Waze uses a point system to track use of the the Waze client application, and the Waze Map Editor. Different actions give you different numbers of points. Your point total is compared to the point totals of other Waze users to determine your Waze rank. Wazers who edit the map also have an edit count and an editor rank.
Your total points collected from all types of activities are compared to others in your Country or State depending upon what server you are located. You are also compared to everyone on both servers around the world. This rank is displayed in various locations on the app and in the My Dashboard through the web interface. The highest rank is 1.
