This research study was developed to investigate a group of Outstanding college personalities in Iran. The purposes of the study were: (a) to identify a "frequently nominated" group and an "infrequently nominated" group of University of Isfahan students based on the social criterion of "outstanding personality development"; (b) to determine whether or not "friendship nominations" unduly influenced the selection of "frequently nominated" students; (c) to determine whether or not "frequently nominated" and "infrequently nominated" students could be reliably differentiated on stressful life events, developmental histories, mental health adjustment, expressed needs, and descriptive data; and (d) to present a summary of the most striking and consistent findings on personality development of the "frequently nominated" students. This study concludes that 1. A "frequently nominated" group and an "infrequently nominated" group of normal Iranian student personalities, based on the social criterion of "outstanding personality development," can be identified and statistically differentiated. 2. "Outstanding" Iranian student personalities have greater affiliative capacities than other normal Iranian student personalities. 3. "Outstanding" Iranian student personalities possess ego strength, as evidenced by their desire to make decisions from inner self evaluations and to break parental standards, to a greater extent than other normal Iranian student personalities. 4. "Outstanding" Iranian student personalities do not practice self—sacrifice. 5. "Outstanding" Iranian student personalities are actualizing their capacities to a greater degree than are other normal Iranian student personalities. 6. "Outstanding" Iranian student personalities are not free from stressful situations, problems, or inner conflicts.
