Topic Focus
English language learners are among the most academically at-risk groups in our schools today and their numbers will rise steadily in the near future. On average, ELL students receive lower grades, score below their classmates on standardized reading and mathematics tests, and are often judged by their teachers as academic "underachievers." According to annual state education agency survey data, more than 4.6 million ELLs were enrolled in the K–12 education system in 2000–2001. The What Works Clearinghouse (WWC) review focuses on interventions designed to improve the English language literacy or academic achievement of elementary school students who are English language learners.
