"Read Well"[R] is a reading curriculum for kindergarten and first-grade students whose goal is to increase students' literacy abilities. The program provides instruction in phonemic awareness, phonics, vocabulary, comprehension, and fluency. The What Works Clearinghouse (WWC) reviewed five studies on "Read Well"[R] for English language learners. One of these five studies meets WWC evidence standards; the remaining four studies do not meet either WWC evidence standards or eligibility screens. Based on the one study, the WWC found no discernible effects in the reading achievement domain and potentially positive effects in the English language development domain for English language learners. The conclusions presented in this report may change as new research emerges. Appendices include: (1) Study characteristics: Frasco, 2008; (2) Outcome measures for the reading achievement domain and the English language development domain; (3) Summary of study findings included in the rating for the reading achievement domain and the English language development domain; (4) "Read Well"[R] rating for the reading achievement domain and the English language development domain; and (5) Extent of evidence by domain.
