How do I advance as a grand master?

A grand master judge is a master judge who has 100 experience points (including 50 or more judging points) and service to the BJCP. The service includes grading at least 50 exams plus additional work. A total of 240 grand master service requirement (GMSR) credits must be earned. See Grand Master Service Requirements for the full details. For each additional Grand Master rank, the same requirements must be met again (experience points, judging points, exams graded, GMSR credits).
