I will speak for all the training centres here, everyone is different and have different abilities to learn, some pick things up quickly others dont, depends on how practical you are in the first place, doesnt mean you have to be a practical tiler just handy at DIY, Once you leave a course it is really down to yourself weather you have the confidence to go out self employed, some people will never make that jump no matter how good they are as it can be a scarey place to be without the security of a regular wage, on the other hand there are those that take the plunge and have the drive to succeed and go and find the work and learn more along the way, any training centre can only guide you on what to expect on a real paid job, it is different when you get out there but like any new job that you take on, it will take you time to learn how to do it quicker, we have had people that have come with no experience of putting a
tile on and go out straight away and do very well, other go out there and dont do so well, everyone does the same course and learns the same skills which comes back to its down to the individual on how much you want it to work, if you still are doing your old job and tiling on a weekend then you will never develop your full potential as you havent got the time to promote , market yourself the correct way.
You will only get out of life what you put into it, there is no easy way of making money, you HAVE to go out and earn it, unfortunatly
Hope this is of some help
