Document attached shows gradings to be used to assess whether a player is eligible to play up for a higher ranked team in the same division (League Regulation 6.8)
Reg 6.8.Where a club has more than one team in any division a player may only play for a team higher than the one for which he/she is registered in that division provided that that player's grading at the commencement of the season is lower than the gradings of the top two players already registered for the higher team concerned.
Note the Team Checker only checks eligibility in terms of team rankings. It is not able to check for eligibility under Reg 6.8. The Team Checker and these gradings should be used together if you are dealing with a player potentially playing up to a team in the same division as that for which he/she is registered.
