A study investigated instructional administrative practices in workplace English-as-a-Second-Language (ESL) programs and lessons learned in their implementation, with special attention given to innovative practice and its context. Data were drawn from a survey of 22 workplace literacy programs with culturally diverse populations in a variety of industries in Illinois and Indiana, and from four in-depth program examinations. Program aspects studied include: goals; adjustments for multi-ethnic populations; philosophical or practical orientation; educational strategies; teaching methods; approach to cultural issues; teacher and volunteer staffing; teacher and volunteer training; needs analysis; program evaluation; student identification and recruitment; outreach efforts; and support services. Results are summarized in these areas: curriculum goals; program history; hours; instructional providers; union involvement; program origins; financial support; participant recruitment and selection; support services; need analysis, assessment, and evaluation; obstacles to program success; key features of effective programs; trainer recruitment and selection; teaching approaches and methods; program design and populations served; program orientations; potential contradictions or conflicts; model program design; and implications for practice. Appended materials include information related to site selection and survey. Contains 121 references. (MSE) (Adjunct ERIC Clearinghouse on Literacy Education)
