This study represents the first empirical test of the vocational personality of US school psychologists. Specifically, we investigated the personality of school psychologists using Holland's (1997) well-researched theory of vocational personalities and work environments. The sample consisted of 241 randomly selected members of the National Association of School Psychologists (NASP). The Self-Directed Search (Holland, 1994) was used to identify personality types. Results offered general support for the three-letter vocational personality code for school psychologists that is listed in the "Dictionary of Holland Occupational Codes" (Gottfredson and Holland, 1996).
