My Holland Code

According to Dr. John Holland’s theory of careers and vocational choices, known as Holland Codes, my personality type is that of an ICASER.

The Origin

There are things that you enjoy doing, whatever the industry or job title. The key to finding a satisfying career is to match your fundamental interests with occupations.

For instance, a Social person would go crazy sitting alone in an office all day. Or if you are Artistic, you would probably hate having to conform to a set of strict rules in your job. That is why career and vocational tests can be so helpful.

According to Dr. John Holland‘s theory of careers and vocational choices, known as Holland Codes, there are six personality types: Realistic, Investigative, Artistic, Social, Enterprising and Conventional.

Test Yourself

Out of the various tests out there, this is one you may want to try.

Test Instructions: The test consists of 48 tasks that you will have to rate by how much you would enjoy performing each on a scale of (1) dislike (2) slightly dislike (3) neither like not dislike (4) slightly enjoy (5) enjoy. The test will take most five to ten minutes to complete.

Participation: This test is provided for educational and entertainment use only. It should not be used as psychological advice of any kind and comes without any guarantee of accuracy or fitness for any particular purpose. Also, your responses may be recorded and anonymously used for research or otherwise distributed.

Eric’s Score

Eric’s ‘personal Holland Code is that of an ICASER

I → Like to work with DATA.
C → Like to work with DATA.
A → Like to work with IDEAS and THINGS.

S → Like to work with PEOPLE.
E → Like to work with PEOPLE and DATA.
R → Like to work with THINGS.


The list of suggested occupations for Eric includes some interesting hints. Potential professional challenges fitting his profile may be found here.

These suggested choices are based upon the information in the Occupational Information Network (O*NET). The O*NET is a free online database that contains hundreds of occupational definitions to help students, job seekers, businesses and workforce development professionals to understand today’s world of work.

I → People who like to “think and observe rather than act, to organize and understand information rather than to persuade”. They also prefer “individual rather than people-oriented activities”.
C → People who “like rules and regulations and emphasize self-control. They like structure and order, and dislike unstructured or unclear work and interpersonal situations”. They also “place value on reputation, power, or status”.
A → People who tend to be “creative, open, inventive, original, perceptive, sensitive, independent and emotional”. They rebel against “structure and rules” but enjoy “tasks involving people or physical skills”.
S → People who “seem to satisfy their needs in teaching or helping situations”. They tend to be “drawn more to seek close relationships with other people and are less apt to want to be really intellectual or physical”.
E → People who tend to be “good talkers and use this skill to lead or persuade others”. They also “value reputation, power, money and status”.
R → People who tend to be “assertive and competitive and are interested in activities requiring motor coordination, skill and strength”. They also prefer “concrete approaches to problem solving, rather than abstract theory”.

It looks simple but in reality, there is naturally more to finding an appropriate professional challenge than simply matching types.
