A study was conducted to identify, assemble, and summarize all studies on the effects of vocational education that were reported from 1968 to 1979. Computer searches, reviews of bibliographies, card catalogues, direct solicitation of reports, and consultant recommendations yielded 117 local, state, regional, and national studies that met the criteria for the review. Studies were categorized according to the type of dependent variable that they addressed, as well as the level of schooling. The dependent variables fell into three broad categories: employment, education, and ancillary effects. In the area of employment effects, the results suggested that a higher percentage of vocational graduates (compared with nonvocational graduates) are employed upon graduation from high school; however, the unemployment rates for the two groups are not significantly different. At the postsecondary level, two comparative studies found that postsecondary vocational education graduates experienced less unemployment than did individuals who did not have postsecondary training or who were enrolled in a nonvocational postsecondary program. In the area of educational effects, all twenty-one of the state and local studies that addressed satisfaction with training at the secondary level reported that the majority of the vocational students were satisfied with their training.
