Measures of the perception of occupational prestige and vocational maturity of 313 high school students representing grades 9 through 12 were investigated together with variables: father's occupation, occupational choice, grade level, age, intelligence, verbal and non-verbal abilities, and reading and math achievements. Significant correlates of the perception of occupational prestige, showing no sex differences were vocational maturity (p .001), educational level associated with father's occupation (p .001), IQ (p .001), verbal ability (p .001), non-verbal (p .001), reading achievement (p .001) and math achievement (p .001). There was no correlation, however, between the perception of occupational prestige hierarchy must have been established much earlier in childhood, at least by grade 9 or 13 years of age. Data on vocational maturity as measured by the Crites Vocational Development Inventory Attitude Scale are also presented and discussed. References and tables are included. (Author)
