This paper describes the Vermont Interdependent Services Team Approach (VISTA), a decision-making process for determining the educational support service needs of students with deaf-blindness or other multiple disabilities. The paper also analyzes perceptions of VISTA held by experts in a variety of fields. Specifically, VISTA provides a team process for determining: (1) needed services to support a student's educational program; (2) educational relevance and necessity of the services; (3) functions of support services; and (4) frequency, mode, and location of service provision. A panel of 12 experts from major national organizations reviewed a revision of the VISTA procedures manual and found that the manual's content was relevant for students who have education support service needs, including students with deaf-blindness, and verified the content as logical, consistent with exemplary practice, and not particularly controversial. Differences among reviewers were found in philosophical orientation and approval of the manual's format. (Contains 13 references.) (DB)
