The 'blame' is not so much with the Lecturers, but the nature of the industry itself. There is an intransigency, zones of demarcation and jobs worth mentality that pervades still. - Lets not bring in the plumbers, Lol.....
There is not much wrong either with the quality of the student, only that they need to learn about the dangers of electricity, a correct approach to wiring, sizing and fixing. These are not difficult skills to learn but takes about five or so years to instill as so that they become second nature and electrical knowledge ferments into common sense. This approach often means that the 'qualified' installation electrician only remembers and/or understands the techniques that have been shown him/her by their employer and/or teacher. Add another 10 years of experience and the learning process spreads out to understand how things actually work.
A very good reason why anything more than basic inspection and testing of ones own work should not be attempted by a newly qualified electrician.
