That's what i figured it would be like. What i still don't get though is what about these news reports that come out saying that an air traffic controller "trainee" had a deal or a close call? Does the FAA specifically mandate that a controller doing on the job training can't go live before they're fully certified?
You are a trainee (or developmental) until you are fully certified.
"Going live" is a part of the process of getting fully certified. When you arrive at your new facility, you will spend some time in the classroom. There you will be drawing maps, learning the procedures, letters of agreement and SOPs specific to your area. Many, but not all, facilities also include a phase of simulated control practice.
Then you start on-the-job training or OJT. This is when you plug in to the position and start talking to real pilots. Your OJT instructor will be plugged in directly with you and the instructor remains responsible for the operation of the position. If you, as the trainee, screw up, it would not be uncommon for folks to say that "the trainee had a deal", even though it is the instructor who will ultimately get the blame.
Most places do certifications on each position individually. As a trainee, it is possible to be checked out on one or several positions without being fully certified. You will work those positions without being plugged in with your OJTI. If you, as a trainee, are working a position on which you are checked out and have a deal, it would then be quite accurate for folks to say, "a trainee had a deal."
