Virtual Classroom – Our hi tec virtual learning suite enables you as the trainee to experience exactly the same course and level of interaction with a trainer as though you were in the same room as them. This isn’t a slideshow-based course, it’s a real tutor, in a real room taking you through all you need to know to be successful in your City and Guilds 2391 – 52. Utilising equipment and software, the theoretical part of the course will be taught over 3 days via the internet. During this time, you will be taught the theory-based elements below, also allowing ample time for questions face to face with the tutor. The instructor will go through everything that you will be expected to know about Inspection and Testing on both new and existing installations. You will be given access to our dedicated online portal to work through sample questions in your own time until the information becomes second nature to you. Your only hardware prerequisite for this part of the course is access to the internet, whether it be on a computer or a smart device. The second stage of the course will involve you attending one of our numerous training centres around the UK, for both the practical training and the examinations over a 2.5 day period. This will be booked for a later date and one of our team will be in touch with you to arrange this. During your time at one of our centres you will be taught the inspection and testing practical elements you require on individual training rigs, with equipment and testers for each and every individual person. (Our centres are ALL Covid secure and the training bays, etc are all socially distanced). This City & Guilds qualification is aimed at practicing electricians who have not carried out inspection and testing since qualifying or who require some update of training. This qualification helps you to develop the knowledge and practical skills required to professionally install and carry out initial verification and periodic inspection and testing on electrical installations. It is expected that suitable candidates have a basic knowledge and understanding of electrical science and principles and experience of electrical installation work. This is an essential skill for any electrical installer.

This course presents an approach for dealing with security and privacy throughout the entire software development lifecycle. You will learn about vulnerabilities that undermine security, and how to identify and remediate them in your own projects.
