A sample of 559 males and 986 females enrolled in three Wyoming High Schools were administered the Edwards Personal Preference Schedule (EPPS).

No significant differences in mean scores of Edwards' college sample and the present high school sample were discerned. Sex differences on each of the scales did not uniformly follow those reported for Edwards' college sample.
