Science of the Predictive Index®

Validity. Proven Results

Since 1955, global organizations have depended on the Predictive Index® (PI®) as a strategic assessment tool for improved employee selection, talent management, and leadership development. Our clients have confidence in PI not only because of its user-friendly accuracy but also for its scientific and research-based foundation.

The Predictive Index® (PI®) assessment was developed and validated in compliance with Equal Employment Opportunity Commission (EEOC) Guidelines, as well as the professional standards established by the American Psychological Association (APA) and the Society of Industrial & Organizational Psychology (SIOP).

PI Worldwide® remains dedicated to conducting research that ensures that the PI is work-related, free of bias, valid and reliable. Our in-house research team has amassed an extensive library of over 400 criterion-related job validity studies covering multiple jobs, industries and countries which document PI’s validity and application in the business world. For additional information on the science and validity of the Predictive Index, please contact Director of Research, Todd Harris, Ph.D. at tharris@piworldwide.com.
