The FY17 Staff Corps O6 promotion board basic statistics are here. I don’t have the specialty specific ones yet, but I’m sure they’ll be coming soon.
Let’s go over the basic stats for Medical Corps so that everyone understands them as they can be very confusing.
According to page 2 of the convening order, the promotion opportunity was 70%. The number of people in zone was 91. In order to find the total number of officers they could select for promotion, you take the promotion opportunity x the size of the zone:
(70% promotion opportunity) x (91 officer zone size) = 64 officers could be selected for promotion
As you see in the stats, they selected exactly 64:
- Above Zone – selected 32 of 183 or 17.5%
- In Zone – selected 31 of 91 or 34.1%
- Below Zone – selected 1 of 150 or 0.7%
As you can see, even though the promotion opportunity was 70%, the chance you got selected in zone was only 34.1% because selects came from above and below zone.
