeship.

What you do not need to prepare

Plan v1.2 has no interview, no professional discussion and no portfolio review. If you are using older revision material that tells you to prepare a portfolio presentation or practise discussion questions for the EPA, it is describing something else. Keep your portfolio for your Level 3 qualification, but you will not be questioned on it at the end-point.

06 · Apprentice Guide

If a part does not go to plan

Every part is pass or fail, and you need all three. If you fail one, you only redo that part. Your employer decides whether you re-sit it with no more training or re-take it after more training, usually within 3 months. It must be done again within 6 months, or the whole end-point assessment has to be taken again.

One App for Everything!

Elec-Mate is my go to app for business and electrical work. It's feature rich without feeling cluttered. A true all in one app for quotes, certs, calculations, RAMS, EICRs, and more. I use it every day without fail, and it makes my workflow much smoother since I'm not jumping between apps anymore. The price-to-feature ratio is excellent. Any issues I've had, the developer responds within the hour and usually fixes them the same day. 100% recommend.
