This guidebook focuses on the first of five steps included in a planning system for improving local secondary and postsecondary program and facilities accessibility: identifying barriers. The first five sections of the booklet are comprised of self-instructional descriptions of five needs-assessment procedures that can be used to identify barriers: (1) surveys and questionnaires, (2) nominal group technique, (3) Delphi technique, (4) outside experts, and (5) community impressions. Section 6 provides seven sample surveys which have been demonstrated to be valid and reliable instruments for identifying and assessing barriers to vocational education programs and facilities. The final portion comprises the bulk of the guidebook and contains an architectural accessibility survey. There are six sections in the survey, each covering different parts of the site and building: site, entrances, vertical circulation, building products, functional spaces, and special services. In addition to these six sections, two modules are included for separate surveys which may apply to any or all of the six sections; these two modules focus on accessibility routes and doors. (LRA)
