The Holland hexagon

Holland Codes are career types created by psychologist John L. Holland.

Holland mapped these types into a hexagon which he then broke down into the RIASEC job environments :

  • Realistic - practical, physical, hands-on, tool-oriented
  • Investigative - analytical, intellectual, scientific, explorative
  • Artistic - creative, original, independent, chaotic
  • Social - cooperative, supporting, helping, healing/nurturing
  • Enterprising - competitive environments, leadership, persuading
  • Conventional - detail-oriented, organizing, clerical

Holland argues that 2-3 types dominate in each person.
