Congress, using Public Law 94-482 entitled Education Amendments of 1976, instructed the National Center for Education Statistics (NCES) to develop, implement, and operate the Vocational Education Data System (VEDS). As mandated by legislation, the primary purpose of VEDS is to provide a national reporting system to generate uniform data from the States to support the decision-making activities of Congress with respect to the establishment of vocational education policies. This study was designed to enhance the understanding of VEDS and to assess the VEDS methodology and data quality for each state. The assessment resulted in the development of a VEDS implementation and operation status report for each State which documented the degree of correspondence between VEDS and State definitions, and between VEDS and State data elements; the identification of a State's ability to provide data related to each VEDS data requirement; and the quality and accessibility of VEDS data.
