PeoplePerHour's vetting process is quite different from that of other freelance sites. PeoplePerHour uses a scoring algorithm called CERT (Content, Engagement, Repeat Usage, Trust) to determine a freelancer's experience, competence, and trustworthiness. The system automatically rates freelancers from 1 to 5 based on their skills, response speed, number of completed jobs, performance, and reliability. A rating of 5 means high performance has been achieved by consistently delivering high-quality work.
