The O*NET Interest Profiler, facilitated by My Next Move, is supported by the U.S. Department of Labor's Employment & Training Administration. It comprises 60 questions regarding work-related activities. Your objective is to carefully read each question and determine your inclination towards that type of work on a scale ranging from "strongly dislike" to "strongly like." 

Truity's website provides various free career tests grounded in the Holland Code and Big Five systems. Alongside the Career Personality Profiler, Truity offers a TypeFinder® for Career Planning test, a Holland Code Career Test, and a Photo Career Quiz. The Career Personality Profiler stands out as the most comprehensive among Truity's four tests. Similar to My Next Move's O*NET Interest Profiler, this test involves reading statements about job activities and expressing your preference or aversion to performing that work. Additionally, you'll assess statements related to personality traits and indicate the extent to which they align with your characteristics.
