Holland Codes

John Holland started working on his theory of vocational choices in the 50s, culminating in his career-defining work, The Holland Occupational Themes.

Holland’s theory

The idea that forms the basis of Holland’s theory is that the careers you would enjoy are linked to your personality. Choosing a profession that matches your personality means that you are more likely to flourish at your job and find it fulfilling.

Holland identified six categories of personality, and the careers associated with them. No one’s personality fits neatly into just one category, but by finding which of the categories you are closest to, you will see the list of professions which correspond best to you.

Holland called the six categories he identified by the names: Realistic, Investigative, Artistic, Social, Enterprising, and Conventional. His theory is referred to as the Holland Codes or the RIASEC model – an acronym formed from the first letter of each category. Ever since Holland’s Occupational Themes came out, his theory has been widely used in careers counseling research and practice.
