This manual was developed to help supplemental teachers dealing with special needs vocational students, especially in Missouri. The manual provides information on the role of the supplemental teacher, definitions of various types of special needs students, and tips on the following topics: (1) eliminating attitudinal barriers hindering students who are members of special populations; (2) maintaining rapport among supplemental and assigned vocational teachers; (3) writing vocational plans; (4) working with students who are disadvantaged; (5) working with students who have limited English proficiency; and (6) working with students who are disabled. Resources and appendixes make up most of the manual. Resources listed include a description of the Missouri Instructional Materials Laboratory, instructional materials for special populations, Missouri Vocational Resource Center, Missouri LINC, Missouri Special Education Dissemination Center, resources for assistive devices and accommodations, additional resources, and a directory of organizational resources for people with disabilities. Six appendixes contain the following: the Carl D. Perkins Vocational and Applied Technology Education Act, P.L. 101-392, and other legislation; support services/curriculum and equipment modification; how to write and use learning activity packages; written vocational plans; supplemental teacher recordkeeping; and a vocational planner's guide to the Perkins legislation.
