Holland codes explained: find work that fits your interests

The point is fit. People tend to be happier and stay longer in work that matches what they are actually interested in, not just what they are good at. To get your own code, take the career interest test.

The model comes from Holland's interest research, which noticed that people and jobs both fall into recognisable interest patterns. A job has a code, based on the activities it involves day to day. You have a code, based on the activities you enjoy. The closer the two match, the more the work feels like yours.

It is one of the most widely used models in careers guidance, because it is simple, practical and it asks the right question: not "what are you capable of?" but "what would you happily spend a Tuesday afternoon doing?"

• Realistic (R): the makers. You like working with your hands, tools, machines, plants or animals. You would rather fix the bike than read about fixing it. Think engineering, trades, farming, outdoor work. More on Realistic.
• Investigative (I): the thinkers. You like puzzles, data and figuring out why. You read the instructions and then the footnotes. Think science, research, medicine, analysis. More on Investigative.
• Artistic (A): the creators. You like making something new and expressing yourself. Rules feel like a starting point. Think design, writing, music, performance. More on Artistic.
• Social (S): the helpers. You like teaching, caring and supporting people. You are the one everyone brings their problems to. Think teaching, nursing, counselling, community work. More on Social.
• Enterprising (E): the persuaders. You like leading, selling and making things happen. You see a room and want to win it. Think business, sales, management, law, politics. More on Enterprising.
• Conventional (C): the organisers. You like order, systems and getting details right. A tidy spreadsheet is a quiet pleasure. Think finance, administration, logistics, data. More on Conventional.

Your first letter is your strongest pull. The second and third shape how it plays out.

Take two people who both lead with Social. An SAE might thrive running creative workshops or teaching drama, where helping meets self-expression and a bit of showmanship. An SCI might thrive in a well-run clinic or a school office, where helping meets order and careful thinking. Same first letter, very different days.

The six types also sit around a hexagon in the order R, I, A, S, E, C. Neighbours on the hexagon, such as Investigative and Artistic, have a lot in common. Opposites, such as Artistic and Conventional, pull in different directions. If your top letters are neighbours, your code is tightly focused. If they sit far apart, you have range, and the best fit is often a role that combines both.

Our career interest test is our own questionnaire, built on Holland's interest model. You rate forty-eight activities by how much you would enjoy them, which takes about seven minutes. Each of the six interests is scored from eight of those activities, and your code is your top three.

We then match your full pattern of six scores against the interest profiles of a large set of real occupations, and show you the closest matches. Each type also has its own page, and every three-letter code has a page of jobs that share it.

If all six of your scores come out close together, we tell you it is a flat profile. That usually means one of two things: you are genuinely interested in a lot, or you are not yet sure what you enjoy. Either way, the job list is a place to explore rather than a ranking to trust to the decimal point.

A code is most useful as a filter and a conversation starter.

• Use it to widen your list. Look at the matched jobs and pick three you had never considered. Read what people in them do all day.
• Check the day, not the title. A job's code is about daily activities. A Social person in a role that is mostly spreadsheets will feel it, whatever the title says.
• Look for the blend. If your code is IAS, the best roles mix ideas, creativity and people: user research, science communication, teaching design.
• Use it in your current job. You may not need a new career. Swapping one task, volunteering for one project, or shaping your role towards your top letter can change how work feels.
• Talk it through. Share your code with a mentor, careers adviser or a friend who knows you well. "I'm EAS" opens a better conversation than "I don't know what to do".

Your code tells you what draws you. It does not tell you how you work or what matters most to you. For that, pair it with the work style quiz, which shows how you like to work with people and pace, and the personal values test, which shows what you need work to give you.

Interest, style and values together make a very clear picture. When you are ready, take the career interest test and get your code.
