I look at the description of the Instruction skill, and I see it mentions a dice test to learn a skill. I can find no other reference to that process however. Teacher seem to come into play only for magicians to learn spells. So far as I can determine, skills are just learned via Karma. Or have I overlooked something?

Any thoughts?

I'm reasonably sure, that it is meant to do more, but that this information has somehow failed to be printed in the book... maybe that will be covered in the FAQ eventually.

In previous editions, Instructors were used to reduce training time. You can reference the Shadowrun Companion for SR3 for comparable materials if you want to include training times in your game.
