Evaluative information is provided on 18 completed workplace literacy classes conducted in the Seattle-King County, Washington, area for 218 limited English proficient workers. The programs were operated by the Employment Opportunities Center and the Refugee Service Federation. Participants were members of the following ethnic groups: Vietnamese, Chinese, Cambodian, Lao, Japanese, Korean, Filipino, Thai, Ethiopian/Eritrean, Mexican, Central American, South American, Eastern European, and Soviet/Russian. Training sites were: Avtech Corporation, Eldec Corporation, Paine Corporation, and Pacific Circuits (electronics); Burien Terrace and Pinehurst Park (nursing homes); HFI Foods and Oberto Sausage (food processing); and the Sheraton and Westin Hotels. Factors affecting performance outcomes included workforce reductions due to the 1991 recession, variables in forming classes, pressure from supervisors and/or co-workers, overtime and work schedules, and limitation on the number of sites. Gains in pre-to-post program test scores, documented attainment of competencies, post-program assessments by supervisors, and continued employment at follow-up indicate that the majority of the participants have made progress in specific job-related language skills. In addition, demographic data indicate that the 18 classes have served people in need of specialized workplace literacy training. Many of the people served work in production-oriented, mostly technical jobs, and most have stayed with the same employer for a considerable time. A brief profile of each of the 18 classes is appended. (Adjunct ERIC Clearinghouse on Literacy Education) (LB)
