How scores are calculated
The calculation is deliberately plain. Nothing is weighted by popularity, and no score is boosted or suppressed by us.
The criterion average
- Each evaluation rates nine criteria from 1 to 5.
- A company's score for a criterion is the unweighted mean of every published evaluation for that criterion.
- Scores are shown to one decimal place, and are not rounded up.
The overall score
- The overall score is the mean of the nine criterion averages, so no single criterion dominates.
- It is never shown without the number of evaluations behind it.
- A company with fewer than three published evaluations shows the individual reviews but no overall score.
Recency
- The last-12-months figure is calculated from evaluations posted in the previous twelve months only.
- The trend chart shows six-month averages so that a company's direction is visible, not only its position.
- Older evaluations are kept and remain readable; they are never silently deleted.
What we do not do
- We do not rank companies against each other or publish leaderboards.
- We do not allow a company to pay for a higher position, a removed review, or a hidden score.
- We do not estimate scores for criteria a contributor did not rate.
