A study was undertaken to examine psychometric properties of "La Prueba Riverside de Realizacion en Espanol" (PRRE) and the "Spanish Assessment of Basic Education" (SABE) when administered to a sample of limited-English-proficient students, grades 1 through 8. Spanish-language versions of both tests were used for the study. Subjects included a total of 2,634 students who were enrolled in 19 elementary schools in Chicago and who participated in a Spanish bilingual education program. The instruments, both of which include reading and mathematics subtests, were administered by bilingual teachers who received inservice training to prepare them for their part in the study. In addition to analyses of test results, questionnaire data from participating teachers were assessed. The teacher questionnaire covered seven areas--item difficulty, test instructions, test fit with the curriculum, language correctness and appropriateness, racial or ethnic test bias, print size and illustrations, and cultural relevance of items. Results indicate that the PRRE and SABE are acceptable for the population assessed. The instruments are essentially similar in terms of psychometric properties and in teachers' ratings of test characteristics. Nine data tables are included. (TJH)
