The document provides summaries of several case studies that demonstrate the return on investment from using the EQ-i emotional intelligence assessment tool. The case studies show that the EQ-i can predict characteristics of high performers and is useful for selection, training, development and coaching. Specifically, the EQ-i identifies emotional intelligence skills that differentiate top performers and relates these skills to increased sales, performance, customer satisfaction, and decreased attrition and training costs. The documented organizations that achieved measurable performance improvements include American Express, the US Air Force, New Zealand Telecom, a debt collection agency, and CIBC.
