This report describes the JobLink workplace literacy program conducted for employees of nine companies in Costa Mesa, California. The introduction provides background and describes the problem: one-third of the 2,870 workers had inadequate language and literacy skills. The next six chapters describe the problem, solutions, tasks, challenges, and discoveries related to these topics: (1) developing and delivering multimedia and Internet-based literacy instruction to working adults; (2) supporting companies' changes and improvements through worksite training; (3) involving supervisors in training programs; (4) measuring return on investment; (5) disseminating project results; and (6) continuing training after the project ends. The last chapter evaluates project results, reporting the following: 881 employees from the original nine plus an additional company were trained; students working in the multimodal lab showed more reading comprehension improvement than worksite students; lab, worksite, and distance education students showed significant differences in self-improvement; those who persisted (more than 100 study hours) showed the greatest improvements. The following conclusions are reported: multimedia materials provide literacy students an enhanced, self-paced environment; supervisor knowledge and support of training increases employee persistence and retention; and companies that established computerized learning centers on site have built an infrastructure for continued learning. Appendices contain the following: results of job analysis interviews; additional job analysis; distance learning pilot project; distance learning orientation module; worksite module sample activities; learner enrollment and assessment forms; student newsletters; newsletter for managers; and worksite module program brochures.
