This study determined the Holland code of members of the National Organization for Human Services. The authors used the O*NET Interest Profiler–Short Form to find that a sample of 355 human services professionals had a Holland code of Social Artistic, with Investigative, Enterprising, and Conventional codes significantly lower than Artisitc. Demographic differences were not found based on gender, whether participants identified human services as their primary field, or whether they had formal education in human services. Slight differences based on age were noted. Results will be used to advocate for inclusion of “human services professional” in the Standard Occupational Classification system.
