What does the No Child Left Behind Act emphasize for English Language Learners in the context of education?

The No Child Left Behind Act emphasizes annual testing in English as a critical measure for holding schools accountable for the academic achievement of all students, including English Language Learners (ELLs). By requiring annual assessments, the act aims to monitor the progress of ELLs in acquiring English language skills while also ensuring they meet academic standards in various subjects. This focus on testing in English allows educators and policymakers to identify gaps in learning and effectiveness of instructional strategies aimed at supporting ELLs' language development and overall educational performance.

Each of the other options, while potentially beneficial in various contexts, are not central to the focus of the No Child Left Behind Act. The act does not specifically mandate increased funding for bilingual programs nor does it emphasize testing students in their native languages. Additionally, the elimination of standardized testing is contrary to the core principles of the act, which seeks to standardize and enhance accountability measures across schools.
