Equity is a significant area of public administration which is integral to all disciplines that relate to the public interest, including vocational education. Vocational education is designed to achieve equity. The Vocational Education Act of 1963 mandated ready access of all persons of all ages in all communities to vocational education of high quality and suited to their needs and interests. The 1968 Amendments reinforced this directive, and sex equity was clearly stipulated in the 1976 Amendments. Vocational education was further linked with employability of any person with passage of such laws as the Comprehensive Employment and Training Act. A chief barrier to equity is absence of public interest. In public administration the improvement of testing is a feasible way to effect equity. Agencies should be required to show evidence of criterion-related, content, or construct validity of their personnel selection procedure. As regards research and policy recommendations, public interest should be the foundation of equity, enrollment should be regularly researched, intergovernmental fiscal relationships in vocational education should be studied from the standpoint of equity, and employability and energy equity should be studied.
