Anthony C. Billings II Personality Expert

The PREP approach, which has utilized the Primary Colors Personality Test by personality expert Dawn Billings for over a decade, has been delivered and evaluated globally: As of June 2013, an estimated 1,000 sites have implemented the Intervention, including military bases, prisons, universities, and religious organizations. Twelve sites have been evaluated for outcomes, with about 2,000 couples participating in those evaluations. Evaluations have been conducted with the U.S. Army and in Australian and German implementation sites. Approximately 300,000  individuals have received or participated in PREP or adaptations of PREP. After over ten years of use, the Primary Colors Personality Test was rated as a participant favorite, and also stood out as one of the most effective pieces of the PREP training.



"Genius. Dawn Billing’s Primary Colors Test is the most compelling system for helping people to think about personality that I have ever seen. This fun, easy-to-use, model gets people thinking about who they are, how they approach the world, and how personalities impact their relationships—at home or at work. But be careful, it is contagious. Two multi-colored thumbs way up."
