ISU Challenger Series

The ISU Council decided to create the series at its February 2014 meeting.[1] Eleven competitions were selected in June 2014.[2] The Triglav Trophy dropped out by October 10, 2014, resulting in a series composed of ten events.[3] The Nebelhorn Trophy, Finlandia Trophy, Ondrej Nepela Memorial, and Golden Spin of Zagreb are the "core group".[4] The event criteria were published in April 2014,[5] and revised in August 2014.[6]

The notice on the ISU Challenger Series Synchronized Skating was announced on May 10, 2019, which is for the discipline of synchronized skating and is held separately from the other ISU Challenger Series.[7]

Asian Open Classic was planned to be included in the 2019–20 season, but ISU transferred the event holding right back to Asian Open Trophy later.[8]

In the 2020–21 season, due to the COVID-19 pandemic, it was decided to hold the Challenger competitions as individual events, rather than as a series.[9] Entry limits per country were also removed.[10]

Each skater or team is permitted to compete in up to three ISU Challenger Series events. Their two highest scores determine the final ranking.[5]
