This guide is intended to assist instructors and administrators in improving the vocational education of special needs students by providing supplemental services that have been authorized by the Carl D. Perkins Vocational Education Act of 1984. Discussed in a section on the implications of the act for disadvantaged and handicapped students are the law's vocational and prevocational mandates, vocational assessment, supplemental services, and identification of students. The second section covers in-class, out-of-class, and out-of-school instructional supportive services from the standpoint of the vocational instructor's role in providing supplemental services. Career awareness/prevocational counseling and exploration, vocational counseling, and parent-teacher contact are covered in a section on guidance counseling and career development. The fourth section, which deals with transitional services, outlines procedures for identification of job opportunities, job placement, and student followup. Concluding the guide is a section on corrective and other supplemental services. An appendix contains a brief bibliography of suggested sources of written and audiovisual materials and a sample listing of out-of-school support agencies. (MN)
