Jackson twice skipped Team Scotland at the World Junior Curling Championships. Her first was in 2016, when she led her team of Naomi Brown, Rachael Halliday and Rachel Hannen to a 2-7 record. This relegated Scotland to the World Junior-B Curling Championships for the following season. In 2017, she once again skipped the Scottish junior team. She and teammates of Brown, Mili Smith and Sophie Sinclair won the Junior B championships, earning the right to represent Scotland at the 2017 World Junior Curling Championships. At the World Juniors, her team continued her winning ways, finishing the round robin tied with Sweden's Isabella Wranå rink for first with a 7-2 record. In the playoffs, she lost to Sweden in the 1 vs. 2 game, beat Canada in the semifinal, but lost again to Sweden in the final to claim the silver medal. Jackson was invited to be Scotland's alternate at the 2018 World Junior Curling Championships on a team skipped by Rebecca Morrison. The team finished with a 3-6 record, and Jackson played in two games.
