The first part of the training in France is the “pré-formation”. To get onto the course you need to have passed your “test technique” which involves doing a slalom spécial (the tight one) within 20% of a time set by a top skier. The time junior was up against was set by the French champion and 3/85 candidates got through. After the “pré-formation” it’s the “Euro test” and so it goes on, plus you have to be handy on a snow board. It takes years and every step is highly competitive/selective.
Other national qualifications are accepted in France, but not the ones that fall far short. It’s the same in swimming, my nephew was a lifeguard at a pool in the UK at 15 IIRC with very basic training. In France you have to be over 18 and complete a course that is much more demanding in both swimming and medical terms – you have to pass the same first aid course as firemen.
Cycling too, it took a very competent mountain biker from our club a year to complete the training for his cycle guide qualification – first aid, how to run a business, how to teach, skills test on a BMX, MTB, trials bike and roadie, orienteering/map reading, multiple field/practical courses, a log of rides and teaching practice.
