The technical appendixes are part of a study that explores 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) and training of staff (including training/certification in bilingual or English-as-a-Second-Language (ESL) instruction); 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, fourth of 4 of the final report, contains copies of the data collection instruments and notes on the sampling design, response rates, non-response adjustments, and analytic weighting approaches used.
