How to read a nursing home's 5-star rating (and where it lies)

The government’s 5-star rating is the most-cited number in senior care, and the most misunderstood. It is not one measurement — it is three, blended together, and one of them is far more trustworthy than the others.

The three parts

The overall star combines: (1) the health-inspection rating, based on unannounced visits by trained state surveyors; (2) the staffing rating; and (3) the quality-measures rating. The inspection rating is the one outsiders verify on the ground. Staffing is now drawn from payroll data (a real improvement), while quality measures still lean heavily on data the facility reports about its own residents.

Why the overall star can mislead

Because self-reported components feed the overall score, a facility with a mediocre inspection record can lift its overall rating with strong self-reported numbers. Investigative reporting — most prominently a 2021 New York Times analysis — found the gap can be substantial. A five-star overall built on a two-star inspection history is telling you something very different from a five-star built on inspections.

How to read it the honest way

Look at the health-inspection star first and separately. That is why every facility page here shows the three components un-blended and flags any home whose self-reported ratings run two or more stars above its inspection score — a “rating divergence.” Then read the actual deficiencies: their severity on the A–L scale, whether any reached immediate jeopardy, and how recent they are. A single old, low-level citation is noise; a pattern of harm-level findings is a signal. Star ratings are a starting point, never the whole story.
