Welcome Will. Another BC one here, excavation and dirt work down on Vancouver Island. "They can wire anything, they freeze on paper" is the same thing I see on the business side. Guys who can run a machine all day and read ground better than anyone, then the quote sits in the truck for a week because writing it down is somebody else's job in their head. Same person, same competence, different medium. The ones I've watched get through it didn't get better at writing, they stopped starting from a blank page. Same structure every time, so the task became filling gaps rather than producing something. Curious whether that's what you see on the exam side too, or whether the paper problem there is more about how the questions are worded than the writing itself.
