It depends which boards you're talking about. BUPERS has the schedule up for the boards that are for current military. The boards that decide on civilians and BDCP aren't really posted or shared. You usually don't find out until after the fact, unless someone's recruiter happened to get the info and then pass it on. Plus, certain selection boards meet more frequently than others. My recruiter told me that in the fall the Aviation board was meeting almost weekly where as others will go months in between meetings.
Question: Is it frowned upon to share that information? Meaning if you know when a board met are you allowed to share that info?
