No--at least, not according to everything I've been receiving (as recently as yesterday) about my 16 Sep class date....

I think what may have happened was a poor choice in wording for the new hires not in the first class. I gather they were told something along the lines of "there will be a delay in the start of [your] training, so [your] class date will be later than Sep 16th." With only 12 per class, it's easy to do the math on how many will need to start at a later date. I have no idea how they determined who would go in which class, but I'm certainly happy to have been selected for the 16th!
