Holland Code

The Holland Code is based on John Holland’s theory about vocational development. In sum, the concept is that people, environments, and majors can all be coded based on six career types. Some people will quickly and easily identify themselves as being primarily one type, while others will need two or three themes to describe them well. Likewise, occupational environments are often complex and need two or three theme letters to describe them adequately. The Holland themes are located around a hexagon to illustrate the relationship between themes. Once you understand the Holland Code, there are multiple resources to identify associated occupations and majors.
