The report presents results of a study of: the type, content, duration, and intensity of instructional services provided to limited-English-proficient (LEP) students in the United States; administrative procedures associated with these services (including procedures for identifying students for entry into and exit from these special services); the numbers, types, and qualifications (including first and second language proficiency) of staff and the costs of these special services. Data were gathered through: mail survey of LEP coordinators at state education agencies (n=51), local school districts (n=745), individual schools (n=1,835), and teachers (n=949) of LEP students; telephone survey with LEP coordinators at school districts (n=99) and schools (n=263); case studies of ten school districts; and Title VII file reviews (n=192), including reviews of Title VII applications and interviews with project directors. The study covered the 1991-92 school year. This volume, third of 4 of the final report, contains the case study reports for ten diverse school districts (rural, small town, suburban, medium-sized metropolitan, large metropolitan). Reports describe district characteristics in the areas noted above, and local staff's recommendations for program improvement. (MSE)
