*The above represent the key validations and reviews conducted by and for the psychometric and legal specialists within client companies. The results, while theoretically rigorous, are also targeted toward actual organizational usage. Since they involve internal data, privacy concerns require that the studies remain proprietary. There have been numerous tests done on original Hartman material as well. These are available on request.
