How we grade nursing homes
What data goes into a grade?
CMS Care Compare: Nurse staffing (30), Health inspections (30), Quality measures (25), Penalties (15). Each metric is percentile-ranked against California facilities in the same size band; A ≥ 72, B ≥ 58, C ≥ 42, D ≥ 28, F below. Facilities with under 60% of data are shown as "Not graded".
Can a facility pay to improve its grade?
No. Grades are computed from public data and have no editable field. Nothing on this page is sponsored.
Is a grade a substitute for visiting?
No. Use it to shortlist, then visit, ask for the latest inspection report, and talk to residents' families.
