There's only 3 possible ways the MOC presented the slate. And only they can tell you which way that was. The 3 ways are:
1. Competitive: this is the most common. The MOC presnts their slate to the academy, in no particular order (that matters) and tells the academy.... Pick one.
2. Ranked: the MOC presents a slate and the list is ranked #1-#10. The academy must start at #1 and offer that person the appointment, unless their application isn't complete or if they aren't 100% qualified. In which case they must go to #2 and so on. Words like primary don't mean a thing. The academy must start at the top and work down until they find a completed 100% qualified applicant.
3. Principal: a pseudo combination of the first 2 methods. The MOC presents a list where their #1 person is identified as their Principal nominee. The academy must offer this individual an appointment if their application is completed and they are 100% qualified. Just like method 2 above. The difference however is that the remaining 9 are not ranked #2-#10. They are competitive. If for some reason the #1 (Principal) can't receive the appointment, the academy is free to choose whomever they want from the remaining 9.
Hope this helps better understand the selection process. As I mentioned above, the ONLY person who can say which method the slate was presented, as for you finding out, is your MOC. Contact them. Or wait and sweat it out. Best of luck. Mike.
