Purpose of the handbook is to ensure a commonality of concept and practice in bilingual education for the San Ysidro School District (California). Prefaced by excerpts from the state legislation enacting bilingual education and a statement of the district's bilingual-bicultural education philosophy, the handbook delineates the membership, selection procedures, and duties/responsibilities of the district bilingual advisory committee and the school bilingual committee. A section on the roles of teachers and aides addresses their duties and responsibilities, how to work with others, which students to help, what to do, nature of their contributions, whom to work with, and how their work is appreciated. Entry criteria for Spanish or English reading is listed along with the principal sources of instruction for grades K-5. The handbook includes a pupil profile card; a Spanish student progress card; sample daily class schedules for both the English-only and the bilingual programs; descriptions of the Language Development Specialist Program, the various tests used, the Bilingual Syntax Measure and its categories; and the district's testing schedule. Appended are sample letters to parents, reclassification forms and notices, and sample writing exercises. (NQA)
