Abstract
Personal and interpersonal values were investigated to determine the effects of sex, grade level, and occupational groups in a high school population. Gordon’s Survey of Personal Values and Survey of Interpersonal Values were administered to the entire student body of two high schools in northern Illinois. Data were analyzed by a 2 X t X 5 ("ex by grade by occupational groups) analysis of variance. Results indicated that all values do not develop simultaneously, but are influenced in their development by the individual’s sex, grade, and occupational group. Grade effects were stable for personal values, but varied for interpersonal values. The effects of sex and occupational groups varied on both the personal and interpersonal values.
