Q graders need to attend and pass a one-day Q calibration once every three years in order to maintain their license. During the calibration we ask Q graders to cup three tables of six coffees each and score them in line with their peers. A passing score on at least two out of three tables will result in the renewal of a Q certificate for three additional years.
