The event was held on 2–8 March 2015 at the newly constructed Tondiraba Ice Hall in Tallinn, Estonia.

National associations selected their entries according to their own criteria but the ISU mandated that their selections achieve a minimum technical elements score (TES) at an international event prior to the Junior Worlds.

The term "Junior" in ISU competition refers to age, not skill level.

Skaters may remain age-eligible for Junior Worlds even after competing nationally and internationally at the senior level.

Based on the results of the 2014 World Junior Championships, the ISU allowed each country one to three entries per discipline.
