This paper describes the development and validation of the Cognate Awareness Test (CAT), which measures cognate awareness in Spanish-speaking English Language Learners (ELLs) in fourth and fifth grade. An investigation of differential performance on the two subtests of the CAT (cognates and noncognates) provides evidence that the instrument is sensitive to English—Spanish cognate awareness among elementary school-age Spanish-speaking ELLs. Cognates were highly correlated with the children's Spanish WLPB-R Picture Vocabulary scores, whereas noncognates were highly correlated to children's English WLPB-R Picture Vocabulary scores.

This study explores the role that socioeconomic status (SES), home and school language and literacy practices, and oral vocabulary play in the development of English reading skills in Latino English language learners (ELLs) and how these factors contribute differentially to English reading BILINGUAL CHILDREN'S ENGLISH READING DEVELOPMENT 121 outcomes for children of different ages and in different settings: 292 Spanish-speaking kindergarteners in mostly English instruction, 85 Spanish-speaking third graders in bilingual instruction, and 70 Spanish-speaking fifth graders in both English and bilingual settings. Data were analyzed using hierarchical regression. Findings indicate that for each sample, English oral vocabulary is a significant predictor of English reading accuracy and comprehension once SES and home and school language and literacy factors have been considered. Beyond oral vocabulary, however, there is considerable variability across samples in the home and school language and literacy variables that are predictive of English reading outcomes. The study points to the importance of looking closely at the texture of children's lives in coming to an understanding of second-language literacy development.

This study describes the development and validation of the Extract the Base test (ETB), which assesses derivational morphological awareness. Scores on this test were validated for 580 monolingual students and 373 Spanish-speaking English language learners (ELLs) in third through fifth grade. As part of the validation of the internal structure, which involved using the Generalized Partial Credit Model for tests with polytomous items, items on this test were shown to provide information about students of different abilities and also discriminate amongst such heterogeneous students. As part of the validation of the test’s relationship to criterion, items were shown to correlate with measures of word identification, reading comprehension, and vocabulary measures. Differences in performances for fluent English students and ELLs, students of varied home language environments, and different grade levels were noted. Additionally, the task was validated using a dichotomous scoring system to provide reliability and validity information using this alternate scoring method.

Two studies investigated technical aspects of a computer-mediated test, the Computerized Oral Proficiency Instrument (COPI), particularly in contrast to a similar tape-mediated test, the Simulated Oral Proficiency Interview (SOPI). The first study investigated how examinees used self-assessment to choose an appropriate starting level on the COPI. The second study looked at examinees' planning and response time on the COPI, and the factors that affected their use of time. Fifty-five university students took the COPI and SOPI in one of three languages: Arabic, Chinese, or Spanish. Results show that the majority of examinees (92%) were able to use the self-assessment instrument to select test tasks at appropriate difficulty levels. However, the COPI starting level (which was based on examinees' self-assessment) might have been problematic for a small proportion (8%) of the examinees who appeared to choose tasks that were too difficult for them. As for planning and response time on the COPI, different amounts of time were used across four main levels of proficiency. Examinees with the highest proficiency levels tended to use less planning time but gave longer responses.
