Psychologist John Holland proposed that people and work environments can be grouped into six broad types. Known as RIASEC, it is one of the most widely used career frameworks in the world.
The six types
- Realistic — hands-on, practical, prefers tools, machines, and nature.
- Investigative — analytical, curious, enjoys research and problem-solving.
- Artistic — creative, expressive, values originality.
- Social — cooperative, supportive, drawn to helping and teaching.
- Enterprising — persuasive, ambitious, interested in leadership and sales.
- Conventional — organized, detail-oriented, comfortable with data and systems.
How codes combine
Few people fit only one type. Most have a three-letter code, such as SIA or RCE, describing their strongest preferences. The closer a career matches your code, the more likely you are to feel engaged.
How to use the model
Use your code to explore career clusters and majors. It is a map, not a verdict. Combine it with aptitude and personality data for a fuller picture.
