How the grade is worked out
What counts: Applications of California restricted materials, and aerial applications.
What counts as inspected: A priority application counts as inspected when the county recorded a use-monitoring inspection at the same site ID within a day of its dates.
Thresholds: A at 50% or more, B at 30% or more, C at 15% or more, D for anything above zero, F for none.
The grade is this publisher's editorial rating, not a regulatory finding. A county whose inspection records have not been obtained is not graded, because an absence of records is not evidence of an absence of inspections. Every figure comes from the county’s own reports; if the county disputes one, it can say so.
