To be honest with you, I'm not too familiar with these studies. I'm told there are some out there in terms of examining the different practices. There's a fair amount of expertise within the CCDA in terms of various apprenticeship programs.
We're certainly interested in what's going on in the U.S. right now. This is an area where there is a vast pool of available workers in the trades. One of the important aspects is bringing workers from abroad as well. I'm stretching your question to cover the issue of foreign workers. It is certainly the aspect of assessing those foreign workers, not necessarily in the traditional way of a Q and A assessment or test, but using multiple assessment instruments to do that work.
