Nursing Home Star Ratings Explained
Every Medicare-certified nursing home carries a federal star rating, and almost everyone reads it wrong. The overall star is not an average of the three underlying ratings — it is calculated by a specific rule, and once you know that rule you can see exactly why a facility scored what it did. We tested the rule against all fifteen facilities we profile in Fort Myers, and it reproduced every single overall rating correctly.
Verified · CMS data as of 26 Aug 2026What the three ratings actually measure
They are not equally reliable, and knowing which is which changes how you read a facility.
| Rating | What it is based on | How much to trust it |
|---|---|---|
| Health inspections | Unannounced state surveys over roughly three years, plus complaint investigations. The most recent survey carries the most weight. | Most reliable. Independent inspectors, and the facility cannot prepare for it. |
| Staffing | Payroll-based journal data: registered nurse hours, total nurse hours, weekend staffing, and annual turnover of nurses and administrators. | Very reliable. Verified against actual payroll records, so it is difficult to inflate. |
| Quality measures | Clinical outcomes such as falls, pressure ulcers, infections and hospital readmissions, drawn partly from assessments the facility completes itself. | Softest of the three. Partly self-reported, so treat a high score here as encouraging rather than conclusive. |
Health inspections are graded on a curve
Inspection ratings are relative, not absolute. Within each state, roughly the top 10% of facilities get five stars and the bottom 20% get one, with the rest distributed between. That means a one-star inspection rating in Florida means “worse than most Florida facilities” rather than “fails a fixed standard.”
How the overall star is calculated
This is the part almost no guide explains, and it takes about thirty seconds to learn.
- 1Start with the health inspection rating. That is your baseline. Nothing else matters as much.
- 2Add one star if staffing is five stars. Subtract one star if staffing is one star. Anything in between changes nothing.
- 3Add one star if quality measures are five stars. Subtract one if they are one star. Again, the middle does nothing.
- 4Cap the result between one and five. CMS also applies additional limits, so a facility with the weakest inspection record will not reach the top rating on strong staffing alone.
Why this matters more than it sounds
It means a four-star staffing rating is worth exactly nothing to the overall score. Only a five changes it. So two facilities with visibly different staffing can show the same overall star, and a facility can be genuinely well staffed while still displaying two stars because its inspection record is poor. The overall star hides that completely.
The formula tested on fifteen Fort Myers facilities
We applied the rule to every facility we profile. In all fifteen cases the calculated result matched the overall rating CMS publishes. Work down any row yourself and you will get the same answer.

| Lee Memorial Hospital SNU | 5 | 5 | 4 | 5 | 5 |
| The Preserve | 5 | 4 | 4 | 5 | 5 |
| Larsen Health Center | 3 | 5 | 2 | 3 + 1 = 4 | 4 |
| Cedarbrook | 2 | 3 | 5 | 2 + 1 = 3 | 3 |

Read the middle rows carefully
Cedarbrook, Eagleridge and Aviata all show three stars. All three got there the same way: a two-star inspection record lifted by top quality measures. Meanwhile Fort Myers Rehabilitation shows two stars with a better staffing rating than Cedarbrook. The overall star ranks them in the wrong order for anyone who cares about staffing.
How to actually use the ratings
- Open the three sub-ratings before anything else. The overall star is a summary of a summary.
- Read the inspection detail, not just its star. Two facilities with the same star can have very different citations. Severity matters more than count.
- Look at turnover, not just hours. Turnover is the most under-used number on the whole federal profile, and it says more about daily life than any star.
- Check registered nurse hours separately from total nursing hours. They are different things and the gap between facilities is large.
- Remember what ratings cannot capture. Whether staff know residents by name, whether call bells are answered, whether the building smells clean. Only a visit tells you that.
- Treat “not rated” as missing data, not bad data. It usually means too little recent inspection history, often after a change of ownership.
The single best question to ask on a visit
Ask a member of care staff how long they have worked there. Then ask two more. If the answers are years rather than months, the turnover figure is telling the truth and the building is stable. It is the fastest reality check there is.
Frequently asked questions
How is the overall nursing home star rating calculated?
It starts with the health inspection rating. One star is added if staffing is five stars and subtracted if staffing is one star. The same adjustment applies for quality measures. The result is capped between one and five, with additional CMS limits. It is not an average of the three.
Which of the three ratings matters most?
Health inspections, because they set the baseline and come from unannounced independent surveys. Staffing is the next most reliable because CMS verifies it against payroll data. Quality measures are the softest because they are partly self-reported.
Is a four-star staffing rating better than a three-star one?
In reality yes, but not for the overall score. Only a five-star or one-star staffing rating changes the overall star at all. That is why the overall rating can rank facilities in an order that does not match their actual staffing.
Are star ratings compared nationally or by state?
Health inspection ratings are set relative to other facilities in the same state, roughly the top 10% earning five stars and the bottom 20% one star. Staffing and quality measures use national thresholds.
How often are the ratings updated?
CMS refreshes the data quarterly. Always check the “data last updated” date on the federal profile before relying on a rating you read anywhere, including here.
Why does a facility show no rating at all?
Usually because there is not enough recent inspection data to calculate one, often following a change of ownership or new certification. It is not the same as a low score, but it does mean you have less to go on.
Can I trust a five-star facility completely?
No rating replaces a visit. A five-star rating means the measurable indicators are strong, which is meaningful. It says nothing about whether the staff are kind, whether meals are decent, or whether your relative will be happy there.
