John Lewis Holland - Holland's Theory of Vocational Personalities and Work Environments

John Lewis Holland
1919-2008

John Holland developed a theory about vocational personalities and work environments.
He developed the theory that people are made up of 6 basic personality types and for a contented life people should work in work environments that match their personalities.

He started his research in the 1950's and developed the VPI or Vocational Preference Inventory.  Then in 1970, he published the Self-Directed Search as a way to identify personality type and occupational awareness.
  
Theories of Types

         6 basic personality types with one being dominant.

         6 different types of work environments parallel the personality types

         If we understand both personalities and work environments then we can

help people find jobs/life that are very fulfilling



         Understanding self-knowledge crucial, be insightful about ourselves

What are we good at, not good at, interests and competency

         Understanding that interests doesn’t necessarily mean you are

competent at it.

Concepts in Holland’s Theories


Personality Types and Work Environments fall in the same categories

        Congruence
                  The relationship of the personality to the work environment

                  Personality Realistic then look at jobs in Realistic category

Major role of career counseling!


         Differentiation

                  Most people have 2-3 dominant types

                  Differentiated individuals have clear interests and clustering

         Undifferentiated are people that have interests that fall

across many of the ‘types’ and are not ‘clear’


With undifferentiated typology – may find it more difficult to

find an environment to fit one’s needs


With differentiated in an undifferentiated environment, might

be frustration with things required that don’t interest one.                 

                         When talking to individual, we might discuss how a work

environment meets their needs, or doesn’t and what might be frustrating or not.  Our work may not be the only place that we get our needs met.


                  Differentiated/Undifferentiated

Differentiated environment – Assembly line, do same thing day after day

Undifferentiated environment – University work as a professor – can teach (social); do consulting (enterprising); and research (investigative)


         Consistency

Letters closer to each other seem to fit better in jobs

and personality

                  Letters farther away, not as consistent in job descriptions


         Identity

                  What kind of goals do they have for their career

                           How are they going to reach them

                  Refers to the clarity and stability of a person’s

current and future goals

                  Also refers to the stability of the work environment

                  “Does the client have a clear notion of her/his career desires

and a plan to reach them?” – this measures identity.
