The order of the Holland Code variables is critical. Any change in the
order alters the personality type. Below are descriptions of the six
variables that constitute the Holland Code.
Realistic (R): Realistic occupations frequently involve work
activities that include practical, hands-on problems and solutions. They
often deal with plants, animals, and real-world materials like wood,
tools, and machinery. Many of the occupations require working outside, and
do not involve a lot of paperwork or working closely with others.
Investigative (I): Investigative occupations frequently involve
working with ideas, and require an extensive amount of thinking. These
occupations can involve searching for facts and figuring out problems
mentally.
Artistic (A): Artistic occupations frequently involve working with
forms, designs and patterns. They often require self-expression and the
work can be done without following a clear set of rules.
Social (S): Social occupations frequently involve working with,
communicating with, and teaching people. These occupations often involve
helping or providing service to others.
Enterprising (E): Enterprising occupations frequently involve
starting up and carrying out projects. These occupations can involve
leading people and making many decisions. Sometimes they require risk
taking and often deal with business.
Conventional (C): Conventional occupations frequently involve
following set procedures and routines. These occupations can include
working with data and details more than with ideas. Usually there is a
clear line of authority to follow.
