The island currently boasts five athletes competing in ski or snowboard cross at International level.
“Despite its size, the Isle of Man has a unique ability to produce hugely talented athletes across a range of sports,” the four-time Olympian said.
The first intake will begin on 1 October in Austria.
Gillings-Brier said the initiative will allow young Manx people the opportunity to travel off island by themselves in a safe snowboarding environment with access to Olympic coaches.
She said: “I travelled to Canada when I was 16 to train and compete and I know first hand how daunting leaving home can be, not just for me but also my parents.”
“This is a great opportunity to spend six months abroad in a supervised environment with a group of other snowboarders and gain some excellent experience.
“I’ll be heading out to Austria with everyone else on the 1 October as I’m targeting my fifth Winter Olympics at Beijing 2022.”
The 33-year-old became the first British snowboarder to compete at four Winter Olympics in Pyeongchang in February, reaching the quarter-finals.
She previously finished 15th at her first Games in 2006, aged 20, eighth in 2010 and ninth in Sochi four years ago.
