It cannot be over emphasised that kiting, predictably enough, is about being able to control a powerful kite. Surfing, wakeboarding etc etc mean nothing at the learning stage.
That means launch, land, manoeuvre and troubleshoot unpredictable weather and crowd conditions.
IMHO, the best thing a student kiter can do is buy a decent quality twin string stunt kite for around $60 from a hobby or toy shop (not necessarily a brand name 'trainer' kite that cost upwards of $300) and fly the thing for at least 25 hours before even turning up for a lesson.
Put it up at 12, run it through the window as low to the ground as possible, flip it over and run it back the other way, close to the ground as possible. (This is impossible on land with a traction kite.)
Loop it, loop it 10 times one way, back the other until it's untangled. Put it at the edge of the window and hold it there till it almost stalls, then recover it.
Big kites, little kites, bars or reels, they all conform to the same laws of physics.
All learning is self learning, no one teaches us anything. An instructor presents the information, the student chooses to learn it or not.
Now, with some kite skills, turn up for a lesson to learn how the big kites are rigged, how to control the power (sheeting, trim) and what drills to practice so as to become instinctive in an emergency.
Take that away, put 10 hours on the big kite, translate the kite skills from the stunt kite to the big boy.Rig it a few different ways, pull the safey in an appropriate area and become familiar with it.
Maybe time to hit the water for a body drag, maybe time to get some advice off an experieced kiter, maybe time for another lesson.
Ask questions, read, watch and observe.
Small steps till that first day you come to shore and realise with joy in your heart.
"Wow, I just stayed upwind."
