A 'medium' rating appears in a transit agency register with no narrative explaining how it maps to the scale. What documentation is required?

Ratings need a supportable explanation tying them to defined scale criteria. A "medium" on a transit agency register with no narrative mapping is not defensible for governance or audit. Confidentiality stamps that hide medium ratings from executives block oversight. Claiming medium always means prior-year budget underspend invents an unrelated rule. Replacing every medium with high to force funding inflates the register. Exam caveat: document why the chosen level matches the legend. Operational check: require a short criteria citation on each new or changed rating, sample medium items for missing narratives, and remediate before the next board packet. Train raters to write one evidence sentence linking facts to the official civic scale band. In municipal practice, record the rationale in the risk procedure or committee minutes so future staff apply the same rule under budget pressure. Re-validate after the next seasonal peak or org-chart change to confirm the civic control still holds as designed for residents and staff.
