The Holland Code (RIASEC) Explained: 6 Career Interest Types

Choosing a career is easier when you know what kind of work actually interests you. The Holland Code is one of the most widely used tools for exactly that. It sorts work interests into six types (Realistic, Investigative, Artistic, Social, Enterprising and Conventional), often shortened to RIASEC. This guide explains each of the six types in plain English, shows real jobs that fit each one, explains how to read your three-letter code, and covers what the research says about how well interests predict career happiness.

What is the Holland Code?

The Holland Code comes from the work of American psychologist John L. Holland, who developed his theory of career choice from the late 1950s onward. His best-known book on the topic, Making Vocational Choices, was first published in 1973.

Holland's big idea was simple but powerful:

• People can be described by a mix of six interest types.
• Work environments can be described by the same six types.
• People tend to be happier and more likely to stay in jobs when their interests match their environment. Holland called this match congruence.

For example, someone who loves research and solving puzzles will probably enjoy a lab or a data team more than a sales floor, and the reverse is true for someone who loves persuading people.

Today the RIASEC model is everywhere in career guidance. Holland's own Self-Directed Search questionnaire is built on it, the Strong Interest Inventory uses the six types as its broad themes, and the U.S. Department of Labor's O*NET career database lists an interest profile for hundreds of jobs using the same six letters.

The 6 Holland Code types at a glance

On our career interest test, we give each type a friendly name. Here's how they line up:

Now let's look at each type in more depth.

Realistic: the Doer

Realistic people like practical, hands-on work where they can see real results. They often enjoy tools, machines, building, cooking, outdoor work or working with animals. They usually prefer doing to discussing.

Careers to explore: scientist, data analyst, doctor, software engineer, economist, psychologist, pharmacist, researcher.

Artistic: the Creator

How to read your three-letter Holland Code

Very few people are just one type. Most career tools describe you with a three-letter code, made of your three strongest interests in order. For example:

• SAE might describe someone who loves helping people, enjoys creativity and is comfortable leading: think teacher, counselor or nonprofit leader.
• IRC might describe someone who loves analysis, enjoys hands-on technical work and likes order: think engineer, lab technician or IT specialist.
• ECS might describe someone who enjoys leading, organizing and working with people: think operations manager or HR manager.

Your first letter matters most, but the second and third add a lot. Two people with the same first letter can enjoy very different jobs.

The Holland hexagon

Holland arranged the six types around a hexagon in this order: R – I – A – S – E – C, then back to R. Types next to each other are the most similar; types across from each other are the most different:

• Neighbors (like Investigative and Artistic, or Social and Enterprising) share a lot, so codes like IA or SE feel natural.
• Opposites are Realistic and Social, Investigative and Enterprising, and Artistic and Conventional. A code that mixes opposites isn't wrong. It just suggests varied interests, and you may enjoy roles that combine different kinds of work.

Flat or peaked profiles

If one or two of your scores clearly stand out, you have a peaked profile, which usually points to a clear direction. If all six scores are similar, you have a flat profile. That can mean you're open to many paths, or that you haven't had a chance to try many kinds of work yet. Real experience, like volunteering or internships, can help.

How interests differ from personality and skills

It's easy to mix these up:

• Interests (what the Holland Code measures) are about what you enjoy.
• Skills are about what you're good at. You can enjoy something you haven't learned yet.
• Personality traits, like those in the Big Five personality traits, describe how you usually think, feel and behave.

They're related. For example, research finds that people high in openness to experience often score high on Artistic and Investigative interests, and extraverts often lean toward Enterprising and Social. But they aren't the same thing. A great career choice usually considers all three, plus your values, like stability, creativity or helping others.

If you're curious how motivation fits in too, our article on the best careers for each Enneagram type looks at work through the lens of core motivations. And if you know you're on the quiet side, see our list of the best jobs for introverts.

Does the Holland Code actually work?

The Holland model is one of the most researched ideas in career psychology. Here's what the evidence broadly shows:

• The six types hold up. Studies in many countries find the same six interest areas, though the perfect hexagon shape fits some groups better than others.
• Interests are fairly stable. Career interests tend to be quite consistent from late adolescence into adulthood, though they can shift with experience.
• Fit matters, modestly. Matching your interests to your work is linked to somewhat higher job satisfaction and performance, and to staying longer in a field. The effects are real but not huge, because pay, colleagues, managers and life circumstances matter too.

In other words, the Holland Code is a useful compass, not a crystal ball. It points you toward areas worth exploring, but it can't tell you which single job will make you happy.

How to use your Holland Code

1. Find your top three letters. Take an interest test and note your strongest areas.
2. Explore jobs that match. Career databases like O*NET let you browse jobs by interest code. Look for roles that combine your top two or three letters.
3. Talk to people in those jobs. A 20-minute chat with someone in the field tells you more than any list.
4. Test it in real life. Try a short course, a volunteer role, a side project or an internship.
5. Weigh your skills and values. Interests open doors; skills, values and circumstances help you choose which one to walk through.
6. Revisit it over time. Your interests can grow as you try new things.

Key takeaways

• The Holland Code describes work interests with six types: Realistic, Investigative, Artistic, Social, Enterprising and Conventional (RIASEC).
• Most people are a mix, described by a three-letter code of their strongest interests.
• Neighboring types on the hexagon are similar; opposite types are very different.
• Matching interests to work is linked to somewhat higher satisfaction and performance, but it's not the only thing that matters.
• A career interest test is a starting point for self-reflection and exploration, not professional career advice or a diagnosis.
