Differences in Italian vs US soaring instruction?

Can anyone who is familiar with soaring instruction in the US and
Italy comment on the differences? I ask because I have started
training a 'student' - actually an Italian licensed glider pilot - who
wants to add US glider ratings to his US commercial and CFI
certificates. His flying is generally very good, but I have already
noticed that there are things he is not familiar with that any US
glider pilot with a hundred flights would certainly know.

So far, I've noticed that there are certain wing runner signals he is
not familiar with - I assume this is because Italian procedures differ
from those in the US. He also has obviously had no instruction in
formal glider XC planning (as opposed to actually flying XC - this he
has done) and has never heard of the PTS accuracy landing as we do it
in the US.

I would appreciate as much information on the differences between the
US and Italian systems of instruction as possible, mainly so that I
can identify the likely problem areas and make sure we cover them in
depth. I've tried to find the Italian equivalent of a glider PTS, and
have had no luck at all.
