2021–22 ISU Challenger Series
It was the eighth season that the ISU Challenger Series, a group of senior-level international figure skating competitions, was held.[1] The 2021 Asian Open Trophy, which was held on October 13–17 in Beijing, China, was intended to be a Challenger Series event.However, as only the men's and women's singles events featured international participants and the total number of ISU member nations represented at the event totaled nine, it did not meet the necessary criteria to qualify for Challenger Series status.Skaters were eligible to compete on the Challenger Series if they had reached the age of 15 before July 1, 2021.The ISU Challenger Series rankings were formed by combining the two highest final scores of each skater or team.
