Hi phil, here is my opinion from an tiler with 7 years experience, I would say I'm on the same boat of many other guys on here, I have covered pretty much anything domestic from splash backs to 100m2 floors in a variety of materials not to mention a few wet rooms too. I understand setting the plane of the tiles, where it's essential to make tiles 100% plumb and where not. Given the experience I have compared to let's say, someone with a years experience then I wonder how you can structure your course. I remember when I trained at nett I knew that there was only maybe another one guy on the course I could see had the ability to be a tiler and because the course was geared to give everyone a chance then at times I thought it could be moving faster.. I think if you start your course you need to be carefully what you say your gonna deliver. There are some guys on the forum who may turn up and will only slow the others down. ( I hope I don't sound arrogant by saying that) and I don't mean to offend anyone else with limited experience - if you remain dedicated and passionate about tiling then I'm sure you will get their but learn to walk before you run.
As for location then it's very obvious it should be in Scotland... (Joke), ... It must be somewhere central IMO, (Manchester - Newcastle)
Or...
Maybe this course would not need to be necessarily need to be hands on? We have all worked with tiles, you either lift them, cut them or stick them, so what are we learning? The set out, the procedure on which bit to do first, the methods,... Could this not be done using online videos where a student would pay a fee then get access?... Just an idea for you phil. (Hope I don't sound disrespectful to your craft by suggesting this.)
