There are five Grade A events outside of the Grand Slams that carry the greatest ranking points on the Junior Circuit. To be eligible for a year-end ranking a player must, amongst other stipulations, have participated in a minimum of three Grade A tournaments.

As these tournaments are held in higher esteem they are also held to higher organisational requirements. The tournaments have a wide geographical range, with Mexico, Japan, Italy, USA and Brazil acting as hosts, allowing players from all over the world to have the opportunity to attend.
