The relationship between English language proficiency and academic performance among English learners: A subgroup analysis by home language background

Abstract

In U.S. K-12 public education, states' English language proficiency (ELP) standards and assessments have undergone changes in their content to correspond to the language demands of new academic content-area standards (e.g., Common Core State Standards). However, empirical investigations about how English learner (EL) students perform on the new assessments are limited despite the continued use of ELP assessments for making various decisions about students' academic paths. Addressing this gap, this study focused on criterion-related validity evidence by examining the relationship between ELP and content assessment performances of fifth-grade EL students in one state. We examined all EL students and EL home language subgroups. The results suggest that the ELP Reading subdomain was a significant predictor of content assessment scores in English language arts and mathematics; however, the patterns and magnitude of ELP and content relationship differed across different home language groups. Implications for practice, policy, and research are discussed. Educational relevance statementStates' standards-based ELP assessments play a vital role in making decisions about individual EL students' academic paths as well as in school planning for resources and instruction for EL students. The findings of the present study provide important validity evidence to support the intended use of ELP assessments. The study also underscores the importance of investigating within group variations, as the EL group is tremendously heterogenous in terms of their cultural and linguistic backgrounds, socioeconomic status, length of U.S. residence, and formal schooling experience. The results of the study shed light on a more nuanced understanding of the relationship between ELP and the academic performance of EL students from different home language backgrounds.
