The Certification
Our rigorous 12-step company certification process is the most reliable anywhere. We survey a large, random sample of REAL customers by telephone to get the most accurate rating and verify only actual customers are responding. By surveying from a company’s entire customer base, we ensure the results of our study, good or bad, truly represent the company’s customer satisfaction level. All responses for each Diamond Certified company are displayed on its Diamond Certified Company Report page.
Each respondent is identified by first name and last initial to protect their privacy. If a response is overtly negative or a respondent’s first name is easily identifiable because of uniqueness (either due to its rare use in American society or because of small respondent sample sizes), the name will be altered using a strict formula. This is to protect the anonymity of the respondent while including their feedback for other consumers to review.
Companies must score Highest in Quality and Helpful Expertise® (a 90+ on a 100 scale) and pass all our credential-based ratings to earn Diamond Certified. Only the Best Pass the Test™. By requiring such a high score to qualify, we cut out mediocre and poorly performing companies. We then conduct ongoing research and ratings to ensure all companies maintain their high performances.
