Even among agencies with very high standards, the abilities of instructors to teach can vary. I was told, in my Fundies class, that I had to fix my problem with going out of trim when task-loaded, but I wasn't given tools with which to do it. Turned out I needed to move some weight up onto my cambands; once I did that, my tendency to rotate head-up when distracted went away. On the other hand, I have read reports of classes with Beto Nava in Monterey, where quite a bit of time is spent making sure gear is properly balanced.
On the other hand, I would say that gear balancing is something which ought to be within both the mental and physical grasp of most students, without an instructor's help, once the student understands that gear needs to be balanced. I think we have described many times here how it's done -- you need a buddy who can give you feedback on your posture, because bad posture will skew any attempt to balance gear. Once your posture is right, you get horizontal (with confirmation from buddy) and stop moving, and see where you tilt. Then you move things around and try again. It's not rocket science -- again, once you KNOW it can be an issue, and how to check for it.
