This report is the fourth in a series of volumes published periodically by NCES to describe the condition of vocational education (now called "career and technical education" or CTE) in the United States during the period from 1990 through 2005. Based on data from 11 NCES surveys, the report describes CTE providers, offerings, participants, faculty, and associated outcomes, focusing on secondary, postsecondary, and adult education. The report is organized into three main chapters addressing, where possible, the following key questions related to CTE at the secondary, postsecondary, and adult levels: (1) What institutions provide CTE? (2) What is offered? (3) Who participates and what courses and majors do they select? (4) Who teaches CTE? and (5) What are the outcomes associated with CTE participation, including academic attainment, postsecondary education, and employment and earnings? A summary chapter provides selected findings from the report, and compares key characteristics across the three education levels. Finally, Appendix A describes the datasets and statistical procedures used in the report, and Appendix B contains a glossary. (Contains 101 tables, 2 exhibits, and 4 figures.)
