Canada, US, Australia may all be different. I have no idea.
Canada - 15 hours ground school, 60% on TC glider exam, 6 hours glider training under supervision of a Glider Instructor, including a minimum of 1 hour dual and 2 hours solo (including 20 take-offs and landings) and pass a skills test.
No requirement for cross-country or off-field landings.
Of course, all ab-initios take much longer than the minimum hours.
