ELs are among the fastest-growing population in U.S. schools and comprise 9 percent of all students in grades PreK–12 nationwide (U.S. Department of Education, 2018). Despite the fact that ELs bring many assets with them to school, including their home language, they consistently perform at lower levels than their non-EL peers and have lower high school graduation rates (National Center for Education Statistics, 2014). This review focuses on interventions designed to address this achievement gap by improving the English language and literacy skills and/or content area achievement in mathematics, science, technology, engineering, or social studies of ELs in grades PreK–12.
The following research question guides this review:
- Which interventions improve English language and literacy skills among EL students in grades PreK–12?
- Which interventions improve content area achievement among EL students in grades PreK–12?
