Level 5 tower in a very high cost of living area. It took about 3-4 months from when I walked in the door to get D3 (GC). I've been here about 8 months and am close to certifying on LC. I'm not at your typical level 5, as we are class B and have a multitude of other things going on that won't/don't happen on a daily basis at most other airports. The training here has been great, but a very slow going process. I got GC just above minimums and just hit minimums on LC last week, so you can do the math on how long it can potentially take. Every place will be different depending on the operation, the person training and even who your trainers are. A friend of mine started the same day at a different low level tower and was fully certified within a couple months and is already transferring out to a new place. Every situation, facility, person, etc is unique so definitely plan your life around what you can actively afford, instead of what you will potentially be able to down the road.
