I don't know where Ross is, but in Scotland you need to show resent training when doing EICR with rented properties and some courses are designed for Electricians to either show resent training or to train in some special field. I have done many courses, 17th Edition, PAT testing, Insulation testing, Cherry picker operating, and many others, which were never designed as a stand alone course, but where designed to show some special aspect of that field of electrical work.
So assuming you are already an industrial electrician taking a course to show you the special aspects of Domestic work where you can drill holes in a beam, how to hide cables in walls, heights of sockets, where you can place a consumer unit etc. In industrial electrics electricians and be quite remote from the electrical engineers who design the installation and often require different skills like dressing cables, and how to fit a gland without marking it, or how to read a PLC controlling a machine.
There are also courses for allied trades, where a plumber may learn some basic electrics or an electrician may learn some basic plumbing. Believe me I have tried repairing a lead pipe and wiping the joint and it does take skill. With every trade there are different areas, I heard of some one being a pipe fitter and I imagined some one threading a bit of pipe and bending it, then I worked alongside pipe fitters and realised I had got it all wrong. Getting a thick wall 32" pipe ground so when the crane lifts it into position it fits first time is a real skill. This is also the problem with the electrical trade you watch an electrician doing one aspect and think is that all there is to it that's easy, but every trade has a whole range of skills.
As far as I can see from the link the course does what I did after completing my apprenticeship at night class. It gives you the bits of paper you need to show employers that you have skills in the areas they require. Days 11 - 18 I did as a night class, it took 18 weeks at 3 hours a week. A full time course is 16 hours a week you are expected to do home work, so my 18 weeks at night class should take around 4 days where this course takes 7 days so it will likely include a little more than I did, but not much more.
Today the apprenticeship has changed, in my day we had day release over 4 years, plus night classes, there was a problem with day release in that you started the apprenticeship with little or no knowledge so you were little more than a mate in the early years, by time you were 18 you were starting to understand some of the work, but today children don't start until they are 18 so some method of fast track is required to get them qualified before they reach an age where they are married with kids. So they now do block release. So 18 weeks solid training then 18 weeks working and so on, which reduces the apprenticeship to something like 2 years instead of the 7 years my dad did or 4 years I did it has to change because the government will not allow them to start at 14 years old as in my dads day, or 16 years old in my day.
The course you have looked at is one of these block release courses it is designed so that you work some where to practice what has been taught with some supervision it is not designed so once complete you start work as a sole trader. It could however work very well if you have an electrician that you can work with who can answer the questions which always arise in a new trade, and can correct you if you have miss understood an instruction. He will also guide you as to rule of thumb methods. For example one role of twin and earth for a ring main.
So to answer the question, it allows you to work more like a third year apprentice rather than a first year apprentice when working with other electricians.
