This study examines obstacles faced by limited English-speaking adults in bilingual vocational training projects. Methods and procedures used in nine federally funded bilingual vocational training projects to resolve the identified obstacles are documented, and their usefulness is assessed. The purpose and background of the study are first surveyed. The obstacles to trainee participation encountered in the projects are then identified. The discussion next focuses on selected aspects of planning that enable project staff to identify and prevent potential obstacles to participation among prospective trainees and on mechanisms and procedures for identifying obstacles during outreach, screening, and recruitment; during intake; in the classroom or on the work site; and through trainee counseling. These attendance obstacles are cited and resolutions for each are presented: personal and family problems, health problems, transportation problems, lack of housing, and lack of financial resources. Discussion follows of these instructional obstacles and available resolutions: adapting instruction to trainees' levels, difficulties resulting from absences, adapting to styles of trainee participation, inappropriateness of instructional materials, trainees' anxieties about training, and inappropriate behavior. Suggestions are made for mechanisms and procedures to identify, prevent, and resolve obstacles to participation on a systematic basis. Appendixes include project descriptions and a bibliography. (YLB)
