Katie Nutt, from Standlake, struck gold in all three disciplines at the National Championships in Hazelwood Ski World, Lincoln over the weekend.
Competing in the Under 14 category, the 13-year-old posted a personal best in the slalom final with five buoys at 14m and also leapt a best of 13.2m in the jump final.
The Bartholomew School pupil, who trains at Oxford Wake and Ski Club, with coach Steve Glanfield, completed her hat-trick with gold in the overall category.
She qualified for the ladies open trick final where she finished fifth.
Nutt is next in action this Friday at Thorpe Park, before she represents Great Britain at the European and African Junior Championships in Sesena, Spain, which take place later next month.
