PAT Testing Mock Tests

PAT testing deems whether electrical appliances are safe for use, and if there are intended function is operating correctly. Given the exponential growth of electrical usage in both public and private sectors, PAT testing is a regular duty conducted by electricians.

Businesses rely on this equipment to be able to maintain industry. Therefore, it is in their best interests to keep it routinely serviced. Moreover, employers have a responsibility to ensure staff remain safe in their respective workplaces, and PAT testing offers protection against electrical hazards. Although there is no legislative guidance on PAT testing, it’s well-established that assessments should ideally be conducted by fully-qualified electricians. Furthermore, most businesses will establish annual testing practices, as this meets industry-recognised guidance on frequency.

In order to gain the necessary accreditation to perform PAT testing, individuals must sit an appropriate examination. This article intends to provide an overview of what this assessment will look like, before incorporating some ‘real-world’ exam questions.

Learning Approach

Prior to conducting this test, candidates will undertake an appropriate learning programme. This will help suitably prepare them to have the best possible chance of passing their assessment.

However, individuals should not undertake courses with the sole purpose of navigating their final exam. If PAT testing information is simply committed to memory, and studied in independence from its governing principles and theories, then the likelihood is that the assessment will feel more challenging than it needs to. The best candidates absorb knowledge whilst considering its practical application in the field. This provides a more holistic view on PAT testing processes, and better places them to tackle the exam. It will also provide a better platform for success when exercising PAT testing in the industry.

Course Information

These may be conducted as isolated courses away from formal training programmes, or integrated into an apprenticeship or diploma. Future course content should be checked prior to organising a PAT testing qualification, as this may be already covered within long-term training plans. A variety of learning providers offer courses in PAT testing, with this certification awarded by several different industry bodies. For the purposes of this article, we’ll focus on the City and Guilds 2377-77 EET/PAT Testing course.

The ‘EET’ element stands for ‘Electrical Equipment Testing’ This part of the qualification which has significantly grown in stature in recent times. Additional focus on EET elements has developed due to technological advancement and increasing electronic device usage. As a result, the scope of equipment testing has substantially increased. This means that the PAT testing discipline no longer independently addresses all industry requirements. Nevertheless, PAT testing will most likely always remain a salient part of electrotechnical practice.

For reference, the City and Guilds (C&G) are an industry-recognised, leading skills provider, who offer numerous qualifications schemes across a range of sectors. Therefore, delegates can trust course content will prepare them thoroughly for PAT testing activity.

The Assessment

At the conclusion of the course, an assessment will need to passed. This serves to demonstrate that the individual has the competency to conduct PAT testing in ‘real-world’ scenarios. This will be a reflective examination based on the content learned throughout the course. Most learning providers will offer two course duration options, which will be based on experience and current capability level. For those who have already accumulated some industry knowledge, it’s advised that they undertake the shorter programme length. This usually lasts approximately two days. Candidates who are relative novices in the electrotechnical sector, should attend the more extensive training sessions. In doing so, they will most likely receive an additional full day of study. This will provide the appropriate foundation knowledge, and allow individuals to tackle more complex theory later on in the course.

Assessment Structure

The assessment itself consists of 50 multiple-choice questions, and lasts 1 hour and 45 minutes. This facilitates a response time of just over two minutes per question. The exam is ‘open-book,’ which means approved literature can be taken into the examination hall (or used remotely in virtual testing).  For this exam, students are permitted to use the IET: Code of Practice- In-service Inspection and Testing of Electrical Equipment- 5th Edition. This is an article which will be consistently referred to during the C&G 2377-77 course. To pass this assessment, candidates must register a score of at least 80%.

Top Tips

In terms of testing approach, it’s worth considering the following ‘top tips’ to ensure you’re appropriately prepared for the exam:

  • Ensure that you read through each question thoroughly. Assessments can be highly-pressurised environments, often leading to information or key wording being missed in questions. Make sure you don’t succumb to this common error.
  • The test will come with in-built flagging software. Therefore, if you’re unsure of an answer, you can simply ‘mark’ it, and re-visit it later on in the exam. Deploy this wisely, as it may mean you could avoid wasting too much time early on in the assessment. Flag when its appropriate to, otherwise this could lead to increased nervousness around completion timing.
  • Don’t panic if you originally feel compelled to guess an answer. You can also change responses later, with the help of the same flagging tool articulated above.
  • Do not spend unnecessary time reviewing the Code of Practice document. If you’re fairly confident of your answer, press on. Some candidates will constantly check the note to assure themselves they’ve answered correctly. This could waste valuable time.
  • Remember, even though they’re multiple-choice questions, answer’s still need to be applied with considerable care and patience. Questions will often challenge you to work out involved sequences. Each option will need to be worked through to its conclusion, before allowing you to answer through a process of elimination.
  • Ensure every question has been answered.
  • Lastly, try not to finish the exam before the allocated time has elapsed. If all questions have been offered a response, and flagged questions have been addressed, then double and triple-check answers given. You never know when you may have made a silly mistake! This would also be a more suitable time to compare responses to the information contained in the Code of Practice note.

Mock Tests

The following section offers some examples of questions you may come across in the assessment. These have been extracted from a combination of real, historical test papers, so don’t be surprised if these re-appear in your actual assessment. The more ‘mock’ test papers you complete, the higher the likelihood is that you’ll pass your final examination.
