Learning depends on the teacher, and how its delivered, our course is certainly no way a diy course, all courses are entry into the trade even your longest course as everything you can teach in the training centre is artificial, longer courses stick more tiles on a wall, you dont actually learn that much more if any, once you know how to cut and shape, set out properly and tile walls and floors, then sort out your backgrounds, the rest you need to learn out in the real world, i usually let my feedback on here do the talking for me as i have by far the most happy people that are confident, most of which are out there in the tiling world now, Just had a young lad on doing a plumbing course, came from a year long course at college, didnt even know how to install the sanitary ware, so long courses doesnt mean that they are the best,
like i said before its down to the tutor and im in my 5th year now of personally delivering the course at my training centre, so i know how to get the best out of peolpe and my methods are extremely quick and effective.
If people are really lacking in DIY skills and have no confidence then i agree that a longer course would be better, but you should be aware that if you are that kind of person to start with, you maybe should think twice about a career in this tarde as a self employed tiler, you have to be a thinker to solve problems on your own and be very driven to do well
Ive seen loads of people spend there money on long courses and short courses just to find out that tiling isnt for them, at least with a shorter course your wouldnt waste as much if that was the case,
