With the amount of money resorts charge for a private ski lesson these days, you would think your teacher would come back with you and renovate your basement.
Charging upwards of $700/day, there's no guarantee that you'll get what you pay for. You could get a fantastic person with 20 years experience and a PSIA level 3 certification, or a young lady from Switzerland who speaks broken English and it's her first year in the states.
Unless you ask for something specific, your resort of choice will merely go down their list and book the next available instructor whether they've taught for 16 years of two.
So how do you know who to ask for? Check out Ski Pro Connect, a Web site that links instructors with potential clients. The idea sprang from a Canadian and Austrian business alliance to enhance the level of customer service and the ski experience of students by allowing instructors from all over the world to place an e-business card online, share their credentials and communicate with clients before they hit the snow.
It's the world's first ski and snowboard instructor directory. All of the listed instructors are affiliated with a particular resort (‘freelance' instructors are outlawed in the U.S., but you may find some listed for European countries).
You can search by country or resort, or by doing an advanced search based on nationality, qualifications, languages spoken, and more. You can then e-mail your instructor of choice directly through the site with questions on personality, availability, teaching techniques, and even current snow conditions.
The site is still building so there may not be that many instructors listed for your particular resort. Make sure you let your fellow teachers know that they can sign up and market themselves.
Another great place to check out is Facebook. PSIA maintains a presence and you can search, for example, "PSIA Utah" to find a variety of instructors to interview.
