The rubrics are designed for productive use (speaking and writing) of English and Spanish in two-way bilingual immersion programs. The rubrics were developed by classroom teachers working in elementary school Spanish partial immersion programs, in consultation with a special education teacher, reading specialist, middle school partial immersion teacher, and researchers. The instruments were designed to be used in authentic classroom situations, generate information useful in assessing student progress throughout the year, provide data useful in directing subsequent teaching, and articulate target expectation for language competency designed to parallel state and local goals. Introductory sections describe the materials' underlying principles, what is not assessed by them, appropriate tasks, rubric composition, uses, and scoring, and include a glossary of related terms. A form is included for each language and grade level for both speaking and listening. (MSE)
