A rater is a person who conducts tests, gathers data, and determines a rating for specific applications. They are often responsible for measuring and evaluating quality to improve the systems and processes of a company. For example, Google ad quality raters work from home and check facts to improve Google’s ranking algorithm. Home field raters are responsible for assessing the safety of new residential construction and testing environments to provide a home energy rating and ensure code compliance and compliance with green programs. Other rater positions include insurance raters, energy raters, HERs raters, and rater managers, who overview clinical rating departments.
