What exactly is a murder board? Murder Board is a term that was originally coined by the U.S. military and referred to the practice of preparing people for oral exams – particularly for oral exams related to becoming an instructor. A panel of several people would be convened to hear the presentation of the candidate, and to become the worst set of students that this instructor would ever face – and to see how they would handle the frustration. humiliation, and the general situation.
