The score runs from 0 to 10. It’s a weighted average of five factors plus Workplace (10% when at least 20 employee reviews are on file), each scored only from verified, sourced facts about a company’s Pacific Northwest operation, adjusted for regional review scale, multi-source verification depth and state breadth. Missing data never counts for or against a company: a factor with no usable inputs is left out and the other weights are scaled up. That applies to 3 ranked companies today.
