The first thing you need to work out is what are the Association's objectives. If the main objective is to create an Association where only the top tier tilers can join, then you need to figure out how to vet applicants objectively. I think you'll find this will be the hardest thing to do. The risk you run with this sort of organisation is that it can very quickly become an "Old Boys Club", where existing members say: "Sorry you're not good enough." and potential members can look at it and say: "Who are you to tell me if I'm good enough?" and don't bother even applying. The other downside is that to do ongoing audits of members could be prohibitively expensive. My personal opinion is that an Industry Association set up for that purpose is fundamentally flawed and it will probably only ever attract a small number of members. Option number 2 is that the Association's main objective is to improve the industry by developing training programs and developing best practice guidelines. In this case, membership needs to be open to anyone who is working in the industry. What you can do then is to put an "Accreditation System" in place, which separates Members from "Accredited Members". There are a number of ways you can do this and we are currently working with TAFE schools and adhesive and product manufacturers on the best way to set this up and facilitate the training. Incidentally, the support from TAFE has been incredibly good. The national body looking after building industry training packages has also been very supportive of this system. I hate to say it, but I think the Americans have it pretty much nailed it and the AMTA is looking into setting up a similar system. The Americans have set up a Ceramic Tile Education Foundation and using funding from that, the NTCA and the TCNA have set up a Certified Tile Installer program. Testing includes a 155 question Technical Proficiency Exam and also a hands on test to gain initial certification. From what I hear, more than 500 tilers have already done this training.
