Evidence suggests that occupational prototypes have an impact on career decisions yet literature provides only a limited understanding of the nature of these prototypes. This paper presents a small-scale grounded theory study to explore the prototypes of four occupations. Data were collected from 24 psychology undergraduates through four focus groups. Participants were asked to evoke a typical member of each of four occupational groups and describe their prototype in detail. A classic grounded theory analysis identified the characteristics which were symbolised by the features of the prototypes and resulted in eight dimensions: warm, energetic, fun, intelligent, conventional, highbrow, successful and cool. The discussion explores the dimensions in the light of existing literature and suggestions are offered for practice.
