About TableGrade
TableGrade makes Clark County restaurant inspection data easier to find and understand. Inspection records are pulled directly from Clark County Public Health and updated nightly.
How scoring works
Each inspection assigns points for violations found. Higher points mean more serious problems. Violations are classified as red (high risk, directly linked to foodborne illness) or blue (lower risk, related to facility conditions or food handling practices).
| Score range | Rating | What it means |
|---|---|---|
| 0-9 | Clean | No significant violations found. |
| 10-39 | Minor | Low-risk violations noted. Corrective action expected at next inspection. |
| 40-64 | Significant | Violations pose a potential health risk. A follow-up inspection is typically required. |
| 65-99 | Severe | Serious violations found. Immediate corrective action required; closure may be ordered. |
| 100+ | Closed | Facility was ordered to close. It may reopen after passing a follow-up inspection. |
How letter grades work
Each facility gets a letter grade from A to F. The grade reflects both how a facility does on its own terms and how it compares to similar facilities in Clark County. It is computed over a rolling 12-month window and updated nightly.
The grade is a blend of two components:
Absolute performance (60%)
This part of the grade looks at the facility's average inspection score over the past year, regardless of how anyone else is doing. Lower average scores earn more points. A facility with very few violations most of the time does well here even if its peers are worse.
| Average score (past 12 months) | Points earned (out of 100) |
|---|---|
| 0-5 | 100 |
| 6-15 | 80 |
| 16-39 | 60 |
| 40-64 | 35 |
| 65-99 | 15 |
| 100+ | 0 |
How you compare (40%)
This part compares the facility to others in the same permit category (restaurants vs. restaurants, food trucks vs. food trucks, and so on) over the same 12-month window. A facility scoring an average of 18 points might be doing quite well if most restaurants in the county average 30 points, or doing poorly if most average 10. The comparison adjusts for the real baseline of each category rather than applying a single county-wide yardstick.
Facilities ranked at the top of their category earn close to 100 points on this component; those at the bottom earn close to 0. The two components are then combined: 60% absolute + 40% comparative = blended score.
Trajectory
If the three most recent inspections suggest the facility is moving into a worse severity band, the blended score is reduced by 5 points. If the trajectory points toward a better severity band and the most recent score is already there, the blended score increases by 5 points. A facility trending steadily in one direction gets credit (or a penalty) even if its current snapshot looks average. This modifier is small enough that it won't flip a letter grade on its own, but it rewards sustained improvement and flags facilities that are heading in the wrong direction.
Automatic overrides
Some outcomes override the formula entirely:
- Any closure in the past 12 months results in an automatic F, regardless of what the blended score would otherwise be.
- Any follow-up inspection required in the past 12 months caps the grade at D+. A facility can still earn a D+ even with a strong blended score if a follow-up was triggered.
Letter grade scale
The blended score (0-100) maps to letter grades as follows. The bands are deliberately wider than a standard academic scale because most facilities cluster in the middle of the range, and narrower bands would compress everyone into C and D grades, stripping the letters of useful signal.
| Blended score | Grade |
|---|---|
| 95-100 | A |
| 90-94 | A- |
| 85-89 | B+ |
| 80-84 | B |
| 75-79 | B- |
| 68-74 | C+ |
| 61-67 | C |
| 55-60 | C- |
| 48-54 | D+ |
| 41-47 | D |
| 35-40 | D- |
| 0-34 | F |
When grades update
Grades are recalculated nightly after new inspection data is scraped. Because the comparative component requires ranking every facility against its peers, grades are precomputed and stored rather than calculated on demand. A grade reflects the facility's 12-month record as of the most recent nightly run, typically within 24-48 hours of a new inspection appearing on the county's site.
Facilities with no inspections in the past 12 months do not receive a letter grade.
Data coverage
Records go back to January 2023, when Clark County launched their current inspection system. Approximately 1,765 permitted food facilities are tracked across Vancouver and Clark County.
Accuracy
Records may reflect a 24-48 hour delay from the time of inspection. Clark County Public Health makes no warranty as to the accuracy of this data. TableGrade is an independent site and is not affiliated with Clark County.
