Four studies compiled in this document cover career awareness, academic achievement, career decision-making, and other ways of assessing effectiveness. Each area is developed through (1) literature reviews, (2) input gathered from state coordinators of career education and from local practitioners, and (3) reported data which represents application of the specific treatment. The papers include data tables, bibliographies, and appendixes, in addition to extensive descriptions of projects reviewed for the studies. Major conclusions resulting from these studies are reported as follows: (1) Educational programs designed to develop career awareness in students are making statistically significant changes in student development; (2) positive changes in the self concepts and work habits of some students have taken place, and further studies may net more hard data that career education can aid the development of students' acquisition of fundamental skills; (3) career education programs have the potential power to produce career decision-making effects which are specific and desirable, but a sound theoretical research base for prescribing and reporting decision-making activities seems lacking; and (4) students in grades K-12 generally respond positively to participation in career education programs and their attitudes appear to improve with increased exposure to career education programs and services.
