Holland Code (RIASEC) Career Test

What is the Holland Code?

The Holland Code (also known as RIASEC) is a theory of vocational interests developed by psychologist John L. Holland in the 1950s. It classifies interests into six types: Realistic, Investigative, Artistic, Social, Enterprising, and Conventional. Your combination of the three highest-scoring types forms your unique Holland Code, which can be used to identify careers, educational paths, and work environments that match your interests.

What are the six RIASEC types?

• Realistic: working with tools, machines, technology, and physical environments. Often suited to trades, engineering, agriculture, and technical fields.
• Investigative: science, analysis, research, and abstract problem-solving. Often suited to research, medicine, mathematics, and data analysis.
• Artistic: creative expression through writing, music, design, and performance. Often suited to arts, media, design, and communications.
• Social: helping, teaching, counseling, and supporting others. Often suited to education, healthcare, social work, and community roles.
• Enterprising: leadership, business, persuasion, and sales. Often suited to management, entrepreneurship, law, and marketing.
• Conventional: data management, organization, record-keeping, and structured procedures. Often suited to finance, administration, logistics, and operations.

What is the O*NET Interest Profiler?

The O*NET Interest Profiler Short Form is a 60-item vocational interest instrument developed by the National Center for O*NET Development and funded by the US Department of Labor. It assesses the six Holland types using standardized work activity items and has strong reliability, with Cronbach alpha coefficients between 0.87 and 0.94 across the six scales in the standardization study by Rounds and colleagues (2010). The instrument is a public domain work product of the US federal government.

How do I use my Holland Code for career exploration?

Your Holland Code represents the three interest types where you scored highest. Look for careers and work environments where the daily tasks, required skills, and organizational culture align with your top types. The order of the letters matters: the first letter represents your strongest interest area. You can also use your code to evaluate whether a potential role or workplace feels like a natural fit rather than a compromise.

How accurate is this test?

The O*NET Interest Profiler Short Form has strong reliability, with internal consistency (Cronbach alpha) between 0.87 and 0.94 across the six scales. Results are most accurate when you answer based on genuine reactions to the activity descriptions, not on what you think you should like or what you have experience doing. Your score reflects your interests, not your skills or current abilities.

Is my data stored anywhere?

No. OmConscious has a strong commitment to user privacy and does not collect any personal data. All scoring happens entirely in your browser using JavaScript. Your answers are never transmitted to any server, stored in a database, or shared with any third party. No account or login is required, and results are available instantly. When you close the tab, your answers are gone.

Can interests change over time?

Yes. Vocational interests are relatively stable in adulthood but can shift with education, experience, and life transitions. Research suggests that broad interest patterns tend to remain consistent, but specific preferences and rankings can change. Retesting every few years can be useful, particularly after significant career changes or new educational experiences.
