In our case the school board doesn't have the resources to WISC test every kid (or even a tiny percentage of kids) so CCAT (Canadian CogAT) it is. They don't need trained psychologists to administer it and get test groups of kids all at once. I do think they believe it to be far more accurate for those on the right tail of the curve than it seems to be. Whether that is actual marketing or clueless administrators it is hard to say.
