    Develop a function that determines how many assessment criteria received identical scores from two human graders and an automated grading system when evaluating a student's essay. The function should compare the scores assigned by both graders and the automated system for each evaluation criterion (such as grammar, structure, and vocabulary) and count only the instances where all three assessments gave the exact same score for the same criterion.
