This manual provides a sequential procedure for conducting functional vocational evaluations for secondary school students as required by the Individuals with Disabilities Education Act. This evaluation procedure considers the interactions of the student with instructors, peers, and employers; training needs; work demands; environmental factors; and necessary adaptations. The model proposed involves a five-step progression of assessment appropriate for use with middle and secondary level students with disabilities. At each stage of the process, a counseling session is held with the student to determine if enough information has been provided to design an appropriate career education and vocational program. If not, the process proceeds to the next more involved stage of information gathering. A flow chart illustrates the sequence. The five stages are: (1) orientation/interview; (2) observation, inventories, and record reviews; (3) career exploration; (4) situational assessment; and (5) multi-agency planning and assessment. Sample forms, questionnaires, and interview protocols are provided for use in implementing the process. An appendix provides additional forms, formats, and lists. (Contains 28 references.) (DB)
