The Austin Independent School District (AISD) provides bilingual education and English-as-a-Second-Language (ESL) programs for limited-English-proficient (LEP) students. Mandatory evaluation of these programs involved the following: data from the Student Master File (information on each student's grade level, ethnicity, and socioeconomic status); data from the LEP student master file (information on students' LEP status, home language, and program service dates); programmatic and professional staff development details; Emergency Immigrant Program expenditure data; prior-year information on LEP students from Office of Program Evaluation reports; test scores; and participant responses. Achievement of former LEP students surpassed that of all AISD students on percentages passing the Texas Assessment of Academic Skills. Their attendance rates and grade point averages were similar to those seen districtwide. Potential retention rates and discipline rates were lower than districtwide rates. Achievement of current LEP students was generally below state and national norms. Participants reported that staff development was appropriate and useful. The number of LEP students attending AISD increased in recent years. Three appendixes contain text of the Texas Administrative Code; data on alternative language program/bilingual/ESL staff development; and a comparison of LEP students served versus LEP refusals.
