The folks who did the CHL training provided all of the forms for us. We arrived early in the morning, had our photos and fingerprints made, filled out the paperwork with their supervision, and then sat in class for the rest of the day.
When we left, all we had to do was wait for the instructor's certification, then mail the whole packet into the state.
We (my wife and I) got our CHL's about 60 days later.
Talk to the people doing the training. If they don't provide the paperwork, ask around for someone who does.
It's worth it to pay a little extra when they provide a package deal.
Never argue with drunks or crazy people.
