A meta-analysis of selected studies on the efficacy of bilingual education was conducted and the results were compared with a traditional review of the same literature. When statistical controls for methodological inadequacies were employed, participation in bilingual education programs consistently produced small to moderate differences favoring bilingual education for tests of reading, language skills, mathematics, and total achievement when the tests were in English, and for reading, language, mathematics, writing, social studies, listening comprehension, and attitudes toward school or self when tests were in other languages. The magnitude of effect sizes was influenced by the types of programs compared, language of the criterion instruments, academic domain of the criterion instruments, random versus nonrandom assignment of students to programs, formula used to calculate effect sizes, and types of scores reported in the studies. Programs characterized by instability and/or hostile environments were as...

The Assessment of limited English speaking children usually includes the administration of instruments in both English and the primary language to establish dominance and/or handicaps of the child. To preclude misdiagnosis, the underlying assumption is that the instruments tap parallel aspects of proficiency in terms of technique or areas of language assessed. The objective of this paper is to acquaint users with the comparability of five commonly used language assessment instruments in English and Spanish according to their linguistic and psychometric qualities. Specifically, they will be compared across English and Spanish along the following parameters: 1) area of language measured: syntax, phonology or semantics; 2) domain assessed: home, school or neighborhood; 3) developmental comparability of items; 4) language variety or dialect. Technical qualities examined will include: information provided on proficiency classification, validity, reliability and norming. The following instruments will be compar...
