The Complete Guide to Holland Career Interest Test (RIASEC)
A complete guide to the Holland RIASEC test — the six interest types, how it works, how to interpret results, and find your best career match.
What Is the Holland Career Interest Test?
The Holland Occupational Themes, also known as the RIASEC model, is a career interest theory developed by American psychologist John L. Holland in 1959. After decades of research and validation, it has become one of the most widely used career assessment tools in the world.
Theoretical Background
Holland proposed that career choice is an expression of personality. People naturally gravitate toward work environments that allow them to use their abilities and express their values. When a person's interest type matches their work environment, they are more likely to experience job satisfaction and success.
The core assumptions of this theory include:
- Most people's vocational interests can be categorized into six basic types
- Work environments can also be classified by these same six types
- People actively seek career environments that match their interests
- Individual behavior results from the interaction between personality and environment
The SDS (Self-Directed Search)
In 1971, Holland developed the SDS (Self-Directed Search), the most classic Holland assessment tool. The SDS evaluates personal activity preferences, self-rated abilities, and occupational preferences to generate a three-letter Holland code that helps identify the best-matching career directions.
Today, the SDS has been translated into over 30 languages and is used in more than 100 countries worldwide.
The Six RIASEC Interest Types
RIASEC is an acronym for the six types, arranged in a hexagonal model. Adjacent types share more similarities, while opposite types are the most different.
R — Realistic
Core traits: Hands-on, practical, enjoys working with tools, machines, animals, or plants
Realistic individuals prefer concrete, tangible tasks. They are typically straightforward and like to see visible results from their work.
- Typical interests: Repairing machinery, outdoor activities, sports, crafting
- Work preferences: Structured tasks, clear procedures, tangible outcomes
- Key strengths: Mechanical operation, physical coordination, technical skills
I — Investigative
Core traits: Curious, analytical, enjoys observing and solving complex problems
Investigative individuals love exploring the unknown. They are independent thinkers who prefer using logic and data to understand the world.
- Typical interests: Scientific experiments, data analysis, research, puzzles
- Work preferences: High autonomy, intellectual challenge, deep research
- Key strengths: Logical reasoning, mathematics, scientific analysis, critical thinking
A — Artistic
Core traits: Creative, expressive, enjoys self-expression through art
Artistic individuals value freedom and individuality. They tend to be intuitive and sensitive, disliking excessive rules and structure.
- Typical interests: Drawing, music, writing, design, performing
- Work preferences: Flexible, encourages innovation, allows personal expression
- Key strengths: Creative thinking, aesthetic perception, verbal expression
S — Social
Core traits: Helpful, empathetic, enjoys interacting with and assisting others
Social individuals are skilled communicators. They care about others' needs and feelings and find fulfillment in interpersonal interactions.
- Typical interests: Volunteering, teaching, team activities, counseling
- Work preferences: Close collaboration, helping others grow, socially meaningful work
- Key strengths: Communication, empathy, teaching ability, teamwork
E — Enterprising
Core traits: Leadership-oriented, persuasive, enjoys organizing and influencing others
Enterprising individuals are energetic and goal-driven. They are good at seizing opportunities and enjoy taking risks and responsibility.
- Typical interests: Business activities, leading projects, public speaking, marketing
- Work preferences: Decision-making authority, competitive environment, advancement opportunities
- Key strengths: Leadership, persuasion, decision-making, project management
C — Conventional
Core traits: Detail-oriented, organized, enjoys working with data and information systematically
Conventional individuals are methodical and responsible. They excel at completing tasks efficiently within established frameworks.
- Typical interests: Data organization, financial management, record keeping, process optimization
- Work preferences: Clear structure, well-defined rules, stability and predictability
- Key strengths: Data processing, organizational planning, attention to detail, execution
How the Test Works: Matching Interests to Careers
The core logic of the Holland test is Person-Environment Fit.
The Hexagonal Model
The six types are arranged in the order R-I-A-S-E-C at the vertices of a regular hexagon. This arrangement is meaningful:
- Adjacent types (e.g., R and I): Highly correlated — it's common for someone to score high in both
- Alternate types (e.g., R and A): Moderately correlated
- Opposite types (e.g., R and S): Low correlation — scoring high in both is uncommon
Consistency and Differentiation
Two important concepts for interpreting results:
- Consistency: Are your top two types adjacent on the hexagon? Adjacent types indicate focused career interests
- Differentiation: Is there a large gap between your highest and lowest scores? A larger gap means clearer career direction
How to Interpret Your Results: The Three-Letter Code
After completing the Holland test, you receive a three-letter code composed of your top three scoring types. For example, "RIA" means your interests are primarily Realistic, then Investigative, then Artistic.
Interpretation Steps
- First letter: Your dominant interest type, defining your core career preference
- Combination pattern: The three letters together reveal your unique interest profile
- Match to careers: Compare your code against occupational classifications
- Consider order variations: "RIA" and "IRA" have different emphases
Common Code Combinations
| Code | Interest Profile | Typical Career Direction |
|---|---|---|
| RIA | Hands-on + Research + Creative | Architecture, Industrial Design |
| ISA | Research + Social + Artistic | Psychologist, Education Researcher |
| AES | Artistic + Enterprising + Social | Creative Director, PR Manager |
| SEC | Social + Enterprising + Conventional | HR Manager, School Administrator |
| ECS | Enterprising + Conventional + Social | Business Manager, Project Manager |
| CRI | Conventional + Realistic + Research | Quality Engineer, Data Analyst |

Holland Test vs. MBTI
The Holland test and MBTI are different but complementary assessment tools:
| Dimension | Holland Test | MBTI |
|---|---|---|
| Measures | Career interests | Personality type |
| Theory | Person-Environment Fit | Jungian Psychological Types |
| Result format | Three-letter code (e.g., RIA) | Four-letter type (e.g., INTJ) |
| Primary use | Career selection & planning | Self-awareness & relationships |
| Focus | "What do you enjoy doing?" | "What kind of person are you?" |
Better Together
- MBTI helps you understand yourself: Your thinking style, decision-making approach, energy source
- Holland helps you choose a direction: Your interests and ideal work environment
For example, an INTJ with a Holland code of IAR would likely thrive in research, technical architecture, or strategic consulting — roles requiring deep thinking and innovation.
Common MBTI-Holland Correlations
- NT Analysts (INTJ/INTP/ENTJ/ENTP) → Often I (Investigative) and E (Enterprising)
- NF Diplomats (INFJ/INFP/ENFJ/ENFP) → Often S (Social) and A (Artistic)
- SJ Sentinels (ISTJ/ISFJ/ESTJ/ESFJ) → Often C (Conventional) and S (Social)
- SP Explorers (ISTP/ISFP/ESTP/ESFP) → Often R (Realistic) and A (Artistic)
Start Your Career Exploration
Understanding your career interest type is the first step in career planning. The Holland test gives you a clearer picture of your interest preferences and helps you find matching career paths.
Remember, test results are a starting point, not a final answer. The best career choice also depends on your actual abilities, values, life goals, and other factors.
