Research shows that, within individuals, personality is relatively stable. Although an individual’s scores may fluctuate slightly over time, significant shifts in HPI and HDS scores are rare and may result from careless responding or increased self-awareness about Hogan scores. Because personality is stable, and because Hogan maintains norms to reflect current functioning, individuals need not re-take inventories.
Although retesting is generally unnecessary from the standpoint of accuracy of results, some organizations choose to implement a retest policy based on situational variables that are specific to their assessment application. Contact your Hogan representative for further information.
