Extending Holland's Hexagon: Procedures,Counseling Applications,and Research

Since its introduction nearly 25 years ago, Holland's (1985) hexagon has remained in skeletal form. The hexagon is used to depict similarities and differences among occupations—but only six general types of occupations. The authors show in this article how to extend the basic concepts embodied in the hexagon. Procedures for locating counselees and occupations on the hexagon are illustrated. These procedures, which are compatible with scores from a wide variety of assessment instruments, can help counselees identify and explore occupational options. The authors also report research on the hexagon locations of 27 career groups.
