The three levels of instructor is interesting and makes sense.
Another difference seems to be orientation in that there is some
expectation that the student may fly cross country some day. I don't
think this is part of USA instruction. I would also guess 80% of the
US instructors have no official cross counry credentials like the
Silver C. But again, this is probably not a problem as you can gain
the knowledge to teach cross country skills by reading the texts on
the topic.

thanks,
