Because the use of assessment center testing is a human resource tool that incorporates work simulation into a methodology that best illustrates a candidate's performance once a position has been achieved, these processes have been increasing regularly in popularity. Hence, this book provides the background evolution and the rationale needed by law enforcement to actively participate in this area.
