By competing in a Grade 5 or higher tournament, Ranking Points are awarded, based on what stage is made and the grade of the tournament.
These ranking points are tallied up over the year, using a maximum of six events except for veterans which are three events. And this goes on a leader board for County, Regional, and National Rankings. To improve your ranking, you have to play in Grade 5 or above (Fast4's are the common regularly staged one-day tournaments). If you win a match in the competition you gain ranking points, depending on what grade and matches you win, points are allocated accordingly (see LTA Website for details).
