John Holland's Theory of Career Choice (RIASEC) maintains that in choosing a career, people prefer jobs where they can be around others who are like them. They search for environments that will let them use their skills and abilities, and express their attitudes and values, while taking on enjoyable problems and roles. Behavior is determined by an interaction between personality and environment.
Holland Codes are one of the most popular models used for career tests today. Holland argued that the choice of a vocation is an expression of personality. There are six personality types in Holland's model and most people will fit into a few of the categories:
• Realistic: practical, physical, concrete, hands-on, machine, and tool-oriented
• Investigative: analytical, intellectual, scientific, explorative, thinker
• Artistic: creative, original, independent, chaotic, inventive, media, graphics, and text
• Social: cooperative, supporting, helping, healing/nurturing, teaching
• Enterprising: competitive environments, leadership, persuading, status
• Conventional: detail-oriented, organizing, clerical
