A workplace literacy partnership project was conducted to upgrade the basic skills and productivity of 287 hourly wage earners of Winamac Spring Company (WSC) in Indiana. WSC paid employee wages for up to 24 hours of training and provided a classroom facility. El-Tip-Wa Adult Learning Center instructional staff provided basic skills training using work-related materials. Curriculum and learning modules were developed on an ongoing basis. Staff continually solicited feedback concerning employees' attitudes toward training by surveys and documented skill improvements through criterion-referenced tests. These tests showed measurable improvement in worker acquisition of skills taught. A majority of workers, supervisors, and technical personnel felt that job performance and worker attitudes improved. An external evaluation used the following methods: participant questionnaires; interviews with WSC managers, supervisors, and technical personnel and with instructional personnel and community representatives; pre-post test data; review of project materials; and analysis of productivity and cost information. Results showed the following: substantial gains in short-term mastery of course material; limited improvement in job performance; positive trends in productivity and cost measures; negligible impact on employee attitudes; and substantial commitment of WSC to the project. (Appendixes include a learning module on introduction to measurement and linear measurement and the external evaluation report.) (YLB)
