The author reviews the literature on vocational development with an emphasis on instruments which measure vocational maturity. This study examines differences in the vocational maturity of women across different levels of internal-external (I-E) control and typical versus atypical vocational choice. The study made the following predictions: (1) internally-controlled women will have a higher vocational maturity score than externally-controlled women; (2) women making atypical vocational choices will have higher vocational maturity scores than those making typical choices; and (3) an interaction between type of choice and perception of control with respect to vocational development will exist. Using Crites' Vocational Development Inventory and MacDonald-Tseng's I-E scale to measure vocational maturity, the author proposes utilization of the I-E control construct in examining vocational maturity of college women in order to contribute to an understanding of the vocational choice process.
