To maintain their standing as active and licensed Q Arabica Graders, individuals are required to engage in a calibration process every three years. This ensures a thorough assessment of their ability to accurately assess coffee quality based on acquired expertise, knowledge, and the standards/protocols acquired during Q training. Participation in calibration is obligatory for Q Graders seeking to uphold their active status.

​

The calibration procedure involves the evaluation of three cupping tables, each comprising six samples of coffee with distinctive attributes. Successful completion requires Q Graders to be in calibration and pass at least two out of the three tables, allowing them to renew their licenses and continue their designation as Licensed Q Graders. Following a successful calibration, the Q Grader license is valid for an additional 36 months, commencing from the day of the calibration course.
