Reliability and Validity

We remain committed to provide reliable, valid measurements to the business world.

Since 1955, thousands of businesses have depended on the Predictive Index for a variety of uses, including employee selection. PI Worldwide remains dedicated to conducting research that ensures that the PI is work-related, free of bias, valid and reliable.

Clients around the world have expressed confidence in the Predictive Index, both for its repeatable accuracy and for its scientific and research-based foundation.

The Predictive Index 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).

We have amassed an extensive library of over 400 criterion-related job validity studies covering multiple jobs, industries and countries. These document the instrument's validity and usefulness in the business world.
