The document discusses the three main factors that drive the effectiveness of employment background screening - accuracy, turnaround time, and cost. It explains that accuracy depends on the quality of researchers, data, and screening company practices. Turnaround time is influenced by the complexity of a candidate's history and number of checks. Cost is driven by similar factors as turnaround time as well as data source charges. An ideal screening provider achieves the "trifecta" of accuracy, speed and low cost through technology, transparency, an experienced team, comprehensive services, and industry accreditation.
