I’m sure each trainer/hub is different, but here your training experience is going to vary significantly based on your skill level.
I had my CDL before I left package and went to feeder too. I spent like 1 morning practicing in the yard before my trainer was confident that I could actually drive and then we spent the rest of the “non-production” week doing the training videos and paperwork in the morning and then doing mostly CPU jobs after lunch. I wound up getting paid for both weeks because I was moving actual loads with my trainer, and the bonus was that I got to see a ton of CPU locations ahead of time and was familiar with them before I was out on my own.
Same for the second “productive” week, after the first night the second trainer would fall asleep for most of the drive and wake up when we got there. He said he wouldn’t have been sleeping if he was worried about my driving.
On the flip side, I’ve since seen new people spend all week in the yard because they just suck at backing up. I’ve seen people rotate through several on-road sups hoping that one of them could break through to the trainee. Hell, one guy even had two on roads out there trying to help him. Some of them didn’t even make it to the production week.
Once you’re through training just don’t do anything stupid, don’t hit anything, do your pre and post trips, and get your loads there on time and you won’t have any issues qualifying.
