A project to develop, implement, and evaluate a vocational English as a second language program for limited English proficient (LEP) adults is described. The major concern of North Orange County Community College District, California, was to serve the vocational education needs, and vocational English need in particular, of the limited English speaking immigrants and refugees who have a variety of language, educational, and cultural backgrounds. Literature reviews on the following topics are included: remedial education, research, questionnaires in research, vocational English instruction for LEP, program design, curriculum, program implementation and evaluation, and faculty of English as a second language. Questionnaires on vocational language programs were administered to vocational instructors of LEP adults and program coordinators of language programs in five educational institutions for adults. The following program materials were developed: a master plan, the curriculum, general and daily lesson plans, and instructional materials. Evaluation was undertaken with a standardized English proficiency test for LEP adults. Additional evaluation criteria were acceptance into vocational programs or college or university programs, and attainment of certificates. Vocational English as a second language (VESL) curricular content was developed to correlate with competency-based criteria of current vocational training programs, specifically machine shop and business skills. Additional materials include analysis of program results, sample questionnaires, evaluation criteria, VESL program descriptions, instructional plans, daily lesson plan samples, a student referral, and about 135 references.
