Comprehensive work experience and vocational guidance activities were established at the middle school level and their effects on career maturity and attitudes toward school of ninth graders were tested. The project was conducted at the Bowling Green Junior High School (Kentucky) during the academic school year of 1975-76. (The school supports a comprehensive K-12 career education program; results of the study should not be generalized to school settings that do not offer a career oriented curriculum.) Experimental variables in the research design were the guidance oriented work experience component and the Life Career Development System (LCDS). The work experience component was conducted entirely on the Western Kentucky University campus. The LCDS was conducted in the junior high school utilizing joint university and public school teacher facilitation efforts. The Career Maturity Inventory (CMI) and the School Sentiment Index (SSI) were administered to all experimental and control subjects. Data was collected and reported from sponsors, students, parents, and teachers. Conclusions and recommendations were made based on empirical findings, programmatic results, and subjective observations. In general the study was viewed as a success, the major recommendation being that decisionmakers and curriculum specialists at State and local levels strongly consider implementation of career work experience programs for the junior/middle school as a major vehicle for sound curricular decisionmaking on the part of students. Appendixes comprise approximately one half of the document and include the teacher information sheet, parent information letter and permission slip, sponsor contracts, sponsor information sheet, School Sentiment Index, advisory committee abstract, agenda, and membership, third party evaluation/comprehensive guidance and work experience, and third party evaluation/LCDS.
