Hi Ainsley and welcome to the forum. I did such a course, but it depends where you do it and what you put into it.i had completed a plastering course and then a year and half later went back for the tiling course, I'd had some experience before, tiling and also worked on many old houses. So had some knowledge. What I would say is you won't know everything and you'll be surprised at what's involved in tiling. There's a ton of info and loads help on here and I think you will learn a lot from checking the different threads out. I'd check reviews of the place you want to train at first as it's a load of money to waste.good luck. D
