Skaters who reached the age of 13 by July 1, 2018 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. Competitors were chosen by their countries according to their federations' selection procedures. The number of entries allotted to each ISU member federation was determined by their skaters' placements at the 2018 World Junior Championships in each discipline.
At each event, skaters earned points toward qualification for the Junior Grand Prix Final. Following the seventh event, the top six highest-scoring skaters/teams advanced to the Final. The points earned per placement were as follows.

There were originally seven tie-breakers in cases of a tie in overall points:
Highest placement at an event. If a skater placed 1st and 3rd, the tiebreaker is the 1st place, and that beats a skater who placed 2nd in both events.
Highest combined total scores in both events. If a skater earned 200 points at one event and 250 at a second, that skater would win in the second tie-break over a skater who earned 200 points at one event and 150 at another.
Participated in two events.
Highest combined scores in the free skating/free dance portion of both events.
Highest individual score in the free skating/free dance portion from one event.
Highest combined scores in the short program/short dance of both events.
Highest number of total participants at the events.
If a tie remained, it was considered unbreakable and the tied skaters all advanced to the Junior Grand Prix Final.
