Converting non-skier adults of child-bearing age into committed skiers is the most important thing a ski school can do for the long term benefit of the industry. Most young adults who become enthusiastic skiers will very likely see to it that their spouse and all their progeny are skiers as well. Win over one 20-something adult, and you have a good chance of getting a whole family you'd never have gotten otherwise.
Sometimes ski schools seem to think teaching young kids to ski is their most important task. That's an important maintenance task, but not a growth plan. The parents of those kids are already committed to skiing, and the kids are already on the mountain. The deal is already done. You don't want to lose them, but simply keeping them on the mountain is not going to make the numbers increase.
Converting the non-skiing young people who will one day soon have kids is the fastest way to build a growing clientele.
If PSIA could market a reliable branded product of this sort to ski area management and prove it works, then PSIA would become essential to ski area management.
Can that happen?
