Slate...every MOC has 10 candidates that they can nom on one slate. This is true for Cong or Sen. MOCs can have 5 charges at one time, this means sometimes they have 2 slates to fill. Each slate is 10. It is not a list of 20 and they pick the highest 2, it is 2 separate slates of 10. The MOCs determine how the slat eis presented to the AFA. Alphabetically, rack and stack, or principal
WCS Whole Candidate Score. This is the score that board assigns to you after rating your packet. This score is then places against the slate. YOUR WCS includes PAR (prior academic rec..i.e. gpa, SAT/ACT), ECs (leadership, sports and CFA), and recs/essays (teacher and ALO). Points are given and assigned to you, now known as your WCS.
The candidate with the highest WCS on the slate wins the appointment. Thus, going back to how competitive you are against your slate.
Remember MOCS have candidates across districts throughout the state. For our DS, he was the only one from our cong to get a senator nom, let alone both. He was the only one in his school district to get a cong., we had 2 congs for the school district.
