Ever wondered what really drives you to get up and tackle your day? Sometimes work feels like just a way to pay the bills, but it can actually be a meaningful extension of who you are. American psychologist Dr. John Holland figured this out back in the 1950s. He developed a groundbreaking theory that your success and satisfaction in a career depend heavily on how well it matches your personality. If you pick a job that aligns with your core interests, it feels less like a grind, and even the workplace vibe clicks better. His model is famously represented as a hexagon with six personality types: Realistic, Investigative, Artistic, Social, Enterprising, and Conventional. Each type connects to specific career paths and work environments, and this simple inventory will help you see which ones suit you best.

Holland’s core idea is that people thrive in work environments that fit their personalities. For example, if you are a Realistic type who loves tinkering with tools, a desk job crunching numbers as a Conventional type might feel draining and unfulfilling. His model, often called the RIASEC model, became a cornerstone for career counseling worldwide. A fascinating aspect is its hexagonal structure, which shows the relationships between the types. Adjacent types on the hexagon (like Realistic and Investigative) share common interests and often blend well together in a career. Conversely, opposite types on the hexagon (like Artistic and Conventional) have conflicting interests and rarely mix well. Research consistently backs this up—people who choose careers that match their Holland Code tend to report higher job satisfaction and stick with their jobs longer. The beauty of this approach is that it’s not about what you’re good at; it’s about discovering what truly sparks your interest.

Take the Career Interest Inventory

This inventory is simple: you’ll see 30 pairs of careers. For each pair, pick the one that feels closer to your personal interests. Don't base your choice on salary, prestige, or what others expect of you. Instead, ask yourself, “Which of these sounds more interesting? Which one would I actually enjoy trying?” Note your choice for each pair. You will tally your answers later to find your personal code.

1. Engineer (Realistic) or Biologist (Investigative)
2. Mechanic (Realistic) or Physicist (Investigative)
3. Carpenter (Realistic) or Musician (Artistic)
4. Farmer (Realistic) or Photographer (Artistic)
5. Electrician (Realistic) or Teacher (Social)
6. Dentist (Realistic) or Counselor (Social)
7. Pilot (Realistic) or Manager (Enterprising)
8. Construction Worker (Realistic) or Politician (Enterprising)
9. Mechanic (Realistic) or Accountant (Conventional)
10. Plumber (Realistic) or Archivist (Conventional)
11. Chemist (Investigative) or Designer (Artistic)
12. Architect (Investigative) or Writer (Artistic)
13. Mathematician (Investigative) or Social Worker (Social)
14. Researcher (Investigative) or Nurse (Social)
15. Programmer (Investigative) or Salesperson (Enterprising)
16. Economist (Investigative) or Marketer (Enterprising)
17. Biologist (Investigative) or Auditor (Conventional)
18. Physicist (Investigative) or Data Analyst (Conventional)
19. Artist (Artistic) or Teacher (Social)
20. Actor (Artistic) or Psychologist (Social)
21. Writer (Artistic) or Lawyer (Enterprising)
22. Director (Artistic) or Entrepreneur (Enterprising)
23. Musician (Artistic) or Secretary (Conventional)
24. Designer (Artistic) or Banker (Conventional)
25. Consultant (Social) or Entrepreneur (Enterprising)
26. Counselor (Social) or Salesperson (Enterprising)
27. Social Worker (Social) or Banker (Conventional)
28. Teacher (Social) or Auditor (Conventional)
29. Manager (Enterprising) or Accountant (Conventional)
30. Politician (Enterprising) or Secretary (Conventional)

How to Score Your Results

Now, tally your choices for each of the six types. Count how many times you chose a career labeled with R (Realistic), I (Investigative), A (Artistic), S (Social), E (Enterprising), and C (Conventional). Each type will have a score from 0 to 10. Your highest scores indicate your dominant personality types. Focus on your top two or three types. Your personal "Holland Code" is the first letter of your top types, written in order from highest to lowest score. For example, if you scored highest in Social, followed by Artistic and then Enterprising, your code would be SAE.

Understanding Your Holland Code

Your code provides a powerful lens through which to view your career path. A single dominant type points to a clear preference, but most people are a combination of two or three types, which opens up even more career possibilities.

• Realistic (R) - The Doers: You prefer hands-on work with tools, machines, plants, or animals. You are practical, stable, and enjoy building, fixing, or growing things.
  • Careers: Mechanic, Pilot, Engineer, Dentist, Farmer, Electrician, Carpenter.
  • Neighbors on Hexagon: Investigative (I) and Conventional (C).
• Investigative (I) - The Thinkers: You love to observe, analyze, and solve complex problems. You are curious, precise, and drawn to science, math, and research. You enjoy working with ideas and data more than people.
  • Careers: Programmer, Biologist, Architect, Mathematician, Chemist, Physicist, Researcher.
  • Neighbors on Hexagon: Realistic (R) and Artistic (A).
• Artistic (A) - The Creators: You are imaginative, expressive, and crave originality. You enjoy unstructured activities that allow you to use your creativity and intuition. You thrive when you can create new things, whether in writing, performance, or visual arts.
  • Careers: Designer, Photographer, Director, Writer, Artist, Musician, Actor.
  • Neighbors on Hexagon: Investigative (I) and Social (S).
• Social (S) - The Helpers: You are energized by helping, teaching, and connecting with other people. You are empathetic, cooperative, and skilled at communicating. You find fulfillment in healing, developing, or empowering others.
  • Careers: Psychologist, Teacher, Doctor, Nurse, Social Worker, Counselor, Consultant.
  • Neighbors on Hexagon: Artistic (A) and Enterprising (E).
• Enterprising (E) - The Persuaders: You are a natural leader who enjoys influencing, persuading, and managing others to achieve goals. You are ambitious, energetic, and thrive in competitive environments where you can take risks and lead projects.
  • Careers: Entrepreneur, Marketer, Lawyer, Manager, Politician, Salesperson.
  • Neighbors on Hexagon: Social (S) and Conventional (C).
• Conventional (C) - The Organizers: You are organized, detail-oriented, and value structure and precision. You enjoy working with data, following clear procedures, and maintaining order. You are reliable and efficient in predictable environments.
  • Careers: Accountant, Economist, Secretary, Auditor, Archivist, Banker, Data Analyst.
  • Neighbors on Hexagon: Enterprising (E) and Realistic (R).

Your Holland Code, such as 'ASE', can point you toward careers that blend those types—for instance, an Art Gallery Manager (Artistic, Social, Enterprising). This test is not a final verdict on your future, but rather a powerful nudge to explore career paths that feel right for you. If you want to dig deeper, reflect on your specific strengths, talk to people in fields that interest you, or chat with a career counselor. Hopefully, this opens a new and exciting perspective on your professional journey!
