The Predictive Index® Tests

History of The Predictive Index®

Arnold Daniels was introduced to personality and talent assessments during his time in the U.S. Army Air Corps.  After his time in the Army, Arnold continued his education at Harvard Business School – learning about the development of statistically valid assessments.  He then authored The Predictive Index Behavioural Assessment™ in 1952 and founded The Predictive Index® in 1955.  The PI Behavioural Assessment is now used by thousands of clients globally and is available in 70 languages.

Science of The Predictive Index®

The Predictive Index Behavioural Assessment™ was created through a normative sample of thousands of people.  Through the data, a normal range of behavioural factor levels for the adult working population was identified.

The Predictive Index Cognitive Assessment™ is a 12 minute timed assessment that indicates an individual’s capacity to catch on quickly, adapt to change, understand complex tasks and make strategic decisions. General cognitive ability has been shown to be best single predictor of success in job training and performance, particularly in complex roles.

Built to the standards of: Equal Employment Opportunity Commission, Society for Industrial and Organizational Psychology, International Test Commission and The American Psychological Association

Nearly 500 criterion-related validity studies completed across industries
