not sure about that pal. BASU means absolutely fuck all in france or italy where you've gotta pass a eurotest to qualify. furthermore, in austria and switzerland if you are a good skier and/or know the right people you can instruct at ski schools with no qualification whatsoever. so in that respect, a BASI qualification is pretty fucking worthless in europe. i believe it is sufficient in north america, NZ etc.
i think instructor courses are worthwhile only if you:
A) wanna do a ski season but haven't skied much/at all
B) actually want to pursue it as a profession.
all the guys, particularly in places like val d'isere, verbier, wherever else, that do courses paid for by daddy, at obscene cost, because little johnny either can't or won't get a proper ski job, so they can strut about pretending to be instructors, while learning to teach the textbook snowplow on powder days are, in my view total morons. the number of fucking bellends, particularly from basecampgroup in val d'isere who would challenge people to races and other mindless shit because they grossly overestimated their own skiing ability defied belief when i did seasons in val
if you want to become an instructor, fine do a course, but why commit to a proper course rather than some half-assed BASI bullshit that is fucking pointless? if you don't have any intention to become a professional, why the fuck pay something in the region of £10 000 (living costs included) when you can get a job, ski when you want, and not look like a bellend?
