Club Marks do not form part of the promotion criteria. Assuming that you have completed the required number of games :
Level 7-6 Three assessments. If you achieve the minimum average mark or higher, you get promoted
Level 6-5 Three assessments. If you achieve the minimum average mark or higher, you get promoted.
Level 5-4 Five assessments. If you achieve an average of 73 or higher, you fulfil that part of the criteria. If you cant get the 5 assessments in, there must be a minimum of 3 assessments which must average at least 73. You then must be in the top 50% of referees on your league (Club marks).
So basically, club marks only count if you are a 5-4 candidate and you don't get all your assessments in (which shouldn't happen).
CLUB MARKS DO NOT MATTER!
