The Vocational Education Amendments of 1968 require the expenditure of 25 percent of the basic grant to States to provide the disadvantaged and the handicapped with vocational education programs.

The prime purpose of these guidelines is to serve as a basis for establishing compatibility among the States in planning, implementing, and evaluating programs and services for persons with special needs.
