Robert and Joyce Hogan have developed a suite of 4 assessment tools, including one ability test and 3 personality inventories. The best known of their assessment tools is the Hogan Personality Inventory (HPI).
The HPI is based on a Five Factor Model of personality. It provides information on the “bright side” of personality that is characteristics that appear in social interaction and that can facilitate or inhibit a person’s ability to get along with others and to achieve their goals.
In addition to the HPI, Hogan’s have developed the Hogan Development Survey (HDS) which is a measure of the “dark side” of leadership behaviours and derailers and the Hogan Motives Values and Preferences Inventory (MVPI).
