How is my ITF junior ranking worked out?

The Combined Junior Ranking counts results from the last 52 weeks:

• your six best singles results, plus
• one quarter of your six best doubles results,

from Junior Grand Slams, J500, the ITF Junior Finals, international team competitions and J300, J200, J100, J60 and J30 tournaments.

Other rules:

• You only earn points once you win a round in the main draw (or a round robin match). A first-round bye doesn't count, but a walkover or a retirement after the match has started does.
• If you play two editions of the same J100 or higher event within 52 weeks, only your better result counts. Results from the same J60 or J30 can count more than once.
• Ties are broken by points from Grand Slams, then by points at each grade going down (J500, then J300, then J200 and so on), then the same for doubles.
• You must register for an ITF junior IPIN membership to enter and be ranked.
