the rating system was established before i joined the company.
ussually yes unless auditee is protesting.
I used to having the so-called all-or-nothing rating as well when i started ISO9001:2000 implementation back in year 2001. However, we have revised the rating to "grade 1-5" a couple of years ago in order to properly indicate the performance. Lately, we have revise it again because it was rather ambiguous.
There isn't any requirement for the rating system, so one should establish a rating system that is most effective and would benefits the organization most. If the rating system is not at all relevant, remove it.
