In 2004 the Evaluation Center at Western Michigan University, a group that specializes in the evaluation of assessment instruments, reviewed all existing Executive Intelligence (ExI) Evaluation questions and their corresponding answer keys, as well as the empirical findings collected to date.  Led by Management Professor Jennifer Palthe, the group concluded:

"A review and examination of material and data associated with the ExI Evaluation suggest that this instrument has significant potential as a managerial assessment tool.  It is evident that it measures what it purports to measure and captures aspects of real-time managerial performance that other instruments are unable to capture.  The ExI Evaluation clearly has construct, content, convergent, and face validity; its internal reliability reflects its dependability and precision as a measuring instrument; and initial evidence suggests strong criterion-related (concurrent) validity.  Its ability to capture a manager’s ability to reason deductively, to evaluate arguments, and to understand meaning provides practitioners with a tool that can adequately identify potentially exceptional managerial performers.  Furthermore, the instrument’s practical relevance and ease-of-scoring makes it highly attractive as a superior, contemporary managerial assessment tool."

To date, Executive Intelligence interviews have been administered to over 1200 senior executives in nine different countries and in seven different languages.   Neither language, country of origin, gender, nor race has demonstrated any influence on testing performance.
