Nicole Ritchie, 18, who trains at Glasgow Ski and Snowboard Centre in Bellahouston Park, is now Britain's highest-ranked seed after she achieved the best score possible for the season.
The former Craigholme School pupil is also the first Scot to achieve such a score since records began in 2005.
Nicole, who left school this summer, will spend the winter racing on snow across the world in a bid to take the snow slopes title as well.
She is also aiming to qualify for the Winter Olympics in 2018.
All skiers enter the rankings with 999.9 points, and throughout their career the challenge is to reduce the number to zero with good results.
Nicole, from Newton Mearns, who has been the top Scottish athlete for four years, has devoted hours to training and competing while also doing her school studies.
She said: "I have been there or thereabouts in the past few years, but I have never actually reached zero points, so it was good when the list came out and I was told.
"It doesn't just happen - it takes a lot of hard work and training in the gym."
Later this month, Nicole will head to Austria to join the Scottish Alpine Team with whom she will compete outdoors throughout the winter against the best skiiers in the world on the international circuit.
Nicole, who also currently holds the British Schools title, took up skiing aged just three on a family holiday in Colorado. Her dad, Gordon, 53, was a keen amateur skier.
She now trains in the gym or on the bike every day in the summer as well as training at XScape and Bellahouston.
She will be based in Austria from next month, before heading to America for the ski season from November to April.
Nicole said: "There are a couple of younger girls coming through, so I have a lot of competition on the [artificial slopes] just now.
"I don't know how I keep on doing it - but somehow I keep on coming out on top. I don't know what it is!"
Now she has left school, Nicole can focus solely on skiing and her goal of trying to break in to the World Cup circuit and qualify for the Winter Olympics in 2018.
She said: "Hopefully, with getting the snow time - because that is the problem in Scotland - over the next year in America I'll improve my points and try to take another step towards my goal of the 2018 or 2022 Games."
