What Washington publishes
The agencies behind our Washington listings publish rating words or placards and violation counts. None of them publish a score out of 100, so every Washington score on GradeLocal is a GradeLocal score, worked out from the official result.
How GradeLocal grades Washington restaurants
Rating words and placards are translated into a GradeLocal letter. The table below shows how the most common results were translated.
For violation counts, we count every violation in the latest inspection. None is an A, 1 or 2 is a B, 3 to 5 is a C, and 6 or more is a D. An emergency closure order is also a D.
Results with no score of their own get a set score for each letter: A is 95, B is 85, C is 72 and D is 50.
There are four letters, A to D, with no F. The same rule applies in every state, and the cutoffs are never adjusted for a state, county or city. We always use the latest inspection.
