A MOC can have 5 appointees charged to the district at any point in time. Since there are four class years, each MOC will have two slates every few years if nominations are managed properly.
You won the MOC lottery. Your district did not have enough candidates to fill two slates and you received nominations for both slates - you doubled your chances of winning the district.
I thought they had 5 ... the four class years and the incoming class.
I thought two states would be caused by one of the previous appointments charged to the MOC left the SA.
They can have 5 attending
and charged to them at the same time - there is no law regarding how they are distributed. SA's educate MOC's very well on the process so normally MOC's have one slate per year and two slates every fourth year.
Not all of those appointed from a MOC's slate are charged to them - a candidate may be nominated by a MOC, but then appointed as a Qualified Alternate (QA) or Additional Appointee (AA). QA's are the top 150 from the National Waiting List in order of merit. AA's are the remaining 200-400, not necessarily in order of merit. QA's and AA's use the MOC's nomination, but do not count against the five slots.
