One study of
Read Naturally® that falls within the scope of the Students with Learning Disabilities review protocol meets What Works Clearinghouse (WWC) evidence standards. The study includes 20 students with learning disabilities from the 4th to the 6th grade in one parochial elementary school in Washington State.
Based on this study, the WWC considers the extent of evidence for Read Naturally® for students with learning disabilities to be small for reading fluency and writing. The one study that meets WWC evidence standards did not examine the effectiveness of Read Naturally® for students with learning disabilities in the alphabetics, reading comprehension, general reading achievement, math, science, social studies, or progressing in school domains.
