This September, Prep 3 Georgie had almost 7 inches of her hair cut to donate to The Little Princess Trust.
The charity provides real hair wigs to boys and girls across the country who have lost their own hair through cancer treatment.
The challenge is the first of many which will mark 140 years since Bishop Benson founded the High School in 1880.
From climbing mountains and charitable acts to setting themselves an ambitious personal goal, the school is hoping that all its students can take part in completing a challenge to commemorate this milestone, whether that be solo or with friends. No challenge is too big or too small.
