This paper suggests some principles and practices of vocational and technical education for the public education system. Five conclusions emerge from the paper: (1) Vocational and technical education are essential parts of the modern curriculum for public education; (2) public education is responsible for the vocational education of high school youth, out-of-school youth, and adults; (3) minimum enrollments for vocational education programs are 500, while optimum programs can be reached with enrollments of 1,300; (4) large cities of 200,000 or more normally have sufficient tax and student bases to provide comprehensive vocational education programs, while suburban and rural districts do not unless they join together; (5) vocational and technical education programs are sound educational investments planned to serve the needs of the people and of business and industry; and they deserve the full support of people concerned with the modernization of educational programs throughout the nation.
