Which term refers to the degree to which personality types need a particular environment according to John Holland?

The term that refers to the degree to which personality types need a particular environment, according to John Holland, is congruence. In Holland's theory of career choice, congruence describes the fit between an individual's personality type and their work environment. When there is a high level of congruence, individuals tend to experience greater satisfaction and success in their careers, as their personal values, interests, and abilities align closely with the demands and culture of their work environment. This concept is crucial in understanding how to guide individuals toward careers that will be fulfilling and appropriate for their personality types, thereby maximizing their potential for success.

Other terms like alignment, compatibility, and affiliation do not encapsulate the specific concept of the fit between personality types and environments as distinctly as congruence does in Holland's framework.
