Vocational maturity: The effects of school,grade, curriculum and sex

The purpose of this study was to investigate the usefulness of the Career Maturity Inventory (CMI) as a measure of vocational maturity. Using longitudinal data collected over three points in time from three large school systems, answers were sought to each part of the following question: Does the mean VDI score differ (a) among three school systems, (b) among four curricula, (c) among three grades, (d) and between males and females? The statistical methodology used was analysis of variance. The findings indicate that scores on the CMI incrementally increase by grade level. However, the rate and level of this increase is influenced by sex, school, and curriculum effects.
