"Read Naturally"[R] is an elementary and middle school supplemental reading program designed to improve reading fluency using a combination of books, audiotapes, and computer software. The program has three main strategies: repeated reading of text for developing oral reading fluency, teacher modeling of story reading, and systematic monitoring of student progress by teachers and the students themselves. The What Works Clearinghouse (WWC) reviewed three studies on "Read Naturally"[R] for English language learners. One study meets WWC evidence standards; one study meets WWC evidence standards with reservations; the remaining study does not meet WWC evidence standards. Based on the two studies, the WWC found no discernible effects in reading achievement and English language development for English language learners. Appendices include: (1) Study characteristics; (2) Outcome measures; (3) Summary of study findings included in the ratings; (4) "Read Naturally"[R] ratings; and (5) Extent of evidence by domain.
