From everything I’m gathering, they are scoring this like an Enlisted Force Distribution Panel (EFPD) - refer DAFI36-2406. Board members will have wiggle room to place value on the different grading criteria(leadership/adaptability&potential/aptitude). For example, board member 1 could place more value on WG/CC ranking, while board member 2 could place more value on awards/decs/OPRs. So the same package these two board members grade could be a few points different. Needless to say, each applicant will get an overall score (combined from each board member’s score), important piece here are ties that are right on the cut off line. Those packages will be discussed to split the tie, meaning the board will come together and review and determine who makes it. Board members will explain why they scored the package the way did, and eventually come to the conclusion on which applicant should make the cutoff.
just my experience sitting in a few boards. Take it with a grain of salt.
