The Core Values Index (CVI)
It is the most reliable assessment ever created in revealing the unchanging nature of an individual.
It characterizes and quantifies what Abraham Maslow called the unchanging innate nature of a person that inscribes where a person can make their highest and most productive contribution to the world.
Repeat score reliability is the measurement of how much an assessment stays the same over time. The CVI has proven in (longitudinal studies) to have the highest at over 94%. It provides a clear and useful picture of the innate, unchanging nature of an individual. This is much different than personality and behavioral assessments.
