The counseling profession has changed emphasis over the past 20 years reflecting a movement in the field from public school to community service to private business. Consequently there has also been a change in the profile of counselor trainees. Data from students (N=238) having attended the counselor training graduate programs at Indiana University over the past 20 years were organized and entered into a management information system for future reference. The time period was divided into five 4-year eras in which various societal changes occurred. Results from the Fundamental Interpersonal Relations Orientation Scale (FIRO-B), the Rotter Internality-Externality Scale, the Sixteen Personality Factor Questionnaire (16PF), the Rokeach Dogmatism Scale, and the Strong-Campbell Interest Inventory (SCII) were analyzed in order to track any significant variances among the eras. The results showed that males and females differed with respect to dogmatism, locus of control, and some FIRO scales. The SCII theme scores and academic comfort scale responses remained constant across the eras. The results suggest that students who select counseling as a profession possess certain core characteristics. While some data suggests that the profile of counselor characteristics for this student body has changed significantly in the past 20 years, the change in the male/female gender ratio appears to be the single best explanation for adjustments in the psychological profile.
