Five-Star Nursing Home Ratings Explained

Five-Star Nursing Home Ratings: What They Actually Measure (And What They Miss)

Key Takeaways

  • A five-star rating measures three specific federal metrics: health inspections, staffing levels, and clinical quality measures—not experience factors like food quality, activity programming, or staff kindness.
  • CMS states that ratings cannot substitute for visiting the nursing home in person and should be used alongside other sources of information.
  • Health inspection ratings are ranked within each state (not nationally), meaning a five-star rating in one state may reflect different absolute performance than the same rating elsewhere.
  • Peer-reviewed research finds limited correlation between five-star ratings and family or resident satisfaction with care.
  • Use the five-star system to narrow your shortlist, then visit facilities in person and evaluate dimensions the data doesn’t capture.

When a family member lands in the hospital and the discharge planner says “you have three days to find a nursing home,” the first thing most people do is look for five-star nursing home ratings. That instinct is reasonable. The federal star system exists for exactly this purpose. But a five-star rating tells you less than most families assume—and understanding what it measures, what it skips, and how it varies by state can save you from a decision you’ll regret.

As of July 2025, there are 14,742 CMS-certified nursing facilities in the United States, housing approximately 1.24 million residents. The five-star system is the most widely used tool for comparing them. Here is what it actually does.

What the Five-Star System Measures

The three domains: inspections, staffing, and quality measures

CMS (the Centers for Medicare & Medicaid Services) launched the Five-Star Quality Rating System in December 2008, adding it to the Nursing Home Compare website so families could compare facilities at a glance. Every certified nursing home receives an overall rating of 1 to 5 stars, with more stars indicating higher quality relative to peers in the same state, according to CMS.

That overall rating is built from three separate domain scores:

  • Health inspections — based on findings from state survey inspections, including the number, scope, and severity of deficiencies cited
  • Staffing — based on registered nurse (RN) hours and total nursing hours per resident day, using staffing data submitted to CMS
  • Quality measures — based on a set of clinical quality measures, including rates of pressure ulcers (bedsores), falls with injury, and residents experiencing worsening pain

For a deeper look at what surveyors actually document, see How to Read a Health Inspection Report Without Getting Lost.

How the overall rating is calculated

The composite score is not a simple average. According to CMS, the calculation starts with the health inspection rating as the base, then adjusts up or down:

  • A staffing rating of 4 or 5 stars adds one star to the overall score, but only if that staffing rating also exceeds the facility’s health inspection rating.
  • A quality measure rating of 5 stars adds one additional star.
  • A quality measure rating of 1 star subtracts one star.

This means health inspection performance anchors the overall rating. A facility with poor inspection results cannot compensate by hiring more nurses. One important safeguard: if a nursing home is an active Special Focus Facility—a CMS designation for homes with a pattern of serious problems—its overall rating is capped at 3 stars, regardless of how it scores on staffing or quality measures.

To earn 5 stars on the staffing domain, a facility must meet or exceed CMS benchmarks for both RN hours and total nursing hours per resident day. The national average sits at roughly 3.85 nursing hours per resident day, but that average masks wide variation between facilities.

Why state-level ranking changes what five stars means

Here is the part most people miss. For the health inspection domain, CMS does not rank facilities nationally. It ranks them within each state. The top 10% of facilities in a state receive 5 stars on health inspections; the bottom 20% receive 1 star; the middle 70% receive 2, 3, or 4 stars. CMS recalibrates these cut points monthly to maintain a consistent distribution within each state over time.

The practical result: a five-star health inspection rating in one state does not mean the same thing as a five-star health inspection rating in another. It means that facility ranks in the top 10% of its own state—not the top 10% of the country.

What Five-Star Ratings Don’t Measure

Experience factors families care about most

A five-star rating tells you a facility passed its inspections well, maintained adequate nurse staffing levels, and performed well on specific clinical outcome measures. It does not tell you:

  • Whether the food is good
  • Whether activities are engaging and varied
  • Whether staff know residents by name and treat them with warmth
  • Whether the facility feels clean and odor-free
  • Whether family members are welcomed and kept informed
  • Whether residents with dementia receive appropriate, patient care

These are not small details. For most families—and most residents—they are the whole point.

Available peer-reviewed research generally finds that the five-star system, which is built on technical quality indicators such as staffing ratios, deficiency citations, and clinical outcome rates, does not fully capture the dimensions families and residents report valuing most—including interpersonal relationships between staff and residents, sense of security, and basic cleanliness. Research published in PubMed Central has examined families’ and residents’ perspectives on nursing home quality in this light, with findings pointing to a gap between what the star system measures and what residents experience day to day.

Studies examining specific regional samples have found limited or no relationship between five-star scores and resident or family satisfaction measures such as privacy, staff relationships, and resident autonomy. Those findings should be treated as directional evidence—not a definitive national conclusion—since the source research draws on specific geographic samples.

Why the gap exists

The gap is structural, not accidental. The five-star system was designed to be auditable and reproducible. Staffing hours can be extracted from payroll records. Deficiency counts can be pulled from inspection databases. Hospitalization rates can be calculated from claims data. Staff kindness cannot be pulled from a federal database.

There is also a concern raised in the research literature: nursing homes can improve their star scores through means other than improving care quality—for example, by changing how they code resident diagnoses or by avoiding admitting higher-need residents who might generate worse clinical outcomes. This concern predates the current rating system revision, but it remains relevant context for interpreting scores.

Separately, as of July 2025, 27% of certified nursing facilities received deficiencies for actual harm or jeopardy to a resident during their most recent survey. That figure sits alongside the reality that five-star facilities exist in every state. The two facts are not contradictory—they reflect that the rating system spans a wide distribution of performance, not a clean binary.

CMS’s own acknowledgment of system limitations

CMS does not oversell its own tool. The agency states that ratings cannot substitute for visiting the nursing home in person and should be used alongside other sources of information when making a nursing home decision.

That is not a disclaimer buried in the fine print. It is a design acknowledgment: the five-star system was built to screen out low performers, not to rank the subtle qualities that make one adequate facility meaningfully better than another for your family member.

When you visit a facility, bring a list of questions the data cannot answer. Questions to Ask on a Nursing Home Tour covers specific topics worth raising. Red Flags to Watch for During a Facility Tour covers what to observe while you’re there.

The Research on Five-Star Ratings vs. Real Experience

What peer-reviewed studies show about satisfaction gaps

The research on this question is consistent across multiple studies, though some of the most-cited work is now more than five years old. A 2021 study published in PubMed Central examined families’ and residents’ perspectives on nursing home quality. That research found that the technical dimensions captured by the five-star system—the ones that can be counted and audited—do not map onto the experiential dimensions that residents and families report mattering most.

Additionally, peer-reviewed research finds that the five-star rating system does not adequately reflect consumer satisfaction, and recommends the system be refined to include a consumer component. That research is now more than five years old and should be treated as directional context.

The picture that emerges from the literature is not that five-star ratings are meaningless. It is that they measure a specific, bounded set of things, and that families should not assume a high rating indicates excellence across all dimensions of care.

Geographic clustering: where high-rated facilities are located

Nursing home quality is not evenly distributed geographically. Research has pointed to a pattern where higher-rated facilities tend to be located closer to relatively affluent areas, meaning lower-income consumers face real supply constraints when trying to access top-rated care. More recently, as of July 2025, 27% of certified nursing facilities are in rural areas, and 20% of residents live in rural nursing homes. Rural facilities often face different staffing markets and economic conditions that can affect their ratings regardless of the quality of care their staff provides.

State-by-State Variation: Why Five Stars Isn’t Always Five Stars

How state-relative ranking works for health inspections

The health inspection domain uses a state-relative scale, not a national one. CMS ranks facilities within their own state and applies cut points that are recalibrated monthly. This design choice was intentional: survey practices vary between states, and a national ranking would reward or punish facilities for differences in how their state surveys are conducted rather than for differences in actual quality.

The tradeoff is that interstate comparisons are inherently limited. A five-star inspection rating means “top 10% in this state,” full stop. Whether that places the facility in the same absolute performance tier as a five-star facility in a different state depends on how stringent that state’s surveying process is and how the rest of its facilities perform.

Staffing variation compounds this. A 2025 study found that in 2023, average reported staffing hours per resident day fell below 3.48 hours in 11 states. That 3.48 HPRD figure was the threshold established in the 2024 CMS minimum staffing rule—a rule that Congress subsequently suspended until September 30, 2034, with CMS restoring pre-2024 regulatory text in December 2025. The staffing benchmarks used in the five-star rating system are separate from those suspended minimums and remain in effect. But the underlying interstate variation in actual staffing levels is real and affects what a given staffing star rating represents in practice.

What this means for comparing facilities across state lines

If you are comparing a facility in one state to a facility in another—for example, because a parent is moving closer to family—a matched star rating is a starting point, not a conclusion. Pull the underlying domain scores. Compare inspection histories directly. Note the states’ surveying contexts if possible.

How to Use Five-Star Ratings Responsibly

Use ratings as a filter, not a verdict

A five-star rating is a floor, not a ceiling. The rating system is most useful as a screening tool: use it to rule out facilities with persistent low ratings or serious inspection findings, then evaluate what remains on factors the data does not capture. A 4-star facility with warm, attentive staff and excellent food may serve your family member better than a 5-star facility where the culture is indifferent.

The inverse also holds. A 1-star or 2-star rating is a meaningful signal worth taking seriously—particularly if the low score is driven by health inspection findings, which according to CMS reflect actual survey deficiencies documented by state inspectors.

Visit in person before deciding

CMS says it plainly: ratings cannot substitute for visiting in person. A facility visit lets you observe staff interactions, smell whether the environment is clean, speak with residents if possible, and get a sense of the culture. No database captures those signals.

For what to look for on a visit, What Staffing Ratings Actually Signal gives useful context on interpreting what you observe against the staffing data.

Ask about factors the data doesn’t capture

When you tour a facility, ask directly about the things the five-star system does not measure. How are menus planned, and can residents request substitutions? What activities are available for someone with your family member’s interests and mobility? What is the staff turnover rate? How does the facility communicate with families when something changes?

A facility that answers these questions openly and specifically is telling you something the five-star system cannot.
