A three-phase assessment was conducted to field test a curriculum developed to expand career horizons for both young men and young women and to help eliminate sex role stereotyping. Intended for grades 7-14, this curriculum emphasized the increasing options for women in vocational education programs and non-traditional careers. First, the curriculum was pilot tested using a first-draft version of all materials in two Illinois high schools with two classes. As a result, a few problems in implementing the curriculum and assessment instruments were identified and the materials were revised. In the second phase, the revised version was tried out in four Illinois schools with eight classes and resulted in further refinement of materials and administration procedures. In the final phase of the field test, the curriculum was used in seven Illinois schools with eleven classes. An analysis of the results showed that male and female students at all grade levels participating learned from and enjoyed the course. However, female students and students with female teachers seemed to be more sensitive to the problems of sex discrimination. Based on all the data, it was concluded that the curriculum could be used with male and female students in all parts of Illinois and at all secondary grade levels. (BM)
