What Illinois publishes

The agencies behind our Illinois listings publish pass or fail results. None of them publish a score out of 100, so every Illinois score on GradeLocal is a GradeLocal score, worked out from the official result.

How GradeLocal grades Illinois restaurants

For pass or fail results, a pass is an A, a pass with conditions or a required reinspection is a C, and a fail or a closure is 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.
