Reference the point about about the Check and Training.
The best way to get a handle on the 'subjective' use of evaluating a persons true rating is to collate the checkies score.
To do this all you have to do is to keep a record of what each checkie is giving. If checkie A,B, and C are giving score X to an individual/s, and checkie D is giving Y, it may be that checkie D has an agenda that is not in keeping with how the company wants it's evaluations done in an 'objective' sense. The problem may be with the checkie not the individual.
I have been told by a long time Qantas C&T that this is what they do.
If one believes the whole C&T training area is 'compromised' maybe it's time to run.
