Skaters who reached the age of 13 by July 1, 2007 but had not turned 19 (singles and females of the other two disciplines) or 21 (male pair skaters and ice dancers) were eligible to compete on the junior circuit. Unlike the senior ISU Grand Prix of Figure Skating, skaters for the Junior Grand Prix are entered by their national federations rather than seeded by the ISU. The number of entries allotted to each ISU member federation is determined by their skaters' placements at the previous season's World Junior Figure Skating Championships in each respective discipline.
