The Plum Discovery Survey is based on the Big Five Personality Model, a well-regarded and highly researched framework. This is the most widely accepted framework for personality and for use as a predictor of job performance. Since the creation of The Plum Discovery Survey, it has undergone rigorous testing to establish test-retest reliability, convergent validity, and criterion-related validity.
We leverage deep expertise in industrial/organizational psychology to develop our surveys and supplementary materials. It is of utmost concern that every tool we develop is based on the latest research.
