A clinical simulation technique was used to investigate how future school principals view the roles of professional school counselors, particularly as those responsibilities are represented in the ASCA National Model[R]. The 244 respondents were principals-in-training (i.e., graduate students) officially enrolled in educational administration programs at member institutions of the University Council for Educational Administration. These principals-in-training were able to differentiate between appropriate and inappropriate roles of professional school counselors, and the results generally were independent of their demographic characteristics.
