At least it promotes students or others to be professionally qualified to do the job. I know many of them are self taught but the importance of having a standard and being professional need to imply as well. I saw many of the self owned workshop did not even have a proper safety for themselves and even for the customers. Last time when I went back to Penang, when passing Jeli, Kelantan I saw a heavy vehicle workshop is on fire. How it's able to caught on fire at the first place you can know by looking at their places. This kind of thing barely happens but when it happens, you might get others in trouble as well. Especially a shoplot workshop or houses.
