If your rating has not changed for a long period of time, it may be because you have not accrued enough Activity Points to move to the next rating tier. Each rating tier has a minimum amount of Activity Points you must accrue within a recent amount of time to qualify. It is very common for a tester to have the Quality Scores associated with higher tiers but not have reached the minimum amount of Activity Points. If your rating ends in a .2643% (49.2643%, 74.2643%, 84.2643%, 92.2643%), it is an indication that you have a Quality Score that would qualify you for a higher tier but have not collected the minimum amount of Activity Points. You can collect Activity Points by participating in Test Cycles. Each action you complete within a cycle will gain you Activity Points.
