How this home got 3 stars
The overall rating isn't an average. CMS starts from the inspection rating and nudges it at most two steps. Here is the arithmetic for this home, using CMS's own rules.
-
Health inspections
★★★★★starting point
Everything starts from what state inspectors found on site. This is a ranking against other homes in California.
-
Staffing
★★★★★no change
Only a 5-star staffing rating adds a star, and only a 1-star rating removes one. Ratings of 2 to 4 change nothing.
-
Quality measures
★★★★★no change
Same rule: 5 stars adds one, 1 star takes one away. These measures are mostly reported by the home itself.
-
Overall
★★★★★3 of 5
Matches the rating CMS publishes on Care Compare.

Where it sits among California homes
Diamond Ridge Healthcare Center carries 82 inspection points. That is fewer than 53% of California's 1,154 rated homes.
Inspectors' citations earn points by how serious and how widespread they were (the grid below). CMS then ranks every home in California: the 10% with the fewest points get 5 stars, the 20% with the most get 1 star, and the middle 70% split evenly into 2, 3 and 4.
- 5★ 0–33 pts
- 4★ 33–66 pts
- 3★ 66–96 pts
- 2★ 96–146 pts
- 1★ over 146 pts
Bars show every rated home in California by its weighted inspection score. CMS recalibrates the cut points monthly but holds a home's rating until its own score changes, so a home can sit just outside today's band.

What inspectors found
46 health citations on record since 2019. Each one gets a letter: the row says how badly residents were affected, the column how many.
Immediate jeopardyResidents at risk of serious injury or death
Actual harmA resident was hurt
Potential for harmNo one was hurt, but could have been
Minimal harmPaperwork-level problems
Read the rows, not the total. Most citations nationwide are a D: one problem, nobody hurt. Rows G–I mean a resident was harmed; J–L mean inspectors found residents in immediate danger of serious injury or death.
Small numbers in each cell are the inspection points CMS assigns per citation. Those points are what the state curve above ranks.
No citation on record at the harm or immediate-jeopardy level.
